Abstract
PURPOSE Knowledge of how blood perfusion is affected during and after reconstructive surgery is of great importance to predict the survival of grafts and flaps. When commonly used reconstructive procedures were developed a century ago, they were based on empirical observations of clinical outcome. METHODS This is a comprehensive literature review that summarizes the current state of knowledge regarding microvascular perfusion monitoring during oculoplastic procedures. RESULTS Over the years, a number of techniques for perfusion monitoring have been developed as an attempt to be more objective than clinical examination using traditional methods such as observations of skin temperature, turgor, color, smell, and capillary refill time. There are limited publications regarding microvascular perfusion monitoring during reconstructive procedures in the periocular area. Modern laser-based techniques have been attractive due to their noninvasive nature. CONCLUSIONS Today, modern, noninvasive techniques are available to monitor perfusion during and after surgery. This has increased our knowledge on the perfusion in common oculoplastic surgery procedures. A detailed understanding of how blood perfusion is affected will hopefully allow the improvement of surgical techniques for better clinical outcome.

The Effect of Visualization Techniques on Students of Occupational Therapy during the First Visit to the Dissection Room. Healthcare (Basel) 2022; 10:healthcare10112192. [PMID: 36360533 PMCID: PMC9691158 DOI: 10.3390/healthcare10112192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 10/10/2022] [Accepted: 10/24/2022] [Indexed: 11/06/2022] Open
Abstract
Background: Part of the basic teaching of human anatomy are prosection sessions with a human corpse, which may generate stress or anxiety among students. The objective of this work was to study how, through the visualization technique (a coping technique), these levels could be reduced before starting prosection classes. Methods: A cross-sectional pilot study was conducted involving first-year students who had never participated in screening sessions. Prior to the visit, occupational therapy students underwent a viewing session (visualization technique). On the day of the visit, before and after the screening session, an anonymous questionnaire was distributed to find out about aspects of the students’ experiences, such as their feelings and perceptions. The State−Trait Anxiety Inventory was used to assess anxiety. Results: The baseline levels of anxiety measured remained stable (from 18.5 to 18.2 points), with no differences being found (p > 0.05). The levels of emotional anxiety measured fell from 15.2 to 12.6 points (p < 0.05). Before starting the class, there were six students (17.1%) with anxiety criteria, and this figure was doubled at the end of the session (33.3%) (p < 0.05). Conclusions: Sessions in a dissection room can cause stressful experiences and change the emotional balances of some students. The results obtained and published here showed no significant differences after the visualization technique. We found that the students believed that the prosection sessions were very useful for teaching anatomy.

Hafez SA. Design for assessment of dissection in anatomy laboratory based on group identification of structures and peer evaluation. ANATOMICAL SCIENCES EDUCATION 2022; 15:1045-1059.

Abstract
Dissection is a unique multisensory educational experience and is essential to learning the anatomical construction of the human and animal bodies. This study aims to introduce a specialized design for the assessment of dissection and to discuss the assessment's attributes. The design was a product of the "assessment drives learning" concept and was developed to motivate students to dissect. Students were awarded "dissection points" based on prior group dissection and identification of structures. Students' perception of the design was examined, and content analysis was performed. The assessment consisted of two parts: the first assigning each student group structures to "pin" on their previously dissected cadavers; the second was a group peer evaluation. The most critical factor for the assessment's success was careful selection of structures assigned to students to pin. The assessment was fit for the purpose, valid, reliable, and had a significant educational impact. Eighty-three percent of students (n = 116) recommended maintaining the assessment design, as they felt it promoted a deep approach to learning as well as teamwork while reducing stress to a minimum. A strong correlation (Spearman's rho = 0.46, P < 0.0001) was present between the high rating of the design and the number of structures learned, as well as, high rating and lower stress level (Spearman's rho = 0.40, P < 0.0001). There was no apparent influence of grades on student perception of the effectiveness of the assessment. This specific design of evaluation could be used as part of anatomy education in veterinary and medical schools.

Abstract
It is increasingly common to produce physical anatomical medical models using high-fidelity multiproperty 3D printing to assist doctor-patient communication, presurgical planning, and surgical simulation. Currently, most medical models are created using image thresholding and traditional mesh-based segmentation techniques to produce mono-material boundaries (STL file formats) of anatomical features. Existing medical modeling manufacturing methods restrict shape specification to one material or density, which result in anatomically simple 3D printed medical models with no gradated material qualities. Currently, available high-resolution functionally graded multimaterial 3D printed medical models are rigid and do not represent biomechanical movement. To bypass the identified limitations of current 3D printing medical modeling workflows, we present a bitmap-based "voxel" multimaterial additive manufacturing workflow for the production of highly realistic and flexible anatomical models of the neonatal lower limb using computed tomographic ("CT") data. By interpolating and re-slicing a biomedical volumetric data set at the native 3D printer z resolution of 27 μm and using CT scan attenuation properties (Hounsfield units) to guide material mixing ratios, producing highly realistic models of the neonatal lower limb at a significantly faster rate than other manufacturing methods. The presented medical modeling workflow has considerable potential to improve medical modeling manufacturing methods by translating medical data directly into 3D printing files aiding in anatomical education and surgical simulation practices, especially in neonatal research and clinical training.

Abstract
The understanding of human anatomy has been an endeavour spanning thousands of years from the Egyptians and Greeks in antiquity to the present day. Scholars and scientists have overcome great barriers to discover the inner workings and complexities of the human body, from personal challenges and prejudices to obstacles placed by society. Our present understanding of anatomy has accumulated over centuries, and progressive generations of physicians have contributed to the ever-growing evidence-based knowledge. This article explores the contributions made by Vesalius and his contemporaries in the first half of the sixteenth century. These enlightened scholars advanced anatomical knowledge and, perhaps more importantly, the scientific method, directly impacting the mindset and methodologies of future anatomists. Individuals such as Berengario da Carpi and Gabriele Falloppio produced bodies of work during their lifetime that were not only important in disputing the teachings of Galen of Pergamon, which had been accepted as almost unquestionable truths for a thousand years, but also instrumental in developing a new generation of scientists. The anatomists of the late renaissance were unable to resolve many of the factual inaccuracies of Galenic teaching but provided the groundwork for scientific thinking which future generations of anatomists benefited greatly from. The principles of documenting what is observed and establishing a methodical approach to question discrepancies in experiments would go on to influence physicians such as Harvey and Malpighi to investigate and draw correct conclusions in their research and ultimately advance our understanding of human anatomy to what it is today.

Abstract
BACKGROUND The use of 21st Century technology in anatomy teaching and the recent crisis caused by the Coronavirus pandemic has stimulated anatomists to ponder the ethics surrounding the utilisation of digital images from human bodies of known and unknown provenance in teaching. AIM This novel study explores the awareness of southern African anatomy educators regarding the provenance and ethical use of human material in digital resources for E-learning purposes. MATERIALS AND METHOD Anatomy educators (both members and non-members of the Anatomical Society of Southern Africa including postgraduate students in anatomy) located in 15 health sciences facilities in southern Africa were asked to participate in the survey which consisted of an anonymous, cross-sectional, questionnaire conducted on an online research data system, REDCap. RESULTS While 52% of respondents used E-learning resources sourced from their own departments for teaching, only 58% of these had knowledge of the provenance of the human material used. Of the 72% of respondents using images from external E-learning resources, 64% did not know the provenance of the human material in these resources. Some southern African anatomists considered anonymity as equivalent to informed consent. Regarding the acceptability of unclaimed bodies for online images, 37% of respondents were against the use of these bodies, while 20% indicated that it was acceptable. Personal internal moral conflict was acknowledged regarding the use of material from unclaimed bodies, particularly during crises such as the Coronavirus pandemic when digital resources were limited. DISCUSSION AND CONCLUSIONS Factors such as lack of awareness of provenance, the law in South Africa and using anonymity for consent, influence the ethical behaviour of southern African anatomists. Clear guiding principles would be of value for anatomists globally with respect to consent to the taking and distribution of images, and transparency on the source of the digital images provided in digital texts and online platforms. The establishment of both an oversight and ethics committee at institutions where digital imaging will be used is recommended.

Abstract
This article presents outcomes from a Workshop entitled "Bioarchaeology: Taking Stock and Moving Forward," which was held at Arizona State University (ASU) on March 6-8, 2020. Funded by the National Science Foundation (NSF), the School of Human Evolution and Social Change (ASU), and the Center for Bioarchaeological Research (CBR, ASU), the Workshop's overall goal was to explore reasons why research proposals submitted by bioarchaeologists, both graduate students and established scholars, fared disproportionately poorly within recent NSF Anthropology Program competitions and to offer advice for increasing success. Therefore, this Workshop comprised 43 international scholars and four advanced graduate students with a history of successful grant acquisition, primarily from the United States. Ultimately, we focused on two related aims: (1) best practices for improving research designs and training and (2) evaluating topics of contemporary significance that reverberate through history and beyond as promising trajectories for bioarchaeological research. Among the former were contextual grounding, research question/hypothesis generation, statistical procedures appropriate for small samples and mixed qualitative/quantitative data, the salience of Bayesian methods, and training program content. Topical foci included ethics, social inequality, identity (including intersectionality), climate change, migration, violence, epidemic disease, adaptability/plasticity, the osteological paradox, and the developmental origins of health and disease. Given the profound changes required globally to address decolonization in the 21st century, this concern also entered many formal and informal discussions.

Abstract
The Covid-19 pandemic has caused major changes in many sectors of society worldwide. The issue of medical education stands out since it had to adapt to the rules of social isolation, ensuing discussions about the computerization of teaching methodology, particularly in neuroanatomy. In particular, the latter showed satisfactory adaptability to new technologies and highly promising learning results. During this review, we aim to evaluate the current state of neuroanatomy teaching and evaluate the possibilities of incorporating technology into teaching–learning of human anatomy in a post-pandemic world.

Abstract
BACKGROUND The benefits of using cadaveric humans in surgical training are well documented, and knowledge of the latest endovascular techniques is essential in the daily practice of vascular surgeons. Our study explores the feasibility of an affordable human cadaveric model with pulsatile and heated antegrade perfusion for reliable and reproducible endovascular or surgical simulation. METHODS We undertook cannulation of 7 human cadavers embalmed in a saturated salt solution to create a left-to-right central perfusion with a heated solution, from the ascending thoracic aorta to the right atrium. To that end, we used surgically created carotidojugular and femorofemoral arteriovenous fistulas. Biomedical engineers designed a prototype pump for pulsatile circulation. We monitored invasive blood pressure and temperature. We used this model for training for endovascular thoracic aortic procedures and open vascular surgeries. RESULTS The prototype pump achieved a pulsatile flow rate of 4.7 L/min. Effective cadaveric perfusion was achieved for several hours, not only with an arterioarterial pathway but also with arteriovenous circulation. The arterial pressures and in situ temperatures accurately restored vascular functions for life-like conditions. This new model made it possible to successfully perform thoracic endovascular aortic repair, subclavian artery stenting and simulation of abdominal open vascular trauma management. The saturated salt solution method and a specifically designed pump improved cost competitiveness. CONCLUSION Endovascular simulation on human cadavers, optimized with the pulsatile and heated perfusion system, can be a dynamic adjunct for surgical training and familiarization with new devices. This reproducible teaching tool could be relevant in all surgery programs.

MacPherson E, Lisk K. The value of in-person undergraduate dissection in anatomical education in the time of Covid-19. ANATOMICAL SCIENCES EDUCATION 2022; 15:797-802. [PMID: 35523727 PMCID: PMC9348114 DOI: 10.1002/ase.2186] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Revised: 04/04/2022] [Accepted: 05/03/2022] [Indexed: 06/14/2023]
Abstract
While several innovative pedagogical practices have been developed and implemented in anatomy education since the onset of the coronavirus disease 2019 (Covid-19) pandemic, considering the value of in-person undergraduate dissection remains crucial. In this commentary, a human dissection course at the University of Toronto is used as an example to highlight the value of dissection for undergraduate learners in non-professional programs. In-person dissection allows for real life, anatomical variation, and supports the advancement of students' conceptual knowledge of the human body and visual-spatial abilities. Direct involvement with dissection during undergraduate training also provides students with an opportunity to practice and refine non-technical skills, such as communication and collaboration, while simultaneously promoting the development of students' professional identity formation. Further, dissection is a practical, hands-on experience that can provide students with insight into potential career aspirations related to anatomy and the health professions. It is suggested that as institutions veer from traditional pedagogical practices and evaluate how to best move forward post-pandemic, it is imperative that the value of undergraduate dissection is considered among new innovations in the field of anatomy.

Abstract
The aim of the study is to protect and preserve the cross-sectional diagnostic characteristics of the anatomy samples by using silicone plastination method, to examine them both macroscopically and microscopically, and to use them as an educational material. After the dissection procedures of 10 total sheep heads obtained from the slaughterhouse were completed, they were freshly frozen and sliced to prepare cross-sectional samples. Then, statistical analysis was performed after the colorimetric measurements. For microscopic examination, 30 brain samples were divided into three groups (Fresh-F, plastination-P, plastination/deplastination-P/D). Of the total brain samples, 20 were subject to routine plastination protocol. After the plastination/deplastination procedure, the changes occurring in cerebral histology were compared. In terms of tissue preservation, the effect of plastination and deplastination was examined using a light microscope. Plastinates subject to silicone plastination under room temperature were very similar to their natural appearance, and it was observed that they preserved their morphological features. Colour changes in the tissues were statistically evaluated. Volumetric shrinkages were observed as qualitative, especially in the brain. As a result of the evaluation done, it was seen that deplastination with toluene is not possible for the brain tissues. In addition, it was not possible to take cross sections of the plastinated tissues that were not deplastinated. On the contrary, findings regarding that deplastination with 5% sodium methoxide dissolved in methanol can allow microscopic examination in long-term preserved plastinated brain tissues were obtained.

Abstract
Anatomy Nights is an international public engagement event created to bring anatomy and anatomists back to public spaces with the goal of increasing the public’s understanding of their own anatomy by comparison with non-human tissues. The event consists of a 30-minute mini-lecture on the anatomy of a specific anatomical organ followed by a dissection of animal tissues to demonstrate the same organ anatomy. Before and after the lecture and dissection, participants complete research surveys designed to assess prior knowledge and knowledge gained as a result of participation in the event, respectively. This study reports the results of Anatomy Nights brain events held at four different venues in the UK and USA in 2018 and 2019. Two general questions were asked of the data: 1) Do participant post-event test scores differ from pre-event scores; and 2) Are there differences in participant scores based on location, educational background, and career. We addressed these questions using a combination of generalized linear models (R’s glm function; R version 4.1.0 [R Core Team, 2014]) that assumed a binomial distribution and implemented a logit link function, as well as likelihood estimates to compare models. Survey data from 91 participants indicate that scores improve on post-event tests compared to pre-event tests, and these results hold irrespective of location, educational background, and career. In the pre-event tests, participants performed well on naming structures with an English name (frontal lobe and brainstem), and showed signs of improvement on other anatomical names in the post-test. Despite this improvement in knowledge, we found no evidence that participation in Anatomy Nights improved participants’ ability to apply this knowledge to neuroanatomical contexts (e.g., stroke).

African Medical Educators and Anatomy Teachers' Perceptions and Acceptance of the Anatomage Table as an EdTech and Innovation: A Qualitative Study. ADVANCES IN MEDICAL EDUCATION AND PRACTICE 2022; 13:595-607.

Abstract
BACKGROUND This article presents a qualitative study of African anatomists and anatomy teachers on the Anatomage Table-a modern medical education technology and innovation, as an indicator of African anatomy medical and anatomy educators' acceptance of EdTech. The Anatomage Table is used for digital dissection, prosection, functional anatomy demonstration, virtual simulation of certain functions, and interactive digital teaching aid. MATERIALS AND METHODS Anatomy teachers [n=79] from 11 representative African countries, Ghana, Nigeria [West Africa], Ethiopia, Kenya, Rwanda [East Africa], Namibia [South Africa], Zambia [Southern Africa], Egypt [North Africa], and Sudan [Central Africa], participated in this study. Focus group discussions [FGDs] were set up to obtain qualitative information from stakeholders from representative institutions. In addition, based on the set criteria, selected education leaders and stakeholders in representative institutions participated in In-depth Interviews [IDIs]. The interview explored critical issues concerning their perceptions about the acceptance, adoption, and integration of educational technology, specifically, the Anatomage Table into the teaching of Anatomy and related medical sciences in the African continent. Recorded interviews were transcribed and analyzed using the Dedoose software. RESULTS African anatomists are generally technology inclined and in favor of EdTech. The most recurring opinion was that the Anatomage Table could only be a "complementary teaching tool to cadavers" and that it "can't replace the real-life experience of cadavers." Particularly, respondents from user institutions opined that it "complements the traditional cadaver-based approaches" to anatomy learning and inquiry, including being a good "complement for cadaveric skill lab" sessions. Compared with the traditional cadaveric dissections a majority also considered it less problematic regarding cultural acceptability and health and safety-related concerns. The lifelikeness of the 3D representation is a major factor that drives acceptability.

Abstract
Human dissection remains a cornerstone of the anatomy learning experience. However, the emotional response of students to the use of human remains for learning is influenced by a number of factors and is not always positive. Therefore, this study explored the students’ emotional response to and factors affecting their perceptions of the use of human remains for learning anatomy in a South African context. Four hundred and eighty of the 1538 health sciences students enrolled in human anatomy courses at the University of the Witwatersrand, South Africa during 2016 and 2017, completed a voluntary survey. The survey included closed and open-ended questions on students’ emotional responses, coping mechanisms and the factors that affected their perceptions of the use of human remains and dissection. Overall, the students had a positive emotional response. Their perceptions of dissection were affected in positive and negative ways by their religious and cultural beliefs. Feelings of gratitude and respect toward the cadaver were informed by belief systems. However, anxiety was caused by the delay of accepted sociocultural burial practices. Peer discussions were the preferred coping method, which may provide an approach for students to discuss how their beliefs influence their dissection experience.

Abstract
Andreas Vesalius initially accepted Galen's ideas concerning the rete mirabile in humans. In 1538, Vesalius drew a diagram of the human rete mirabile as a plexiform termination of the carotid arteries, where the vital spirit is transformed into the animal spirit, before being distributed from the brain along the nerves to the body. In 1540, Vesalius demonstrated the rete mirabile at a public anatomy, using a sheep's head (due to his nascent realization that he could not demonstrate this adequately in a human cadaver, potentially eliciting ridicule). By 1543, Vesalius had fully reversed himself, denied the existence of the rete mirabile in humans, and castigated himself for his prior failure to recognize this error in Galen's works. Vesalius nevertheless illustrated both the Galenic conception of the rete mirabile in humans and a schematic of the rete mirabile in ungulates. He intended the 1543 diagram of the human rete mirabile as an example of a mistake that resulted from Galen's overreliance on animals as models of human anatomy. However, in spite of Vesalius's intentions, for more than a century afterward, his figure was repeatedly and perversely plagiarized by advocates for Galenic doctrine, who misused it as a purportedly realistic representation of human anatomy and generally omitted the contrary opinions of Berengario da Carpi and Vesalius. The protracted use of stereotyped representations of the rete mirabile in extant printed illustrations provides tangible documentation of the stagnation in anatomical thought in the sixteenth and seventeenth centuries.

Abstract
The basic framework of the term "respect" is equality recognition. Students and teachers in academic institutions can have varying definitions of respect. Respect in the learning environment is critical for student success. This study aims to look into how students' perceptions of the human body in the anatomy lab and their respect for them can be used to promote ethical obligations, humanitarian principles, and their interrelationships. It is a descriptive, questionnaire-based study with 20 questions and a consent form that involves 250 students in the first year of MBBS. Using Microsoft Excel 2019, the data were collected, tabulated, and interpreted using descriptive statistics. The donor oath is a way to emphasize that the human body in front of them was once alive. The donor oath establishes the groundwork for future efforts to adapt existing frameworks for ethical decision-making and humanitarian values.

Abstract
Anatomical practice has arguably one of the most ethically challenging histories in the medical sciences. Among the oldest scientific disciplines in medicine, dissection of the human body for scientific purposes occurred as early as the third century Before the Common Era. Throughout the history of anatomical practice, human dissection has occurred in ways that cross the line from progressing medical science to violating the sanctity of the human body. The dissection of the human body creates ethical dilemmas which stem from the need for anatomical science to gain medical knowledge in juxtaposition with prevailing religious and moral views surrounding anatomy as a threat to the sanctity of the human body. This article examines the unethical history of human dissection throughout the ages and explores the rationale behind the unethical practices. In addition, this article explores imperative modern day ethical standards in anatomy including, the ethical handling of human bodies, respecting human life, and ensuring informed consent for dissection of bodies that are donated. Finally, this article explores the question of which ethical prism we should use when dealing with anatomy collections or works of the past. Learning both the history of unethical practices in anatomy and the rationale behind them is imperative so that the discipline can prepare for an ethical, diverse, and inclusive future. This article provides a foundation for understanding the evolution of ethics in anatomical practice and is a valuable resource for students and anatomists alike.

Abstract
Background: Myths and religion are belief systems centered around supernatural entities that attempt to explain the observed world and are of high importance to certain communities. The former is a collection of stories that belong to a cultural tradition and the latter are organized faiths that determine codes of ethics, rituals and philosophy. Deities or monstrous creatures in particular act as archetypes instructing an individual’s conduct. References to them in Greek mythology and Christianity are frequently manifested in the modern neurosurgical vernacular. Methods: A review of the medical literature was performed using the PubMed and MEDLINE bibliographic databases. Publications from 1875 to 2021 related to neurosurgery or neuroanatomy with the medical subject headings (MeSH) terms mythology, religion, Christianity and Catholicism were reviewed. References pertaining to supernatural beings were classified to either a deity or a monstrosity according to their conventional cultural context. Results: Twelve narratives associated with neurosurgery were identified, nine relating to Greek mythology and three associated with the Christian-Catholic faith. Eight accounts concerned deities and the remaining with monstrous creatures. Conclusion: This article explores the etymology of commonly utilized terms in daily neurosurgical practice in the context of mythology and religion. They reveal the ingenuity and creativity of early pioneers who strived to understand the brain.

Abstract
BACKGROUND Anatomy education in US medical schools has seen numerous changes since the call for medical education reform in 2010. The purpose of this study was to survey US medical schools to assess recent trends in anatomy education, the impact of the COVID-19 pandemic on anatomy teaching, and future directions of medical school anatomy curricula. METHODS We sent a 29-item survey to anatomy course directors of 145 AAMC-associated allopathic medical schools inquiring about their schools' anatomy curricula. The survey contained objective discrete questions concerning the curricula changes preceding COVID-19 and those directly related to COVID-19. We also asked subjective and open-ended questions about the impact of COVID-19 and future directions of anatomy education. RESULTS A total of 117/143 course directors (82%) completed the survey. Most schools (60%) reported a major change to their anatomy course within the past five years, including a decrease in total course time (20%), integration of anatomy into other courses (19%), and implementation of a "flipped classroom" (15%) teaching style. Due to COVID-19, there was a decrease in the fraction of course time dedicated to "hands-on" learning (p < 0.01) and teaching of clinical correlates (p = 0.02) and radiology (p < 0.01). Most course directors (79%) reported that COVID-19 had a negative impact on quality of learning due to decreased interactive or in-person (62%) learning and lack of dissection (44%). Incorporation of virtual-reality applications or 3D anatomy software (23%) and a decrease in cadaver dissection (13%) were the most common future anticipated changes. CONCLUSION The constraints conferred by COVID-19 highlight the importance of maximizing interactive learning in the discipline of anatomy. In an era of social distancing and decreased emphasis on conventional anatomy dissection, adaptations of new technologies and teaching modalities may allow for traditional educational rigor to be sustained.

Abstract
Within the discipline of anatomical education, the use of donated human cadavers in laboratory-based learning activities is often described as the 'gold standard' resource for supporting student understanding of anatomy. Due to both historical and educational factors, cadaveric dissection has traditionally been the approach against which other anatomy learning modalities and resources have been judged. To prepare human donors for teaching purposes, bodies must be embalmed with fixative agents to preserve the tissues. Embalmed cadavers can then be dissected by students or can be prosected or plastinated to produce teaching resources. Here, we describe the history of cadaveric preservation in anatomy education and review the practical strengths and limitations of current approaches for the embalming of human bodies. Furthermore, we investigate the pedagogic benefits of a range of established modern embalming techniques. We describe relevant cadaveric attributes and their impacts on learning, including the importance of colour, texture, smell, and joint mobility. We also explore the emotional and humanistic elements of the use of human donors in anatomy education, and the relative impact of these factors when alternative types of embalming process are performed. Based on these underpinnings, we provide a technical description of our modern Newcastle-WhitWell embalming process. In doing so, we aim to inform anatomy educators and technical staff seeking to embalm human donors rapidly and safely and at reduced costs, while enhancing visual and haptic tissue characteristics. We propose that our technique has logistical and pedagogic implications, both for the development of embalming techniques and for student visualisation and learning.

Abstract
The removal of petroclival meningiomas (PMs) is considered a neurosurgical challenge due to the critical mobilization of key neurovascular structures. Limited knowledge about the benefits of operating on patients with PMs using the combined presigmoid-subtemporal approach (CPSA) in a semi-sitting position has precluded its generalizability. We report on ten patients with PMs operated in a semi-sitting position using CPSA. We remark that before the surgical approach was accomplished in our group of patients, the CPSA via semi-sitting position was conducted and standardized in six adult cadaveric heads. The neuroanatomic dissections made in cadavers allowed us to confidently use CPSA in our set of patients. There were no comorbidities, perioperative complications, or deaths associated with the surgical procedure. CPSA via a semi-sitting position can be considered a safe approach to remove PMs.

Abstract
BACKGROUND Human cadavers are an essential component of anatomy education. However, access to cadaveric specimens and laboratory facilities is limited in most parts of the world. Hence, new innovative approaches and accessible technologies are much needed to enhance anatomy training. OBJECTIVE To provide a practical method for 3-dimensional (3D) visualization of cadaveric specimens to maximize the utility of these precious educational materials. METHODS Embalmed cadaveric specimens (cerebrum, brain stem, and cerebellum) were used. The 3D models of cadaveric specimens were built by merging multiple 2-dimensional photographs. Pictures were taken with standard mobile devices (smartphone and tablet). A photogrammetry program (Qlone®, 2017-2020, EyeCue Vision Technologies Ltd, Yokneam, Israel), an all-in-one 3D scanning and augmented reality technology, was then used to convert the images into an integrated 3D model. RESULTS High-resolution 360-degree 3D models of the cadaveric specimens were obtained. These models could be rotated and moved freely on different planes, and viewed from different angles with varying magnifications. Advanced editing options and the possibility for export to virtual- or augmented-reality simulation allowed for better visualization. CONCLUSION This inexpensive, simple, and accessible method for creating 360-degree 3D cadaveric models can enhance training in neuroanatomy and allow for a highly realistic surgical simulation environment for neurosurgeons worldwide.

Abstract
The law of Non-Original Malappropriate Eponymous Nomenclature (NOMEN) states that no phenomenon is named after its discoverer. However, eponymous terms are rife in the anatomical and medical literature. In this viewpoint commentary, the authors discuss the history of anatomical eponyms, explain the additional cognitive load imposed by eponyms that can negatively impact student learning and explore the view that eponyms are "pale, male and stale" in the socially conscious 21st century. The authors probe two of the most common arguments used to keep eponyms in anatomy education: (1) clinicians use them because they are easy, and (2) eponyms remind us of anatomy's history. Educators, clinicians and students need to work together to progress this movement and bring a modern lens to this discussion. Based on the arguments presented in this commentary, the authors propose that eponyms should be removed from anatomy curricula, textbooks and have no place in the anatomy classroom.

Abstract
One of the most widely used solutions to fix and preserve organic tissues is formaldehyde, despite reservations regarding its toxicity and the fact that formaldehyde-embalmed bodies lose their original characteristics. Anatomy laboratories have been replacing formaldehyde with solutions that retain the characteristics of fresh tissue. For this purpose, alternative solutions with a very low concentration of formaldehyde or without any formaldehyde have been analyzed. The objective of this study was to compare biometry, coloration, haptic properties, and bacterial load on animal specimens (pig kidneys) embalmed with formaldehyde, and with Chilean Conservative Fixative Solution with and without formaldehyde (formaldehyde chCFS and formaldehyde-free chCFS). Also, the perception of health and biological science students toward specimens treated with different solutions was assessed. The results indicated that there were no significant differences in specimens' retraction, or bacterial load. Students showed a preference for organs embalmed in formaldehyde chCFS and formaldehyde-free chCFS; indicating that with these treatments they could better visualize structures and that the prosections had greater flexibility and the colors were more similar to those of fresh tissue. Additionally, students recommended the material embalmed in formaldehyde chCFS and formaldehyde-free chCFS for anatomy learning. In contrast, students indicated that formaldehyde-fixation negatively affected their practical experience. In conclusion, embalming with formaldehyde chCFS or formaldehyde-free chCFS provides an advantageous practical experience over the use of formaldehyde and may be an alternative to replace the use of formaldehyde in anatomy laboratories.

Abstract
Dissection and human specimens study remain the gold standard method for teaching anatomy. Due to the increasing health science courses in Brazil, the traditional way of obtaining bodies for scientific purposes, the unclaimed ones, became insufficient. In addition, this source is no longer ethically appropriate according to anatomists. In order to maintain the teaching quality, the Federal University of Juiz de Fora (UFJF) in Brazil, inspired by successful initiatives around the world, created a body donation program; Sempre Vivo. Besides the bureaucratic difficulty faced during its regulation, the implementation of a body donation program requires special attention regarding the religiosity, culture and uniqueness of the city's inhabitants. Informing people can demystify the process, avoid prejudice and increase the number of donors. In this way, an outreach project was designed to publicize Sempre Vivo and raise public awareness. In the first six years, Sempre Vivo reached the mark of 64 registered donors and seven bodies received. The donor’s profile corresponds to female (70.3%), 57 years of age, retired (50.8%), spiritist (53.1%) and with 12 years or more of formal education (90.6%). Considering that the UFJF has not received unclaimed bodies for ten years, the program was considered satisfactory up to this level and, in the future, it may be the exclusive source of anatomical specimens. The description of the creation and the publicizing of Sempre Vivo, the overcome challenges, as well as the donors’ profile, may encourage and facilitate the foundation of similar programs in Brazil and abroad.

Abstract
As European anatomical teaching developed in the middle ages, anatomists found themselves balanced between the educational and judicial systems. Dissection was associated with the final stages of legal prosecutions and the supply of bodies was severely limited. Driven by increasing student demand for dissection, anatomists found themselves pushed to explore alternative routes for body supply. This led to association with the developing profession of grave robber, body snatchers, and even murderers. Keen to protect themselves from increasing vulnerability to legal prosecution, the eminent anatomists of the United Kingdom pushed for government legislation to provide a supply of cadaveric material for education. This article looks at the development of the Anatomy legislation in the United Kingdom in 1832. By highlighting three events in the early 1800s, it demonstrates that the development of the legislation was for addressing the concerns of the anatomists rather than any ethical concerns about the cadaveric supply. The poorest in society were used to develop the medical understanding of the more wealthy before, during, and after the introduction of the legislation. The first event made the anatomists criminal liable for body supply while the latter two events linked anatomists with murderers. The increasing demand for legislation to provide a supply of cadaveric material released the anatomists from the financial burden of dealing with grave robbers while still allowing dissection tables to be supplied with the poorest in society.

Abstract
OBJECTIVE To discuss the historical relevance of the original illustrations and descriptions of the facial nerve during the Italian Renaissance (ca. late 14th to early 17th centuries). MATERIAL AND METHODS Graphic and textual information related to facial nerve discoveries were harvested from the works of the study period's anatomists, with special attention to those of Leonardo da Vinci, Andreas Vesalius, Gabrielle Falloppio, and Bartolomeo Eustachio. The importance of Galen's anatomical works as a guide to these discoveries is discussed. CONCLUSION The reviewed texts and the illustrations therein contained provided sufficient information to establish a sequence of discoveries that resulted in a near-modern knowledge of the anatomy of the facial nerve and the basis to comprehend its function.

Abstract
Present day scenario regarding epistemological methods in anatomy is in sharp contrast to the situation during ancient period. This study aimed to explore the evolution of epistemological methodologies in anatomy across centuries. In ancient times Egyptian embalmers acquired anatomical knowledge from handling human bodies and likewise anatomical studies in India involved human dissection. Ancient Greeks used theological principles-based methods, animal dissection and human dissection in practice of anatomy. Human dissection was also practiced in ancient China for gaining anatomical knowledge. Prohibition of human dissection led to use of animal dissection in ancient Rome and the trend continued in Europe through Middle Ages. Epistemological methods used by Muslim scholars during Middle Ages are not clearly chronicled. Human dissection returned as primary epistemological method in Renaissance Europe and empirical methods were reinstated after ancient period in human dissection during 16th century. The situation further improved with introduction of pragmatic experiment based approach during 17th century and autopsy-based methods during 18th century. Advances in anatomical knowledge continued with advent of microscope-based methods and emergence of anatomical sections in practice of human dissection in 19th century. Introduction of human observational studies, medical imaging, and molecular methods presented more options in terms of epistemological methods for investigating the human body during 20th century. Onset of 21st century has witnessed dominance of technology-based methods in anatomy. Limited emphasis on ethics in epistemological methodologies since antiquity is a dark aspect of otherwise an eventful evolutionary journey but recent developments are in positive direction.

Abstract
Over the last four millennia, the discipline of anatomy and its relationships with medicine and society have evolved dramatically. Human dissection, the perennial tool for anatomical discovery and education, has both guided this evolution and matured alongside it. Soon after the first cadaveric dissections recorded in ancient Greece, China, India, and Persia, clear endorsements of its practice fell largely silent in the anatomical record for 1,500 years before reappearing in Europe at the dawn of the Renaissance. Between the 13th and 18th centuries CE, the performance of anatomical dissection became a popular form of education and public entertainment, and the demand for human cadavers steadily increased among European anatomical schools while supply remained limited by legal statute. This gave rise to an informal group of amateur and professional body snatchers called the Resurrectionists and, later, inspired the Anatomy Act of 1832 CE. In the 20th and 21st centuries CE, voluntary body bequeathal programs have enabled the practice of human dissection to continue in academic centers as a cornerstone of anatomical education, now with a newfound focus on the development of affective skills. This article provides an abridged account of anatomy's development, highlighting key moments in its growth, the valuable contributions of many different societies to the discipline, and the important roles of several luminary anatomists of antiquity. Within the broader context of this history, it offers an overview of anatomical dissection's evocative past, spanning from its inception to its present-day practice.

Abstract
Forensic odontology is a specialty of dental sciences that deals with dental evidence in the interest of the justice system. The science of autopsy has been developing from the ancient times even before the popularization of general medicine. The objective of a medico-legal autopsy is to identify significant clues for an ongoing forensic investigation. However, in certain circumstances, it is difficult to conduct an oral examination owing to the anatomic location of the oral cavity. The onset of rigor mortis after death poses further complications. Thus, skillful and sequential dissections of the oral and para-oral structures are required to expose the dentition. Dental autopsy includes incisions and resection of the jaw for the detailed examination of the oral cavity. The procedure involves various modes of examination, including visual and radiographic, which help in human identification in forensic investigation. The present paper provides an overview of the various methods of dental autopsy.

Abstract
Deceased human bodies are donated for education and research. Informed consent has become the standard for research on the living. A question could be asked on how informed are the donors and their families about the process before this generous gift is given. The aim of this study is to evaluate and compare the published donation forms used by body donation programs in the United States and assess them according to the guidelines published by the American Association of Clinical Anatomists. The findings of this study shows that the level of information given to donors and families, before consenting to whole body donation, varies greatly throughout the United States. Many of the forms fail to include the recommendations made by professional societies. Additional information needs to be added to whole body donation forms to better inform donors and families about the donation process, what happens to the body, and the final disposition of the bodies once studies are completed. Overall, it was concluded that in some cases consent is being obtained but much more needs to be done before institutions can claim to obtain informed consent.

Abstract
Raymond de Vieussens was an exemplary anatomist who made seminal contributions in the field of cardiology. During initial part of his academic career, he adopted human dissection based experiments as medium of his research. This was in accordance with prevailing trend among anatomists during 17th century. He discovered the presence of tiny venous tributaries communicating between cardiac veins and chambers of heart (ducti carnosi/venae cordis minimae). He reported the existence of a collateral circulatory pathway between right and left coronary arterial systems (Vieussens arterial ring). He was the first to note the valve at the junction of great cardiac vein and coronary sinus (valve of Vieussens) and the prominent oval margin of the fossa ovalis (Vieussens Annulus). All his findings were associated with considerable clinical significance as evidenced in literature that followed. Vieussens accurately demonstrated the three-layered orientation of myocardium and gave a precise description of coronary arteries and their branches. At the onset of 18th century, buoyed by royal patronage from King Louis XIV of France, the second half of Vieussens illustrious career was defined by pathologic anatomy (autopsy based) and anatomo clinical correlations. This was a new trend initiated by Vieussens in anatomical research and was later adopted as a signature method by anatomists of 18th century. As a true connoisseur of cardiologic anatomy, Vieussens accurately charted the anatomo clinical correlations of cardiac tamponade, mitral stenosis and aortic regurgitation. His contributions were pivotal elements in metamorphosis of cardiology as a robust discipline of medicine in modern times.

Background Human anatomy has historically been a cornerstone in medical education and is special in that it uses human remains kept in various anatomical facilities like a morgue, gross anatomy laboratory, or museums for instruction and research. While serving knowledge advancement facilitating clinical practice and research, human cadaver handling, and usage at all levels, such as cadaver sourcing, transportation, storage, preservation, dissection, and final disposal deserves in return the utmost respect. In Ethiopia, even though there is not enough information on when, where, and by whom the first cadaver dissection was conducted, dissection is being conducted in many of its medical schools. Despite ethical necessity surrounding human body usage in every anatomical setting, there is still ethical and legal uncertainty due to several challenging barriers which is severe in developing nations including Ethiopia. The aim of this study is, therefore, to assess ethical practices of handling and usage of the human body to promote, in the near future, formulation and implementation of acceptable, respectful, and ethical guidelines for the anatomy dissection laboratories and related settings in Ethiopia. Methods A multicentered cross-sectional study was used at selected anatomy facilities of eight Ethiopian medical schools. The collected data through structured questionnaires and checklists were cleaned, preset and entered in to SPSS version 20 for analysis. Internal consistency and reliability were measured by using Cronbach’s alpha. Results The study result showed vivid human body ethical breaches that ranged from lack of power by anatomy unit to oversee the process during sourcing, transportation, embalming, caring, and dissection of cadavers in the anatomy laboratories to student’s mistreatment of cadavers. Conclusion In addition to lack of compliance due to lack of standard ethical guidelines or policies regarding human body usage, the compliance-based professional development is also nonexistent. The ethical way of body sourcing is through body donation; however, in Ethiopia, anatomy teaching exclusively depends on unclaimed bodies. Using a body for dissection that is solely sourced unethically may generate a negative emotional sense of life for anatomy instructors, technical assistants, morticians, and medical students. We inspire better provision of moral and ethical exercise with the good practice concerning the human body through recognizing the humanity and uniqueness of the deceased person. The results of this study serve as a serious condemnation of practices in Ethiopian anatomy facilities and we urge the Anatomical Society of Ethiopia to play its part in changing the present practices related to ethical and legal uncertainty of the human body usage.

Abstract
Human body dissection is the traditional instructional method for anatomy education worldwide, providing a kinaesthetic learning experience that is often challenging to achieve with other teaching techniques. However, due to lack of body donation programs in Middle Eastern medical schools, dead bodies are imported from abroad. Since literature suggests that the body shortage is influenced by reluctance to donate one's body, this study aimed to determine the perceptions of faculty, staff, and students regarding body donation for educational purposes at a new Dubai-based medical school. An online dually translated questionnaire was administered to the target population (322), of which 150 participants representative of faculty, staff, and students, responded. Although 111 (74.0 %) of participants considered body donation to be appropriate for educational and research purposes, only 44 (29.3 %) of participants expressed willingness to donate their bodies. Reluctance to donate 106 (70.7 %) appeared to be mostly influenced by religion, psychological barrier, and familial reasons. The emergence of four themes (i.e., resource, barrier, humanitarian, and awareness) and the identification of a potential donor group within the group that was willing to donate provided insight into the level of awareness within the university community. Furthermore, such findings may assist to establish future body donation programs and strategize recruitment approaches, especially when there is an ensuing dearth of anatomical donations.

Abstract
This article explores the effects of the coronavirus disease 2019 (Covid-19) pandemic on the evolution of both physical and digital cadavers within the unique ecosystem of the anatomy laboratory. A physical cadaver is a traditional and established learning tool in anatomy education, whereas a digital cadaver is a relatively recent phenomenon. The Covid-19 pandemic presented a major disturbance and disruption to all levels and types of education, including anatomy education. This article constructs a conceptual metaphor between a typical anatomy laboratory and an ecosystem, and considers the affordances, constraints, and changing roles of physical and digital cadavers within anatomy education through an ecological lens. Adaptation of physical and digital cadavers during the disturbance is analyzed, and the resiliency of digital cadaver technology is recognized. The evolving role of the digital cadaver is considered in terms of increasing accessibility and inclusivity within the anatomy laboratory ecosystem of the future.

Abstract
The understanding of epilepsy has been in progressive evolution since Antiquity, with scientific advances culminating in the last few decades. Throughout history, epilepsy was plagued by mystical misconceptions involving either demonic possessions, witchcraft, or divine interventions. This has frequently altered or even halted any real progress in its scientific understanding or its social perception. This metaphysical context is also at the core of the stigma revolving around this condition, some of which still lingering today. This review explores the origins of these mystical beliefs, and describes the chronological evolution of epilepsy from mysticism to science across different civilizations and eras.

Abstract
Anatomical education and surgical training with cadavers are usually considered an appropriate method of teaching, above all for all surgeons at various levels. Indeed, in such a way they put into practice and exercise a procedure before performing it live, reducing the learning curve in a safe environment and the risks for the patients. Really, up to now it is not clear if the nonuse of the cadavers for anatomical education and surgical training can have also forensic implications. A substantial literature research was used for this review, based on PubMed and Web of Science database. From this review, it is clear that the cadaveric training could be considered mandatory, both for surgeons and for medical students, leading to a series of questions with forensic implications. Indeed, there are many evidences that a cadaver lab can improve the learning curve of a surgeon, above all in the first part of the curve, in which frequent and severe complications are possible. Consequently, a medical responsibility for residents and surgeons which perform a procedure without adequate training could be advised, but also for hospital, that has to guarantee a sufficient training for its surgeons and other specialists through cadaver labs. Surely, this type of training could help to improve the practical skills of surgeons working in small hospitals, where some procedures are rare. Cadaver studies can permit a better evaluation of safety and efficacy of new surgical devices by surgeons, avoiding using patients as ≪guinea pigs≫. Indeed, a legal responsibility for a surgeon and other specialists could exist in the use of a new device without an apparent regulatory oversight. For a good medical practice, the surgeons should communicate to the patient the unsure procedural risks, making sure the patients' full understanding about the novelty of the procedure and that they have used this technique on few, if any, patients before. Cadaver training could represent a shortcut in the standard training process, increasing both the surgeon learning curve and patient confidence. Forensic clinical anatomy can supervise and support all these aspects of the formation and of the use of cadaver training.

Abstract
In Italy, recent legislation (Law No. 10/2020) has tuned regulations concerning the donation of one's postmortem body and tissues for study, training, and scientific research purposes. This study discusses several specific issues to optimise the applicability and effectiveness of such an important, novel regulatory setting. Critical issues arise concerning the learners, the type of training and teaching activities that can be planned, the position of academic anatomy institutes, the role of family members in the donation process, the time frame of the donation process, the eligibility of partial donation, or the simultaneous donation of organs and tissues to patients awaiting transplantation. In particular, a universal time limit for donations (i.e., one year) makes it impossible to plan the long-term use of specific body parts, which could be effectively preserved for the advanced teaching and training of medical students and surgeons. The abovementioned conditions lead to the limited use of corpses, thus resulting in the inefficiency of the whole system of body donation. Overall, the donors' scope for the donation of their body could be best honoured by a more flexible and tuneable approach that can be used on a case-by-case basis. Furthermore, it is deemed necessary to closely monitor the events scheduled for corpses in public nonacademic institutions or private enterprises. This paper presents useful insights from Italian anatomists with the hope of providing inspiration for drafting the regulations. In conclusion, this paper focuses on the critical issues derived from the recently introduced Italian law on the donation and use of the body after death and provides suggestions to lawmakers for future implementations.

Abstract
BACKGROUND The advancements of technologies have developed anatomical education into a new era. The study aims to assess medical students' performance and overall satisfaction who used the anatomage table and plastinated specimens for the teaching and learning anatomy courses. METHODS A cross-sectional study was conducted on students of the first-year college of medicine at Imam Mohammad Ibn Saud Islamic University (IMSIU). Students were randomly distributed equally into three groups A, B, and C. All groups were taken two sessions of lectures for one hour each. Each lecture was followed by a practical session of two hours. Group A learned with the "Anatomage" table and Group B learned the same topics on plastinated specimens. Group C was learning on both plastinated specimens and the "Anatomage" table. The objective structured practical examination was given to all students immediately after the practical sessions. A structured questionnaire was given to each group to determine the students' views on the educational methods. RESULTS There was a statistically significant difference between the means of the total scale scores for the three teaching methods, where students expressed a higher attitude towards both strategies for teaching in comparison to the anatomage table and plastinated models for teaching, where the means were 18±4.4, 18.3±4.6, 20.4±5.6, respectively, F=12.6 and P=0.0001. There were higher and positive students' attitudes regarding the five statements in favor of both models teaching compared to anatomage table and plastinated model teaching alone. CONCLUSION The first-year medical students have valued the combination of anatomage table and plastinated prosections in learning and assessing anatomy education at the undergraduate level. The advantages outweigh the limitation of these educational tools.

Abstract
As post-secondary education migrates online, developing and evaluating new avenues for assessment in anatomy is paramount. Three-dimensional (3D) visualization technology is one area with the potential to augment or even replace resource-intensive cadaver use in anatomical education. This manuscript details the development of a smartphone application, entitled "Virtual Reality Bell-Ringer (VRBR)," capable of displaying monoscopic two-dimensional (2D) or stereoscopic 3D images with the use of an inexpensive cardboard headset for use in spot examinations. Cadaveric image use, creation, and pinning processes are explained, and the source code is provided. To validate this tool, this paper compares traditional laboratory-based spot examination assessment stations against those administered using the VRBR application to test anatomical knowledge. Participants (undergraduate, n = 38; graduate, n = 13) completed three spot examinations specific to their level of study, one in each of the modalities (2D, 3D, laboratory) as well as a mental rotation test (MRT), Stereo Fly stereotest, and cybersickness survey. Repeated measures ANCOVA suggested participants performed significantly better on laboratory and 3D stations compared to 2D stations. Moderate to severe cybersickness symptoms were reported by 63% of participants in at least one category while using the VRBR application. Highest reported symptoms included: eye strain, general discomfort, difficulty focusing, and difficulty concentrating. Overall, the VRBR application is a promising tool for its portability, affordability, and accessibility. Due to reported cybersickness and other technical limitations, the use of VRBR as an alternative to cadaveric specimens presents several challenges when testing anatomy knowledge that must be addressed before widespread adoption.

Abstract
This manuscript summarizes presentations of a symposium on key considerations in design of biomechanical models at the 2019 Basic Science Focus Forum of the Orthopaedic Trauma Association. The first section outlines the most important characteristics of a high-quality biomechanical study. The second section considers choices associated with designing experiments using finite element modeling versus synthetic bones versus human specimens. The third section discusses appropriate selection of experimental protocols and finite element analyses. The fourth section considers the pros and cons of use of biomechanical research for implant design. Finally, the fifth section examines how results from biomechanical studies can be used when clinical evidence is lacking or contradictory. When taken together, these presentations emphasize the critical importance of biomechanical research and the need to carefully consider and optimize models when designing a biomechanical study.

Abstract
The most distant roots of neuroanatomy trace back to antiquity, with the first human dissections, but no document which would identify the thalamus as a brain structure has reached us. Claudius Galenus (Galen) gave to the thalamus the name 'thalamus nervorum opticorum', but later on, other names were used (e.g., anchae, or buttocks-like). In 1543, Andreas Vesalius provided the first quality illustrations of the thalamus. During the 19th century, tissue staining techniques and ablative studies contributed to the breakdown of the thalamus into subregions and nuclei. The next step was taken using radiomarkers to identify connections in the absence of lesions. Anterograde and retrograde tracing methods arose in the late 1960s, supporting extension, revision, or confirmation of previously established knowledge. The use of the first viral tracers introduced a new methodological breakthrough in the mid-1970s. Another important step was supported by advances in neuroimaging of the thalamus in the 21th century. The current review follows the history of the thalamus through these technical revolutions from Antiquity to the present day.

Dissection versus Prosection: A Comparative Assessment of the Course Experiences, Approaches to Learning, and Academic Performance of Non-medical Undergraduate Students in Human Anatomy. ANATOMICAL SCIENCES EDUCATION 2021; 14:184-200. [PMID: 32539226 DOI: 10.1002/ase.1993] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/25/2019] [Revised: 05/29/2020] [Accepted: 06/07/2020] [Indexed: 06/11/2023]
Abstract
Many institutions rely upon prosection-based laboratories as more resource-efficient and time-effective alternatives to traditional cadaver dissection for human anatomy education. To facilitate growing enrollment numbers despite resource limitations, the University of Guelph (a non-medical institution) introduced a modified "stepwise" prosection-based laboratory cohort to supplement a dissection-based course. In this design, all students attended the same lectures, but those in the dissection-based cohort learned by performing regional dissections and students in the prosection-based cohort studied from those dissections. Prosection students thereby witnessed a "slow reveal" of structures throughout the course. This study compared the perceived course experiences, student approaches to learning, and academic performance between the two groups. Multiple linear regression analyses were used to isolate the effect of the laboratory environment on student approaches to learning and academic performance from demographic and situational covariates. Both groups reported positive course experience ratings and high average final grades that were not statistically dissimilar (P > 0.05), increased reliance on deep approaches to learning (P = 0.002), and decreased reliance on surface approaches to learning (P = 0.023). When controlling for covariates, participation in dissection had small but statistically significant positive associations with deep approaches to learning (P = 0.043), performance on laboratory oral assessments (P < 0.001), and average final grades (P = 0.039). Ultimately, both designs promoted meaningful learning and desirable performance outcomes, indicating that both dissection and stepwise prosection have the potential to facilitate high quality human anatomy instruction.
