RESUMO
BACKGROUND: Anatomical terms in medical literature have been used with varying meanings, leading to confusion in clinical practice. This study aims to investigate the ambiguity of anatomical terms in clinical dentistry. METHODS: Dentists who have undergone specialised training with at least one year of clinical experience were recruited to participate in the study. They were requested to localize specific terms on a skull and provide explanations based on their experience or opinion. All data were recorded, and then descriptive statistics were used for analysis. RESULTS: Seventy-eight participating dentists gave their consent and were eligible to study. For each anatomical term presented to dentists at least two meanings were provided, with some terms having up to eight interpretations. While most meanings were consistent with medical or dental literature, some responses revealed new interpretations not documented in textbooks. CONCLUSIONS: Dentists expressed anatomical terms with diverse meanings, possibly influenced by their various subspecialties. It is crucial to acknowledge this variability to prevent confusion. Emphasizing the consistent use of anatomical terms among dental professionals in the future is essential.

INTRODUCTION: In response to the COVID-19 crisis, this study aimed to introduce a new virtual teaching model for anatomy education that combines Peer-Assisted Learning (PAL) and flipped classrooms, aligning with constructivist principles. METHOD: The Flipped Peer Assisted (FPA) method was implemented in a virtual neuroanatomy course for second-year medical students at Birjand University of Medical Sciences via a descriptive study. The method involved small groups of PAL, with peer learning serving as educational assistants and the teacher acting as a facilitator. Educational content was uploaded to the university's learning management system (LMS). The opinion of medical students regarding the teaching method were evaluated using a 15-item questionnaire on a five-point Likert scale. RESULTS: A total of 210 students participated in the instruction using the FPA method. The analysis of students' scores revealed an average score of 26.75 ± 3.67 on the 30-point test. According to student feedback, this teaching method effectively motivated students to study, enhanced teamwork and communication skills, transformed their perspective on the anatomy course, provided opportunities for formative assessment and feedback, and demonstrated the teacher's dedication to education. CONCLUSION: The FPA model demonstrates its effectiveness in transforming traditional classroom teaching and fostering teaching and learning in virtual environments, particularly during pandemics like COVID-19. This model holds promise for enhancing anatomy education in challenging circumstances.

BACKGROUND: The anatomy dissection course is a major part of the first two years of the traditional medical curriculum in Germany. The vast amount of content to be learned and the repeated examination is unanimously perceived by students and teachers as a major stress factor that contributes to the increase of psychosocial stress during the first two years of the course of study. Published interventions for specific stress reduction are scarce. METHODS: In a randomized, controlled design two intervention groups were compared with a control group (CG) over the whole dissection course (nine measuring points before, during and after first and second semester). The 'Stress Management intervention (IVSM)' targeted at the setting of personal standards, the 'Friendly Feedback intervention (IVFF)' at the context of frequent testing. Quantitative surveys were distributed at nine measuring points. The questionnaire comprised validated instruments and self-developed items regarding stress, positive and negative affect, anxiety, intrinsic and extrinsic motivation, self-efficacy, and perceived performance. RESULTS: Out of 195 students inscribed in the dissection course, 166 (85%) agreed to participate in the study. The experience of stress during the dissection course was significantly higher in the CG than in the IVFF. Anxiety and negative affect were lower in students of the IVFF while positive affect, intrinsic motivation, and self-efficacy were higher than in the CG. For anxiety and negative affect in the IVSM this was especially seen at the end of the second semester. The self-perceived increase in both knowledge and preparedness for the first big oral and written examination did not differ between the study groups. About three quarters of the participants would choose the intervention 'Friendly Feedback' if given the choice. CONCLUSIONS: Replacing formal tests with friendly feedback has proven to be an effective measure to reduce stress and negative affect and foster positive affect, self-efficacy, and intrinsic motivation, while it did not impair self-perceived academic performance.

INTRODUCTION: Anatomy teaching has traditionally been based on dissection. However, reduced hours in total and laboratory hours in gross anatomy along with a dearth of cadavers have ensued the search for a less time-consuming tool. MATERIALS AND METHODS: The study was conducted in the Department of Anatomy in Sheikh Bhikhari Medical College, Hazaribag. A total of 282 medical students were taught gross anatomy, using three different learning modalities: dissection (n = 95), plastic models (n = 94), and three-dimensional (3D) anatomy software (n = 93). The knowledge of the students was examined by 100 multiple-choice question (MCQ) and tag questions followed by an evaluation questionnaire. RESULTS: When performance is considered, the dissection and 3D group performed better than the plastic models group in total, MCQs, and tag questions. In the evaluation questionnaire, dissection performed better than the other two modalities. Moreover, dissection and 3D software emerged as superior to the plastic models group. STATISTICAL ANALYSIS: All data were analyzed using the one-way ANOVA and t-test. Group-based analysis by ANOVA and gender-based analysis were done by Student's t-test. A comparison of students' perceptions was done by Kruskal-Wallis H-test. CONCLUSION: Dissection remains a favorite with students and accomplishes a significantly higher attainment of knowledge. Plastic models are less effective but are a valuable tool in preparation for cadaveric laboratories.
Résumé Introduction:L'enseignement de l'anatomie est traditionnellement basé sur la dissection. Cependant, la réduction des heures totales et des heures de laboratoire en anatomie globale ainsi que la pénurie de cadavres ont entraîné la recherche d'un outil moins chronophage.Méthodologie:L'étude a été menée dans le département d'anatomie du Sheikh Bhikhari Medical College, Hazaribag. Au total, 282 étudiants en médecine ont appris l'anatomie globale, en utilisant trois modalités d'apprentissage différentes : dissection (n = 95), modèles plastiques (n = 94) et logiciel d'anatomie 3D (n = 93). Les connaissances des étudiants ont été examinées par 100 questions QCM et tags suivies d'un questionnaire d'évaluation.Résultats:Lorsque les performances sont prises en compte, le groupe dissection et 3D a obtenu de meilleurs résultats que le groupe modèles plastiques au total, questions à choix multiples et questions d'étiquettes. Dans le questionnaire d'évaluation, la dissection a donné de meilleurs résultats que les deux autres modalités. De plus, les logiciels de dissection et de 3D se sont révélés supérieurs au groupe des modèles plastiques.Analyse Statistique:Toutes les données ont été analysées à l'aide du test ANOVA et T unidirectionnel. L'analyse basée sur le groupe par Anova et l'analyse comparative entre les sexes ont été réalisées à l'aide du test t des étudiants. Une comparaison des perceptions des étudiants a été réalisée par le test Krushal Wallis H.Conclusion:La dissection reste l'une des préférées des étudiants et permet d'atteindre un niveau de connaissances nettement plus élevé. Les modèles en plastique sont moins efficaces mais constituent un outil précieux pour la préparation des laboratoires cadavériques.

PURPOSE: 3D visualization is an important part of learning anatomy with cadavers generally used to effectuate this. However, high cost, ethical considerations, and limited accessibility can often limit the suitability of cadavers as teaching tools. Anatomical 3D printed models offer an alternative tool for teaching gross anatomy due to their low cost and accessibility. This study aims to investigate if combing gamification with 3D printed models can enhance the learning experience and be effective for teaching anatomy. METHODS: 3D printed models of the bones of the foot and ankle were generated, and 267 first-year medical students from 2 consecutive cohorts worked in groups to put it together as a puzzle. Participants completed a questionnaire regarding perceptions of 3D models and their knowledge of foot anatomy, before and after the session and were asked to provide comments. RESULTS: Analysis of the responses showed a significant increase in the confidence of the learners in their anatomy knowledge and an increased appreciation of the role that 3D models have in enhancing the learning experience. After the session, there were many comments saying how enjoyable and engaging 3D models were. CONCLUSION: Through the puzzle element of the session, the students were challenged mentally to work out the anatomical features of the foot and ankle. The combined elements of the puzzle and the features of the 3D model assembly made the activity fun and conducive to active learning. The possibility of having fun was not something the students had considered before the session.

English anatomical terminology has evolved over the long history of anatomical practice, with major influences from ancient Greek, classical Latin, Arabic, and post-classical Latin. Beginning in the nineteenth century, there have been various attempts to standardise and rationalise anatomical language, beginning in 1887, and culminating in the publication in 2019 of the second edition of the Terminologia Anatomica. This paper presents a brief historical overview of the development of anatomical terminology and usage in English, followed by a summary of the results of an anonymised survey of current practices that was sent out by email to anatomy educators at 45 medical schools in the United Kingdom. This is followed by personal reflections by six senior academics and/or clinicians, reviewing their extensive experience of teaching, researching, and communicating the language of anatomy within United Kingdom medical and clinical institutions.

INTRODUCTION: There is little research on how medical school matriculants' experiences prior to medical school effects their choice of specialty or performance in medical school. This research attempts to fill that gap in research in regards to surgical and radiological fields. METHODS: An anonymous survey was sent to fourth year medical students asking them their background in anatomy studies prior to medical school and their anatomy grades in medical school and interest in surgical and radiological fields. Students were also asked whether they identified with under-represented demographic groups in those specialties. RESULTS: Prior anatomy experience did not significantly affect performance in anatomy courses or Step 1 and Step 2 scores. However, students who applied to surgical specialties had higher performance in anatomical courses and higher Step 1 scores compared to those who did not apply to surgical specialties. There was interestingly no difference in under-represented and not under-represented student application to these fields. DISCUSSION: For shareholders interested in increasing medical student performance, or interest in specific specialties, more information needs to be gathered.

Undergraduate medical students who participate in community outreach programs gain a multitude of benefits that impact not only their professional development but also the well-being of the communities they serve. At the Virginia Tech Carilion School of Medicine (VTCSOM), students have the opportunity to volunteer in the "Bodies and Bites" program at the West End Center for Youth, an after-school educational center that serves K-12 children in Roanoke, Virginia. The purpose of Bodies and Bites is to teach elementary school children in 2nd to 5th grade how their bodies work and how to keep them healthy through good nutrition and exercise. All sessions are led by VTCSOM medical students and graduate students from our partnering academic institution, the Fralin Biomedical Research Institute (FBRI). Each week, the children and Health Professions students explore a different topic related to human anatomy and physiology using anatomical models, small group discussions, and hands-on activities. At the end of each session, the participants create a healthy snack related to the day's topic. The overall goal of the present study was to assess the perception of the Bodies and Bites program from the view of our student volunteers, and the 4th and 5th graders who attend the West End Center. Now in its 6th year, Bodies and Bites continues to be popular as a voluntary program among our Health Professions students, and is well received by the West End Center and the elementary school children they serve. Our students and community mutually benefit from this program, with the former having an opportunity to briefly disengage from the rigors of their studies while gaining valuable skills in science communication and inspiring children to pursue fields in Science, Technology, Engineering, Math, and Medicine (STEMM), and the latter having fun while learning about their bodies and discovering ways to improve their health.

In recent years, human anatomy education has faced challenges with traditional donor dissection, leading to the emergence of virtual dissection as an alternative. This study aims to investigate the academic performance and satisfaction of medical students by comparing the virtual and donor dissections. An open-labeled crossover randomized controlled trial was conducted with 154 first-year medical students in Human Anatomy and Neuroanatomy laboratories, which were divided into three classes. Students were randomly assigned to either the virtual (virtual dissection followed by donor dissection) or donor (donor dissection followed by virtual dissection) groups in each class. A curriculum, incorporating head-mounted displays (HMDs), a life-sized touchscreen, and tablets, was developed. Data was evaluated through quizzes and surveys. In the Human Anatomy laboratory, each class of the donor group conducted heart extraction, dissection and observation. In observation class, the virtual group had a significantly higher mean quiz score than the donor group (p < 0.05). Compared to the donor, satisfaction was significantly higher for the HMD (understanding of concept and immersion), life-size touchscreen (esthetics, understanding of the concept, and spatial ability), and tablet (esthetics, understanding of the concept, spatial ability, and continuous use intention). In the Neuroanatomy laboratory, the virtual group showed significantly higher mean quiz scores than the donor group (p < 0.05), and tablet showed a significantly higher satisfaction than donor in terms of esthetics, understanding of the concept, and spatial ability. These results suggest that virtual dissection has the potential to supplement or replace donor dissection in anatomy education. This study is innovative in that it successfully delivered scenario-based virtual content and validated the efficacy in academic performance and satisfaction when using virtual devices compared to donor.Trial registration: This research has been registered in the Clinical Research Information Service (CRIS, https://cris.nih.go.kr/cris/search/detailSearch.do?search_lang=E&focus=reset_12&search_page=L&pageSize=10&page=undefined&seq=26002&status=5&seq_group=26002 ) with registration number "KCT0009075" and registration date "27/12/2023".

OBJECTIVE: This study aimed to assess the perceived need among surgical residents to revisit their anatomical knowledge and evaluate their attitude towards integrating clinical anatomists into surgical residency program curriculum. BACKGROUND: While medical students learn human anatomy during undergraduate years, the practical application of clinically oriented anatomy becomes vital in surgical specialties. However, this aspect has not been adequately addressed in Indian surgical residency programs. METHODS: An 11-item questionnaire, including closed-ended and Likert-scale questions, was administered to 153 surgical residents. Consent was obtained, and responses were collected via Google Forms. RESULTS: Half of the respondents (50%) felt confident in their self-directed anatomy learning, but 87% believed integrating clinical anatomists would enhance their surgical expertise. Additionally, 88% saw value in revisiting cadaveric dissection. Third-year residents showed a significantly higher inclination towards cadaveric dissection. Deficiencies in the curriculum and time constraints were identified as major barriers. CONCLUSION: The study highlights a perceived need among surgical residents to augment their anatomical knowledge, advocating for the integration of clinical anatomists and cadaveric dissection into training. A collaborative approach, emphasizing both horizontal and vertical integration of anatomy, is recommended to enhance surgical education and practice. (Tab. 4, Fig. 1, Ref. 25).

The changing of education activities (offline into online) to reduce coronavirus transmission during COVID-19 pandemi has influence on the learning strategies, which ultimately might impact the achievement of learning objectives. Therefore, we conducted a cross-sectional study using a valid (p < 0.01; two-tailed Pearson correlation) and reliable (r = 0.878 and r = 0.849; Cronbach Alpha) online questionnaire to evaluate the perspectives of human anatomy lecturers and undergraduate medical students in Indonesia in implementing the online anatomy learning. We also explored their expectations and preferred learning methods after COVID-19 pandemic. Using purposive sampling, 467 respondents, which consisted of 66 lecturers from 41 universities in six islands (Java, Sumatera, Kalimantan, Sulawesi, Nusa Tenggara and Papua) and 401 students from 19 universities in four islands (Java, Sumatera, Kalimantan, Papua) were recruited. A Chi-square test was used to analyze the differences in categorical variables. The lecturers (74.2%) and students (63.1%) agreed that online learning effectively delivered the course material (p = 0.095). They (69.7% lecturers and 57.9% students) also agreed that learning time allocation was sufficient (p = 0.079); moreover, lecturers (53%) and students (56.1%) had good interaction (p = 0.689). Nevertheless, 56.1% lecturers and 63.3% students had problem during online practical sessions. They had different perspectives about issues during online classes (69.7% vs 36.4%; p < 0.01), motivation improvement (72.7% vs 37.4%; p < 0.01), and time management (87.9% vs 58.4%; p < 0.01). According to the location of the university, especially in the student's side, students in Java had higher proportion in the two aspects, i.e. learning material (p < 0.01) and lecturer-student interaction (p < 0.01), and had lower proportion in the problems during online class (p = 0.003) and practical sessions (p = 0.008). Majority of the respondents (62,2% lecturers in Java, 71.4% lecturers outside Java, 79.6% Students in Java, and 76.6% students outside Java) preferred the use of blended learning after the pandemic (new normal era) and expected to continue the cadaveric practical sessions (82.2% lecturers in Java, 81.0% lecturers outside Java, 91.1% students in Java, and 78.3% students outside Java). In conclusion, the study showed that the satisfaction toward online anatomy learning related to the subject's role (lecturer or student) and the university region in some aspects.

Anatomical drawing traditionally involves illustration of labeled diagrams on two-dimensional surfaces to represent topographical features. Despite the visual nature of anatomy, many learners perceive that they lack drawing skills and do not engage in art-based learning. Recent advances in the capabilities of technology-enhanced learning have enabled the rapid and inexpensive production of three-dimensional anatomical models. This work describes a "drawing on model" activity in which learners observe and draw specific structures onto three-dimensional models. Sport and exercise sciences (SES, n = 79) and medical (MED, n = 156) students at a United Kingdom medical school completed this activity using heart and femur models, respectively. Learner demographics, their perceptions of anatomy learning approaches, the value of the activity, and their confidence in understanding anatomical features, were obtained via validated questionnaire. Responses to 7-point Likert-type and free-text items were analyzed by descriptive statistics and semi-quantitative content analysis. Learners valued art-based study (SES mean = 5.94 SD ±0.98; MED = 5.92 ± 1.05) and the "drawing on model" activity (SES = 6.33 ± 0.93; MED = 6.21 ± 0.94) and reported enhanced confidence in understanding of cardiac anatomy (5.61 ± 1.11), coronary arteries (6.03 ± 0.83), femur osteology (6.07 ± 1.07), and hip joint muscle actions (5.80 ± 1.20). Perceptions of learners were independent of both their sex and their art-based study preferences (p < 0.05). Themes constructed from free-text responses identified "interactivity," "topography," "transformative," and "visualization," as key elements of the approach, in addition to revealing some limitations. This work will have implications for anatomy educators seeking to engage learners in an inclusive, interactive, and effective learning activity for supporting three-dimensional anatomical understanding.

OBJECTIVE: To evaluate the outcome of Augmented reality technology in the recognizing of oral and maxillofacial anatomy. METHODS: This study was conducted on the undergraduate students in Peking University School of Stomatology who were learning oral and maxillofacial anatomy. The image data were selected according to the experiment content, and the important blood vessels and bone tissue structures, such as upper and lower jaws, neck arteries and veins were reconstructed in 3D(3-dimensional) by digital software to generate experiment models, and the reconstructed models were encrypted and stored in the cloud. The QR (quick response) code corresponding to the 3D model was scanned by a networked mobile device to obtain augmented reality images to assist experimenters in teaching and subjects in recognizing. Augmented reality technology was applied in both the theoretical explanation and cadaveric dissection respectively. Subjects' feedback was collected in the form of a post-class questionnaire to evaluate the effectiveness of augmented reality technology-assisted recognizing. RESULTS: In the study, 83 undergraduate students were included as subjects in this study. Augmented reality technology could be successfully applied in the recognizing of oral and maxillofacial anatomy. All the subjects could scan the QR code through a connected mobile device to get the 3D anatomy model from the cloud, and zoom in/out/rotate the model on the mobile. Augmented reality technology could provide personalized 3D model, based on learners' needs and abilities. The results of likert scale showed that augmented reality technology was highly recognized by the students (9.19 points), and got high scores in terms of forming a three-dimensional sense and stimulating the enthusiasm for learning (9.01 and 8.85 points respectively). CONCLUSION: Augmented reality technology can realize the three-dimensional visualization of important structures of oral and maxillofacial anatomy and stimulate students' enthusiasm for learning. Besides, it can assist students in building three-dimensional space imagination of the anatomy of oral and maxillofacial area. The application of augmented reality technology achieves favorable effect in the recognizing of oral and maxillofacial anatomy.

INTRODUCTION: Informed consent is critical for maintaining the ethical standards associated with the utilization of human donor bodies by tertiary education institutions. Body donation programs undertake the responsibility for procuring human donor bodies for didactic and research purposes. However, its processes require scrutiny regarding best practice guidelines and the South African National Health Act (SA-NHA) (2013). Moreover, acknowledging and addressing the current perceptions of human body donation are indispensable in bridging the gap between academia and society. This study aimed to compare informed consent documentation and procedures across South African tertiary education institutions and their affiliated human body donation programs (HBDP) in accordance with international guidelines. The findings were used to create a human body donation form template aligned to current international best practices for consideration by the South African HBDP. METHODOLOGY: A review of information and consent forms collected from South Africa's eight HBDP was conducted. The analyses consisted of a broad evaluation of information provided, ranging from the terms-of-use for human donor bodies to the commitments made by HBDP to body-donors. The results were considered in conjunction with the International Federation of Associations of Anatomists and other recent publications on informed consent in HBDP. RESULTS: Only two of the eight HBDP provided information and consent forms in more than one language. Most allowed donors to select how their bodies will be utilized - education, training and/or research. Some (6/8) made provisions for the next-of-kin to receive the cremains. Only one tertiary educational institution mentioned the occurrence of a memorial service in its documentation. An HBDF template was created aligned to current international best practices for presentation and possible adaption by SA HBDP. DISCUSSION & CONCLUSIONS: Human body donation forms (HBDF) requires thorough examination for the promotion and sustainability of HBDP. Effective communication by employing standardized non-technical terminology conveyed in language that is understandable and native to potential donors facilitates the deliverance of informed consent. Inconsistencies regarding the use and management of bodies catalyze the weakening perception of human body donation. Thus, this process of securing informed consent for body donation should be conducted in conjunction with public awareness campaigns and underpinned by the necessary policy and legislative reform.

Body embalming, a practice with deep historical roots across various cultures, forms the backbone of contemporary human body donation educational programmes. In this study, we explored current embalming practices within six South African human anatomical dissection programmes, focusing on the use and volumes of key chemicals-formalin, phenol, and alcohol-and their associated health risks and potential toxicity. We measured and compared aspects of embalming practices such as the duration of body preservation and the annual intake of bodies. Variations in embalming practices and chemical ratios across different South African universities were found. However, the consistent use of formalin, phenol and alcohol were observed across all six programmes. Formaldehyde concentrations used in South African dissection programmes were within the generally acceptable international range. Regarding arterial embalming, South African dissection programmes showed widespread adherence to international embalming practices, with one programme using a substantially lower concentration of formalin. The dual nature of formaldehyde as both an effective preservative and a recognised carcinogen was underscored in relation to human health regarding chemical toxicity. Phenol, like formaldehyde, was consistently used as it is important for the inhibition of bacterial and fungal growth. Alcohol was also consistently used, but there was much greater variation in its volume across South African institutions. Our data showed a slight positive relationship between storage duration and the volumes of formalin and phenol in human embalming fluid. South African regulators enforce stricter exposure limits than those set by the World Health Organisation and various European agencies. While South African institutions operate within internationally acceptable ranges of chemical use that both maximise preservation and minimise toxicity, we acknowledge that these data are preliminary. Further investigation is encouraged to ensure embalming practices effectively protect all those involved and support the educational goals of human anatomical dissection programmes in South Africa.

PURPOSE: The current study proposes the comparison of the visualization and identification of anatomical details between natural human temporal bone, its respective copy from three-dimensional printing, and the virtual model obtained from CBCT. METHODS: The sample consisted of undergraduate students in Dentistry (Group UE, n = 22), Postgraduate students in Radiology and Imaging (Group P-RI, n = 20), and Postgraduate students in Forensic Odontology (Group P-FO, n = 24). All participants attended a theoretical class on specialized anatomy of the temporal bone and subsequently performed the markings of 10 determined structures. RESULTS: The number of correct identifications was similar in natural bone and printed three-dimensional models in all groups (p > 0.05). The virtual model showed a significantly lower number of correct structures (p < 0.05) in the 3 groups. In general, there were significantly higher percentages of accurate answers among postgraduate students compared to undergraduate students. Most graduate students believed that the printed three-dimensional model could be used to teach anatomy in place of natural bone, while undergraduate students disagreed or were unsure (p < 0.05). Regarding the virtual tomographic image, in all groups, students disagreed or were not sure that its use would be beneficial in replacing natural bone. CONCLUSION: Three-dimensional and virtual models can be used as auxiliary tools in teaching anatomy, complementing practical learning with natural bones.
