Ghosh SK. Evolution of illustrations in anatomy: a study from the classical period in Europe to modern times. ANATOMICAL SCIENCES EDUCATION 2015; 8:175-188. [PMID: 25053471 DOI: 10.1002/ase.1479] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/23/2014] [Revised: 04/29/2014] [Accepted: 07/01/2014] [Indexed: 06/03/2023]
Abstract
Illustrations constitute an essential element of learning anatomy in modern times. However it required a significant evolutionary process spread over centuries, for illustrations to achieve the present status in the subject of anatomy. This review article attempts to outline the evolutionary process by highlighting on the works of esteemed anatomists in a chronological manner. Available literature suggests that illustrations were not used in anatomy during the classical period when the subject was dominated by the descriptive text of Galen. Guido da Vigevano was first to use illustrations in anatomy during the Late Middle Ages and this concept developed further during the Renaissance period when Andreas Vesalius pioneered in illustrations becoming an indispensable tool in conveying anatomical details. Toward later stages of the Renaissance period, Fabricius ab Aquapendente endeavored to restrict dramatization of anatomical illustrations which was a prevalent trend in early Renaissance. During the 18th century, anatomical artwork was characterized by the individual styles of prominent anatomists leading to suppression of anatomical details. In the 19th century, Henry Gray used illustrations in his anatomical masterpiece that focused on depicting anatomical structures and were free from any artistic style. From early part of the 20th century medical images and photographs started to complement traditional handmade anatomical illustrations. Computer technology and advanced software systems played a key role in the evolution of anatomical illustrations during the late 20th century resulting in new generation 3D image datasets that are being used in the 21st century in innovative formats for teaching and learning anatomy.

Rich P, Guy R. A "do-it-yourself" interactive bone structure module: development and evaluation of an online teaching resource. ANATOMICAL SCIENCES EDUCATION 2013; 6:107-113. [PMID: 23027675 DOI: 10.1002/ase.1312] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/04/2012] [Accepted: 08/10/2012] [Indexed: 05/28/2023]
Abstract
A stand-alone online teaching module was developed to cover an area of musculoskeletal anatomy (structure of bone) found to be difficult by students. The material presented in the module was not formally presented in any other way, thus providing additional time for other curriculum components, but it was assessed in the final examination. The module was developed using "in-house" software designed for academics with minimal computer experience. The efficacy and effectiveness of the module was gauged via student surveys, testing student knowledge before and after module introduction, and analysis of final examination results. At least 74% of the class used the module and student responses were positive regarding module usability (navigation, interaction) and utility (learning support). Learning effectiveness was demonstrated by large significant improvements in the post-presentation test scores for "users" compared with "non-users" and by the percentage of correct responses to relevant multiple choice questions in the final examination. Performance on relevant short answer questions in the final examination was, on average, comparable to that for other components. Though limited by study structure, it was concluded that the module produced learning outcomes equivalent to those generated by more traditional teaching methods. This "Do-It-Yourself" e-learning approach may be particularly useful for meeting specific course needs not catered for by commercial applications or where there are cost limitations for generation of online learning material. The specific approaches used in the study can assist in development of effective online resources in anatomy.

Abstract
While there is evidence that science and non-science background students display small differences in performance in basic and clinical sciences, early in a 4-year, graduate entry medical program, this lessens with time. With respect to anatomy knowledge, there are no comparable data as to the impact previous anatomy experience has on the student perception of the anatomy practical learning environment. A study survey was designed to evaluate student perception of the anatomy practical program and its impact on student learning, for the initial cohort of a new medical school. The survey comprised 19 statements requiring a response using a 5-point Likert scale, in addition to a free text opportunity to provide opinion of the perceived educational value of the anatomy practical program. The response rate for a total cohort of 82 students was 89%. The anatomy practical program was highly valued by the students in aiding their learning of anatomy, as indicated by the high mean scores for all statements (range: 4.04-4.7). There was a significant difference between the students who had and had not studied a science course prior to entering medicine, with respect to statements that addressed aspects of the course related to its structure, organization, variety of resources, linkage to problem-based learning cases, and fairness of assessment. Nonscience students were more positive compared to those who had studied science before (P levels ranging from 0.004 to 0.035). Students less experienced in anatomy were more challenged in prioritizing core curricular knowledge. Clin. Anat. 24:664-670, 2011. © 2011 Wiley-Liss, Inc.

Abstract
The aim of our study was to evaluate the use of the medical Internet by midwifery students with analysis of influencing factors and students' preferences. A prospective cross-sectional questionnaire study was carried out with 180 midwifery students. The response rate was 83.8%, 82% use the Internet, and 79.3% use the medical resources in their education. The mean accession to the Web is 5.3 +/- 8.4 times per month. The mean evaluation of information resources for books, journals, conferences and university courses was 6.6 +/- 3.2, 4.8 +/- 3.1, 2.7 +/- 3.0, and 6.8 +/- 3.8, respectively, as measured with the Visual Analogue Scale (p < 0.001). Age did not correlate with Internet use and its evaluation but correlated with a self-evaluation of Internet skills as a user (Rs = -0.20, p = 0.016). The evaluation of the Internet as a source of medical knowledge correlated with self-evaluation of medical search skills (Rs = 0.66, p < 0.001) and user skills (Rs = 0.61, p < 0.001). The medical Internet is used by the majority of midwifery students, but it is still a secondary source of information, after university training and medical books. The higher evaluation of Internet correlated with general computer skills and medical search skills, which suggests the need for education on Internet use by students.

Abstract
Unlike volume models, surface models, which are empty three-dimensional images, have small file size, so that they can be displayed, rotated, and modified in a real time. For the reason, the surface models of liver and neighboring structures can be effectively applied to virtual hepatic segmentectomy, virtual laparoscopic cholecystectomy, and so on. The purpose of this research is to present surface models of detailed structures inside and outside the liver, which promote medical simulation systems. Forty-seven chosen structures were liver structures such as portal triad, hepatic vein, and neighboring structures such as the stomach, duodenum, muscles, bones, and skin. The structures were outlined in the serially sectioned images from the Visible Korean Human to prepare segmented images. From the segmented images, serial outlines of each structure were stacked; on the popular commercial software, advanced surface reconstruction technique was applied to build surface model of the structure. A surface model of the liver was divided into eight models of hepatic segments according to distribution of the portal vein. The surface models will be distributed to encourage researchers to develop the various kinds of medical simulation of the abdomen.

Abstract
BACKGROUND The introduction of a problem-based learning (PBL) curriculum at the School of Medicine of the University of Melbourne has necessitated a reduction in the number of lectures and limited the use of dissection in teaching anatomy. In the new curriculum, students learn the anatomy of different body systems using PBL tutorials, practical classes, pre-dissected specimens, computer-aided learning multimedia and a few dissection classes. The aims of this study are: (1) to assess the views of first- and second-year medical students on the importance of dissection in learning about the anatomy, (2) to assess if students' views have been affected by demographic variables such as gender, academic background and being a local or an international student, and (3) to assess which educational tools helped them most in learning the anatomy and whether dissection sessions have helped them in better understanding anatomy. METHODS First- and second-year students enrolled in the medical course participated in this study. Students were asked to fill out a 5-point Likert scale questionnaire. Data was analysed using Mann-Whitney's U test, Wilcoxon's signed-ranks or the calculation of the Chi-square value. RESULTS The response rates were 89% for both first- and second-year students. Compared to second-year students, first-year students perceived dissection to be important for deep understanding of anatomy (P < 0.001), making learning interesting (P < 0.001) and introducing them to emergency procedures (P < 0.001). Further, they preferred dissection over any other approach (P < 0.001). First-year students ranked dissection (44%), textbooks (23%), computer-aided learning (CAL), multimedia (10%), self-directed learning (6%) and lectures (5%) as the most valuable resources for learning anatomy, whereas second-year students found textbooks (38%), dissection (18%), pre-dissected specimens (11%), self-directed learning (9%), lectures (7%) and CAL programs (7%) as most useful. Neither of the groups showed a significant preference for pre-dissected specimens, CAL multimedia or lectures over dissection. CONCLUSIONS Both first- and second-year students, regardless of their gender, academic background, or citizenship felt that the time devoted to dissection classes were not adequate. Students agreed that dissection deepened their understanding of anatomical structures, provided them with a three-dimensional perspective of structures and helped them recall what they learnt. Although their perception about the importance of dissection changed as they progressed in the course, good anatomy textbooks were perceived as an excellent resource for learning anatomy. Interestingly, innovations used in teaching anatomy, such as interactive multimedia resources, have not replaced students' perceptions about the importance of dissection.

Abstract
The zinc endopeptidase meprin (EC 3.4.24.18) is expressed in brush border membranes of intestine and kidney tubules, intestinal leukocytes, and certain cancer cells, suggesting a role in epithelial differentiation and cell migration. Here we show by RT-PCR and immunoblotting that meprin is also expressed in human skin. As visualized by immunohistochemistry, the two meprin subunits are localized in separate cell layers of the human epidermis. Meprin alpha is expressed in the stratum basale, whereas meprin beta is found in cells of the stratum granulosum just beneath the stratum corneum. In hyperproliferative epidermis such as in psoriasis vulgaris, meprin alpha showed a marked shift of expression from the basal to the uppermost layers of the epidermis. The expression patterns suggest distinct functions for the two subunits in skin. This assumption is supported by diverse effects of recombinant meprin alpha and beta on human adult low-calcium high-temperature keratinocytes. Here, beta induced a dramatic change in cell morphology and reduced the cell number, indicating a function in terminal differentiation, whereas meprin alpha did not affect cell viability, and may play a role in basal keratinocyte proliferation.

Abstract
We have investigated collaborative learning of anatomy over Internet2, using an application called remote stereo viewer (RSV). This application offers a unique method of teaching anatomy, using high-resolution stereoscopic images, in a client-server architecture. Rotated sequences of stereo image pairs were produced by volumetric rendering of the Visible female and by dissecting and photographing a cadaveric hand. A client-server application (RSV) was created to provide access to these image sets, using a highly interactive interface. The RSV system was used to provide a "virtual anatomy" session for students in the Stanford Medical School Gross Anatomy course. The RSV application allows both independent and collaborative modes of viewing. The most appealing aspects of the RSV application were the capacity for stereoscopic viewing and the potential to access the content remotely within a flexible temporal framework. The RSV technology, used over Internet2, thus serves as an effective complement to traditional methods of teaching gross anatomy.

Abstract
Virtual anatomy presents significant advantages over the reality of a cadaver as it can provide different views and perspectives, portability, longevity, standardization, diversity and most importantly the opportunity to learn the anatomy of the living human body instead of the corpse. Virtual anatomy is the life-like appearance of visible anatomy, a good example of which is the evolution of the Visible Human. Racial and statistical diversity is already developing as the population of photographic "Visible Humans" is now at least 10. Virtual anatomy should include additional diversity and therefore, consideration should be given to the preparation of more visible anatomy that will better support the virtual integration of all areas of physiology, kinematics, pathology and pathophysiology, development and evolution. Integration of anatomists with mathematicians, computer scientists, information scientists, physiologists, pathologists and clinicians (and LIST other basic scientist) is needed in order to facilitate this development. As this unfolds it is proposed, or challenged, that anatomists should maintain their position of responsibility for building anatomy as the foundation for all medical and healthcare education. In order to maintain that position they must understand and participate in this development and enjoy the rewards of teaching more visually empowering, functional, and clinical anatomy. The trip is a long one and is only about to begin but the train is leaving. Are you on board?

Abstract
PURPOSE 'Craniofacial imaging informatics' refers to image and related scientific data from the dentomaxillofacial complex, and application of 'informatics techniques' (derived from disciplines such as applied mathematics, computer science and statistics) to understand and organize the information associated with the data. METHOD Major trends in information technology determine the progress made in craniofacial imaging and informatics. These trends include industry consolidation, disruptive technologies, Moore's law, electronic atlases and on-line databases. Each of these trends is explained and documented, relative to their influence on craniofacial imaging. RESULTS Craniofacial imaging is influenced by major trends that affect all medical imaging and related informatics applications. The introduction of cone beam craniofacial computed tomography scanners is an example of a disruptive technology entering the field. An important opportunity lies in the integration of biologic knowledge repositories with craniofacial images. CONCLUSION The progress of craniofacial imaging will continue subject to limitations imposed by the underlying technologies, especially imaging informatics. Disruptive technologies will play a major role in the evolution of this field.
