The evolution of epistemological methodologies in anatomy: From antiquity to modern times

Ethical concerns surrounding artificial intelligence in anatomy education: Should AI human body simulations replace donors in the dissection room?

The potential effects of artificial intelligence (AI) on the teaching of anatomy are unclear. We explore the hypothetical situation of human body donors being replaced by AI human body simulations and reflect on two separate ethical concerns: first, whether it is permissible to replace donors with AI human body simulations in the dissection room when the consequences of doing so are unclear, and second, the overarching ethical significance of AI use in anatomy education. To do this, we highlight the key benefits of student exposure to the dissection room and body donors, including nontechnical, discipline-independent skills, awareness and interaction with applied bioethics, and professional identity formation. We suggest that the uniqueness of the dissection room experience and the importance of the key benefits accompanying this exposure outweigh the potential and so far unknown benefits of AI technology in this space. Further, the lack of engagement with bioethical principles that are intimately intertwined with the dissection room experience may have repercussions for future healthcare professional development. We argue that interaction with body donors must be protected and maintained and not replaced with AI human body donor simulations. Any move away from this foundation of anatomy education requires scrutiny. In light of the possible adoption of AI technologies into anatomy teaching, it is necessary that medical educators reflect on the dictum that the practice of healthcare, and anatomy, is a uniquely human endeavor.

Public human dissection and societal connect of anatomical sciences: A glorious association in the past but ethically forbidden practice at present

Under the futuristic vision of anatomical sciences, a strong societal connection is mandatory. The anatomical practice experienced robust societal participation through public human dissection from the 16th century onward. With a perspective to explore the intersection of spirituality with anatomy, the present study analyzed this momentous period. From a spiritual perspective, the study also reflects on two relevant but presently uncoupled entities of public human dissection and societal connection through the prism of current regulations. Strong representation from the general public during public human dissection was primarily driven by spiritual proclivity and an endorsement from religious authorities. To regulate large gatherings and maintain academic sanctity, anatomical theaters emerged as dedicated spaces for such a merger. With time and growing financial support, the theaters transformed from temporary structures to elaborate architectural marvels, further propelling already robust societal connections associated with the practice. Nevertheless, a confluence of multiple factors led to the violation of spiritual principles and a consequent decrease in societal participation from the early 18th century, eventually culminating in the demise of such spectacle. Presently, public human dissection-when done-is mostly conducted for commercial gains and in contravention of ethical norms. It is against the essence of spirituality and harbors a bleak prospect for societal connection. Contrastingly, measures adopted to promote societal participation (mostly related to body donation) were quite effective and followed the principles of spirituality. Societal connections served anatomy in the past and can lead to its advancement if approached through a righteous path.

Evolution of staining methods in neuroanatomy: Impetus for emanation of neuron doctrine during the turn of 20th century

The nervous system is distinctive as compared to other tissue systems in human body owing to intricate structural organization. Histological studies played a key role in unveiling complex details of nervous tissue. However, the process of developing suitable staining method for nerve cells was arduous and spanned across almost half a century. The present study explored details of the journey involving quest for propitious staining method in neuroanatomy culminating in promulgation of neuron doctrine at the onset of 20th century. Initial efforts involving hematoxylin (including its diverse modifications) and subsequent adoption of analogous dye-based stains (like Nissl's method) had limited success in visualization of different parts of a nerve cell and structural details of nervous tissue. This was due to inability of dye-based stains to penetrate the connective tissue sheath of nervous tissue. Eventually, advent of metallic stains in form of silver impregnation method (Golgi stain), reduced silver impregnation method with gold stain (Cajal's stain) and silver carbonate staining method of Río-Hortega unraveled the structure of nervous tissue. The evolution of staining methods catalyzed the refinement of theories pertinent to constitution of nervous tissue. Golgi's staining led to emergence of reticular theory (neurons exist as a network) and Nissl's staining was the basis of the concept of Nervösen Grau (nerve cells and glial cells are embedded in mass of gray matter). Finally, Cajal's staining method successfully elucidated the complex anatomy of nerve terminals and resulted in emanation of neuron doctrine (neurons exists as individual units with adjacent connections).

Responsible research in the practice of anatomy: Attributes relevant to body donors and human tissues sourced from them

Responsible Research involves setting moral examples before fellow academicians and the society as a whole. The concept of Responsible Research applies appropriately to ethical sourcing and handling of human tissues. The present study was undertaken to analyze present situation regarding implementation of attributes of Relevant Research in relation to body donors in anatomical research. A literature search of relevant, peer-reviewed, published articles was undertaken from indexed databases (Medline & PubMed, Scopus, Embase, CINAHL Plus, Web of Science and Google Scholar) for this study. The following attributes of Responsible Research were identified for possible intervention: the fact that research was conducted on human tissues from body donors and details regarding ethical handling thereof may be explicitly mentioned in method section; expression of gratitude towards body donors by authors may be included in acknowledgement section; editor's and publisher's note in support of adoption of attributes of Responsible Research may be included in published research. Adherence to best practices in terms of ethical guidelines requires anatomists to embrace a responsible approach in research from an inclusive perspective. Accordingly, practice of acknowledging the body donors may be nurtured and augmented to include the anonymised dead (human tissues from unclaimed bodies and unknown source) provided the research protocol received clearance from authorities concerned with ethical scrutiny. Moreover, adoption of the practice in review articles will enhance the boundaries of Responsible Research in anatomical science. Thus, few recommendations are proposed as epilogue for effectual implementation of the notion floated in present study.

First patient project: Engaging pathology through the donor dissection experience and its role in professionalism

The peer-reviewed anatomical education literature thoroughly describes the benefits and drawbacks of donor dissection. Gross anatomy laboratory environments utilizing donor dissection are generally considered to be a premier environment where students foster non-traditional discipline-independent skills (NTDIS), including the acquisition of professionalism, empathy, resilience, emotional intelligence, and situational awareness. Therefore, this IRB-approved study explored the impact of a formal humanism and pathology thread, the first patient project (FPP), on the personal and professional development of pre-professional undergraduate students in a gross anatomy dissection-based course. Five reflections from each student were collected across four cohorts (n = 74 students, 370 reflections). A post-course questionnaire collected data on student perceptions of the project. The framework method was used to analyze reflection and free response data and descriptive statistics were performed on Likert-style items using Excel. Three themes were identified to encompass the impacts of the FPP on professional development and include: Socialization (through collective dissection experience and pathology), Humanistic Qualities (respect for the donor and their history, and introspection), and Content and Skills (technical and NTDIS, anatomical knowledge). The end of course FPP survey was completed by 29 students across three cohorts (65%) and their perspectives were generally favorable regarding the promotion of respect, empathy, and humanization of their donors. This study underscores the value of incorporating humanism, pathology, and reflection, facilitated through formal curriculum for pre-professional undergraduate students. It provides evidence of the positive impact on their personal and professional development, supporting the integration of NTDIS in curricula across various disciplines.

The Sun Also Rises: Tracing the evolution of humanistic values in anatomy pedagogy and research, including cadaveric acquisition practices

Anatomy has always been at the intersection of the socio-cultural and political landscape, where new ideas constantly replace older wisdom. From ancient Egyptians through the Greeks, and then the Romans, finally culminating into the European Renaissance-all the significant eras of human civilisation have left their insignia and distinct marks on the evolution of anatomical practices. Despite its utility as a tool for anatomy pedagogy and research that has proven its worth over millennia, cadaveric dissection has particularly been subject to political and social vicissitudes. A major debate about anatomical dissection lay with the ethical considerations, or its lack thereof, while acquiring corpses for demonstration in the dissection halls. From antiquity, anatomical dissection-often synonymous with medical studies-had typically been carried out on the dead bodies of executed criminals with certain laws, such as the Murder Act of 1752, facilitating such uses. Gradually, the uses of unclaimed bodies, resourced primarily from the impoverished sections of society, were also introduced. However, these body acquisition protocols often missed the crucial element of humanism and ethical considerations, while knowledge augmentation was taken as sufficient reasoning. Unfortunately, a gross disregard towards humanistic values promulgated heinous and illegal practices in acquiring corpses, including grave robbery and even murders like in the case of Burke and Hare murders of 1828. Follow-up legislation, such as the Anatomy Act of 1832, and comparable laws in other European nations were passed to curb the vile. What distils from such a historical discourse on humane values in anatomy dissection, or medical science in general, is that the growth and integration of humanism in anatomy have never been linear, but there were intermittent and, yet, significant disruptions in its timeline. For example, there were serious human rights violations in anatomical practices during the Third Reich in Germany that perpetrated the holocaust. The medical community has kept evolving and introducing new moral values and principles while using such egregious events as lessons, ultimately resulting in the Declaration of Helsinki in 1964. This article revisits the heterogeneous journey of integrating humanistic values in anatomy practice. Such humanistic traits that, like medical science, have also developed over centuries through the inputs of physicians, researchers, and philosophers-from Greece to modernity with an important stopgap at the Renaissance-are a fascinating lore that deserves to be re-envisioned through the lens of contemporary values and ethos. In parallel to human medicine, humanistic values continue to influence veterinary medicine, a welcome development, as our society condemns animal cruelty in any form. There are lessons to be learned from this historical journey of how humanism shaped many of the concepts that anatomists use now. Finally, and most importantly, it might prevent the medical community from repeating the same mistakes by cautioning against the traps that are there, and in a convoluted world where morality as such is eroding from our social fabric, will always be there. Such historical account acts as a righteous, ethical, and contextual compass to guide the existing and upcoming anatomists in discerning between light and dark, right and wrong, and roads-to be or not to be-taken.

"Where is the spleen? Where are the lungs?"-An investigation of the level of anatomical knowledge of the Hong Kong public

This article investigates the level of anatomical knowledge of the Hong Kong public and uses the data to help suggest public engagement activities and health campaigns to raise health literacy in the general population. In the annual public engagement event organized by the University of Hong Kong, 250 attendees took a survey assessing basic anatomical knowledge by putting organs/structures in their correct positions. Description analysis, correlation analysis, independent sample t-test, and one-way ANOVA analysis were conducted by SPSS 27.0. Overall, a mean score of 6.5 out of 20 was achieved. Differences between various demographic parameters were analyzed, and the results showed that better performance on the survey was associated with younger age, higher educational levels, and having healthcare experience. There was also a statistically significant difference in correctly positioning the thyroid between males and females. Interestingly, some misconceptions were thought to arise from the bespoke use of the Chinese language in the survey. The data reflected room for improvement in the level of anatomical knowledge among the public, notably in the older age groups. This was attributed partially to a lack of public outreach initiatives and established anatomy-focused programs, which has restricted public exposure to anatomical knowledge and hindered the development of anatomical sciences in Hong Kong. In conclusion, the knowledge of the public on the human body needs to be improved and possible solutions to improve public awareness of health were raised.

Perceptions and Challenges Faced by Undergraduate Medical Students in Studying Anatomy: A Case Study at Kampala International University - Western Campus, Uganda

Background

Proficiency in anatomy is of great importance for healthcare professionals and medical students alike, as it facilitates a comprehensive understanding of the structure and function of the human body. Despite the obvious significance, medical students have often felt challenged in studying anatomy.

Purpose

The studyassessed the perceptions and challenges faced by undergraduate medical students in studying anatomy at Kampala International University - Western Campus (KIU-WC) in Uganda.

Materials and Methods

Employing a quantitative cross-sectional descriptive design, the study involved the administration of a standardized questionnaire to a cohort of 525 first- and second-year medical students. The questionnaire encompassed sections on student perceptions and challenges faced in studying anatomy.

Results

The findings revealed that the majority of respondents 473/525 (90%) held positive perceptions of anatomy recognizing its importance in diagnosis, understanding the human body, medical terminology acquisition, and clinical preparation. While age (OR = 1.03, 95% CI: 0.54 - 1.97, p=0.93) and gender (OR = 0.51, 95% CI: 0.32 - 0.87, p=0.93) did not significantly impact student perceptions, positive perceptions were observed across different religious affiliations and nationalities, suggesting the universal recognition of anatomy's importance. The commonest challenges were a limited time for revision before their mid-semester and end-of-semester examination 383/525 (73.0%), information overload 374/525 (71.2%) and a lack of suitable equipment and poor internet connection for assessing online resources 352/525 (67.1%).

Conclusion

Focus on evidence-based anatomy in contemporary anatomy education: Arguments in favor of a pragmatic approach

The concept of evidence-based anatomy (EBA) emerged in 2014 and has become a significant element in contemporary anatomy education. The evolving fabric of the medical education curriculum has necessitated critical changes in practice. EBA enables these changes to be incorporated seamlessly and implemented congruently into anatomy education programs. However, in parallel, non-evidence-based (classical) knowledge that has been built up through centuries of anatomical practice continues to be the core element of anatomy education in some countries/regions. Its inherent limitations hinder integration with clinical practice, leading to a rise in misadventures in the clinical setting. This viewpoint commentary highlights the strengths of EBA vis-à-vis the related attributes of classical anatomy. Appropriate arguments show that EBA helps to reduce cognitive load and enables knowledge to be delivered through innovative education tools. EBA also helps to create an inclusive learning environment in a technology-driven era. Moreover, empowered by robust resources, it is driving the pertinent amalgamation of anatomy knowledge with clinical practice. This viewpoint article endorses the adoption of EBA in contemporary anatomy education on the basis of its potential for shaping future anatomical practice.

Johannes Nathanael Lieberkühn (1711-1756): luminary eighteenth century anatomist and his illuminating discovery of intestinal glands

Johannes Nathanael Lieberkühn was a prodigious anatomist whose meticulous experiments and precise detailing helped in comprehending the microscopic anatomy of digestive system during early part of eighteenth century. Notably, his inventions in the field of microscopy aptly complemented his quest for anatomical knowledge at microscopic level. He designed a reflector (Lieberkühn reflector) which enhanced the amount of focussed light leading to bright illumination of tissue specimen. He invented the solar microscope which provided excellent resolution of minute anatomical details. Lieberkühn discovered the digestive juice secreting tubular glands (glands of Lieberkühn) present at the base of intestinal villi producing epithelial invaginations (crypts of Lieberkühn). He also described the intricate juxtaposition of blood vessels in relation to a single intestinal villi. Moreover, through empirically designed experimental set up, Lieberkühn was able to demonstrate the flow of lymph from intestinal villi to collecting lymphatic vessels. Also, his grandiose collection of laboratory specimens involving vascular anatomy are a testimony of his untiring efforts in academia. His contributions were seminal in comprehending the anatomy of digestive system and paved the way for future revelations. His work unveiled the enormous scope of microanatomy in medical science and catalysed the advent of histological staining methods a century later.

"A whole new perspective on how the body fits together"-An evaluation of a cadaver laboratory experience for high school students

The Center for Anatomy and Physiology Education has hosted interactive human cadaver laboratory tours for local high schools (ages 14-18) and undergraduate university students since 2014 to expose students to healthcare careers. Students receive information on the history of body donation and healthcare careers and observe human anatomy on prosections and with isolated organs. The goal of this study was to evaluate students' perceptions of the anatomy laboratory tours and their impact on students' interests in healthcare careers. Students completed pre- and post-tour questionnaires. Responses were analyzed using thematic analysis and linguistic inquiry. Of the 261 students who completed pre-tour questionnaires, 204 (78%) completed the post-tour questionnaire. Before the tour, students anticipated learning about human anatomy and expected to only see but not touch a cadaver. Most students expressed excitement and/or nervousness. A few students viewed the laboratory tour as an opportunity to test if they could see themselves in a healthcare career. After the tour, most students indicated that the tour either met or exceeded their expectations. Students found the laboratory tour to be educational and interesting and were surprised by the opportunity to interact with the donor. Numerous students expressed an increased interest in healthcare careers after the tour. Overall, students perceived the tour as an engaging experience that improved their anatomical knowledge and reinforced/increased their interest in healthcare careers. Academic institutions can positively impact local students by implementing an anatomy tour, sharing access to their in-house human cadaver laboratory, and recruiting instructors to share their anatomy expertise.

The place of ethics in practice of anatomical sciences: have we left our dark past behind and looking towards a bright future?

INTRODUCTION

Anatomical sciences involve handling of human tissues and, therefore, application of principles of bioethics is central to anatomical practice. For a considerable period of time, anatomy was practiced without ethical norms as concept of ethics developed during second half of twentieth century. Hence, possible glimpse into contrast in ethical standards between anatomy in the past and present was deemed as an intriguing research theme.

METHODS

A literature search was undertaken from indexed databases (Medline and Pubmed, Scopus, Embase, CINAHL Plus, Web of Science and Google Scholar). Relevant data were extracted from 37 articles that were selected from an initial pool of 752 articles based on search criteria set for the study.

RESULTS

Prevalent anatomical practices in the past such as dissection of executed criminals, acts of vivisection, illegal procurement of human remains, use of human tissues obtained as part of war crimes and dissection of human fetuses as well as their archival were analyzed through prism of established ethical norms in present day. The observations from past were presented vis-à-vis ethical practices undertaken in present times such as use of donated bodies and/or body parts procured through legal means for dissection, adherence to ethical norms during dissection, archival of human tissues mandating stringent regulation and dignified disposal of human remains. Existing loop holes were identified and future prospects regarding ethical standards in anatomy were highlighted based on rational judgment of existing trends.

CONCLUSION

The article concludes with defense on future prospects of ethics in anatomy based on documented arguments.

Evolution of a discipline-The changing face of anatomy

This special issue is unlike any other special issue published in this journal's history. You will not find the types of original research in anatomy and evolutionary biology that you are accustomed to seeing adorning the pages of The Anatomical Record. Instead, the articles included cover the past and future of the discipline of anatomy broadly and of the American Association for Anatomy (AAA) more narrowly, and through two specific rhetorical frames: ethics; and diversity, equity, and inclusion. The articles in this issue are divided into two sections. The first section traces the history of anatomy and addresses many of the ethical dilemmas we face as a result of that history. The second section sets the stage for how the discipline and the AAA move forward to create a more diverse, equitable, and inclusive future for students, teachers, colleagues, and everyone else we touch through our work as anatomists. While this is only the beginning of our reconciliation with our past, the future certainly looks bright.
