RESUMEN

Large Language Models (LLMs) have the potential to improve education by personalizing learning. However, ChatGPT-generated content has been criticized for sometimes producing false, biased, and/or hallucinatory information. To evaluate AI's ability to return clear and accurate anatomy information, this study generated a custom interactive and intelligent chatbot (Anatbuddy) through an Open AI Application Programming Interface (API) that enables seamless AI-driven interactions within a secured cloud infrastructure. Anatbuddy was programmed through a Retrieval Augmented Generation (RAG) method to provide context-aware responses to user queries based on a predetermined knowledge base. To compare their outputs, various queries (i.e., prompts) on thoracic anatomy (n = 18) were fed into Anatbuddy and ChatGPT 3.5. A panel comprising three experienced anatomists evaluated both tools' responses for factual accuracy, relevance, completeness, coherence, and fluency on a 5-point Likert scale. These ratings were reviewed by a third party blinded to the study, who revised and finalized scores as needed. Anatbuddy's factual accuracy (mean ± SD = 4.78/5.00 ± 0.43; median = 5.00) was rated significantly higher (U = 84, p = 0.01) than ChatGPT's accuracy (4.11 ± 0.83; median = 4.00). No statistically significant differences were detected between the chatbots for the other variables. Given ChatGPT's current content knowledge limitations, we strongly recommend the anatomy profession develop a custom AI chatbot for anatomy education utilizing a carefully curated knowledge base to ensure accuracy. Further research is needed to determine students' acceptance of custom chatbots for anatomy education and their influence on learning experiences and outcomes.

RESUMEN

Despite attempts to diversify healthcare workplaces and education, racial and ethnic minorities (REM) remain underrepresented in these fields. This study investigated changes in high school students' health science interest following a single exposure, hands-on anatomy laboratory visit. One hundred and eighty-eight high school students participated in a single day, one-hour visit to a human anatomy laboratory on a university campus. Participants engaged in hands-on activities centered around both human and animal specimens led by university mentors. Using a modified Science Technology Engineering and Mathematics-Career Interest Survey (STEM-CIS) questionnaire, health science STEM interest was calculated before and after the visits and compared using a paired t-test (α = 0.05). A 2 × 2 ANOVA (α = 0.05) was run on pre-to-post-visit interest score differences with factors of Race (White/REM) and Gender (Male/Female) to determine if race/ethnicity and/or gender moderated the gains observed. Overall, health science STEM interest increased significantly from pre- to post-visit (p < 0.001), and these gains were greater in REM students (p < 0.05) but did not differ as a function of gender. These findings indicate that a single visit to an anatomy laboratory with hands-on activities can be used as a tool to engage high school aged students in STEM and may be particularly beneficial for racial/ethnic minority students, potentially influencing health science STEM interest.

RESUMEN

BACKGROUND: Body donation is a predominant mode of body sourcing in many countries including South Africa; however, it continues to be limited among the different ethnic groups in the Black African population of South Africa which have been observed to be largely unwilling to provide consent to donate their bodies. Religious and cultural beliefs have been suggested to influence willingness to donate one's body to science, with most religions regarded as accepting of body donation globally. In contrast, cultural beliefs and practices in the African continent impede body donation. Therefore, it is crucial to understand the factors that influence willingness to participate in body donation among the various ethnic groups of the Black African population of South Africa, particularly the Pedi ethnic group. PURPOSE: This study sought to investigate factors that determine the disposition to participate in body donation and the influence of religious and cultural beliefs on willingness to consent to donate one's body among a predominantly Pedi community of the Black African population of South Africa in the Limpopo province. METHODS: In this cross-sectional study, 300 four-page questionnaires were distributed to conveniently sampled individuals from the GaMaphale (Pipa) village of the Limpopo province of South Africa. Descriptive statistics (frequency tables and Pearson's chi-square test for independence) followed by a stepwise backward regression were conducted to obtain key factors determining willingness to donate one's body, the influence of religious and cultural beliefs, and also the likelihood of willingness to participate in body donation in this community. A p-value of < 0.05 was considered statistically significant. RESULTS: A total of 190 (63 %) responses were obtained. The level of awareness about body donation was 30 % (n= 57/190), and 41 % (n= 78/190) of respondents were willing to donate their bodies. Age (p = 0.001), educational level (p = 0.037), belief in a higher entity (p = 0.007), ancestral (p < 0.001), and religious (p < 0.001) beliefs allowing for body donation were statistically associated with willingness to donate one's body. The elderly respondents were less likely to agree to donate their bodies compared to younger adults. Respondents who understood that religion allowed them to self-donate were 50 times more likely to agree to donate their bodies than those who did not. DISCUSSION AND CONCLUSION: Findings reflect that a high percentage of respondents were unaware of body donation while a considerable number of respondents were willing to donate their bodies to science based on their religious and cultural beliefs allowing them to do so. Potential body donors from this community will likely be younger and belong to religions that allow body donation. The need to increase awareness about body donation programs through awareness campaigns, especially among religious organizations that may allow for body donation, is warranted in this community. This work was supported by the National Research Foundation (TTK220214660416).

RESUMEN

BACKGROUND: The teaching of anatomy from early days of medical education relied on the use of cadaver; hence, the present study assessed the support for whole-body donation among academic staff. METHODS: This is a cross-sectional study conducted from January to March 2024 in Southwestern Ugandan medical educational schools among 160 academic staff. Ethical approval was obtained and structured questionnaires were distributed to study participants in the selected Medical Educational Schools. RESULTS: Among the 160 sampled academic staff, only 16 % and 18 % supported the donation of their whole-body and the bodies of their relatives/friends for anatomical education respectively. The reason put forward for respondents support for whole-body donation were contribution to medical science (88.5 %) and learnt from someone's body (53.8 %). The fear of misuse of their body (42.5 %), cultural (53.7 %) and religious (44.8 %) belief were the reasons for non-support for whole-body donation among the study participants. CONCLUSION: This study concluded that support for whole-body donation among academic staff was low; reasons for non-support were fear of misuse of body, religious and cultural beliefs; hence, we recommend the need for massive desensitization of the public aimed at building confidence on whole-body donation in the community.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Plastination, a permanent preservation method for human tissues and organs, is increasingly being used in anatomy education. However, there is a paucity of systematic reviews and meta-analyses summarizing the educational efficacy of plastinated specimens. This meta-analysis compared the assessment scores of students exposed to plastinated specimens against those exposed to other common instructional methods. A systematic search was conducted through four databases, from 2000 to July 2022. Titles and abstracts of the retrieved records were screened according to predetermined eligibility criteria. Of the 159 records screened, 18 were subjected to full-text review. Among the 18 studies, five articles reported post-intervention test scores for intervention (plastinated) and control (other modalities) groups. Studies were subjected to GRADE quality assessment, and four studies with moderate to high ratings were included for meta-analysis. Students' perceptions (n = 15 studies) were qualitatively analyzed using an inductive narrative analysis. No significant effect was detected between the intervention (n = 417) and control groups (n = 422) (standardized mean difference = 0.08; 95% CI [-0.36, 0.52]; p = 0.73). Four themes emerged from students' perceptions: ease of use, motivation to study, spatial understanding, and learning preference. Overall, student performance outcomes comparing the use of plastinated specimens versus other instructional modalities are very limited. This meta-analysis suggests that knowledge gained from plastinated specimens is comparable to learning achieved through other modalities; though this outcome should be interpreted with caution as there is currently insufficient evidence for definitive conclusions.

RESUMEN

Anatomical education is pivotal for medical students, and innovative technologies like augmented reality (AR) are transforming the field. This study aimed to enhance the interactive features of the AEducAR prototype, an AR tool developed by the University of Bologna, and explore its impact on human anatomy learning process in 130 second-year medical students at the International School of Medicine and Surgery of the University of Bologna. An interdisciplinary team of anatomists, maxillofacial surgeons, biomedical engineers, and educational scientists collaborated to ensure a comprehensive understanding of the study's objectives. Students used the updated version of AEducAR, named AEducAR 2.0, to study three anatomical topics, specifically the orbit zone, facial bones, and mimic muscles. AEducAR 2.0 offered two learning activities: one explorative and one interactive. Following each activity, students took a test to assess learning outcomes. Students also completed an anonymous questionnaire to provide background information and offer their perceptions of the activity. Additionally, 10 students participated in interviews for further insights. The results demonstrated that AEducAR 2.0 effectively facilitated learning and students' engagement. Students totalized high scores in both quizzes and declared to have appreciated the interactive features that were implemented. Moreover, interviews shed light on the interesting topic of blended learning. In particular, the present study suggests that incorporating AR into medical education alongside traditional methods might prove advantageous for students' academic and future professional endeavors. In this light, this study contributes to the growing research emphasizing the potential role of AR in shaping the future of medical education.

RESUMEN

At the University of Bristol, we established a novel dissection course to complement our anatomy degree. Students enrolled in this undergraduate course are trained as comparative anatomists, with equal time given to both human and veterinary anatomy. Historically, students opted to dissect either human or veterinary donors as part of the course. To fully reflect the comparative nature of the degree, the dissection course was redesigned so students could dissect both human and veterinary specimens as part of the same course. This facilitated a wide-ranging experience of anatomy, encouraging detailed knowledge of a multitude of species and allowing for multifaceted anatomy graduates to be ready for employment in a wide and competitive job market. Across three iterations of the amended version of the course, median marks ranged from 58.7% to 62.0%, with between 22 and 39 students enrolled. In comparison to the course prior to the introduction of the change, median marks ranged from 59.8% to 62.8%, with between 16 and 24 students enrolled. There was no significant difference between marks before or after the introduction of the concurrently comparative aspect. This paper describes the course, with learning materials and assessments considered, along with some reflection on its value. The course offers benefits to students by widening their perspective on anatomical knowledge and making them more equipped for the job market. It also broadens their understanding of form-function relationships. However, student feedback implied that having the choice between human or veterinary dissection was preferable, and this may outweigh the perceived benefits of the course.

RESUMEN

Human dissections in the current medical curriculum are conducted using a checklist approach to prioritize the exposure of anatomical structures. In this setting, anatomy educators are labored to enhance their engagement during the dissection. To address this issue, we considered the current medical education pedagogies and identified a novel approach of studio-based learning (SBL) for application in a Human Dissection Workshop. This study aimed to (1) evaluate students' perceptions of SBL, (2) appraise the impact of SBL on anatomical knowledge learning, and (3) interpret the results of a validated questionnaire. Workshop participants were recruited from Year 2 medical students at the Chinese University of Hong Kong from the 2020 and 2021 cohorts. Fifty-one students participated in the workshop (N = 24 [2020], N = 27 [2021]), and 50 of them completed the postworkshop questionnaire rated on a 5-point Likert scale. Nineteen items were validated using a factor analysis. The interpretation of the questionnaire results demonstrated the different learning outcomes of the workshop, which included (1) enhancing students' knowledge and spatial understanding of anatomical structures, (2) strengthening students' appreciation of gross pathologies and clinical relevance, and (3) promoting higher-order thinking skills. To our knowledge, this is the first study to introduce SBL in medical education. The successful implementation of the workshop reflects the promising potential of SBL for enhancing human dissection and supplementing the medical curriculum.

RESUMEN

An innovative series of dissections of the canine abdomen was created to facilitate social distancing in the dissection room following COVID-19 restrictions imposed in the UK. In groups of six, first-year veterinary students took turns dissecting selected parts of the canine abdomen while maintaining social distancing and documenting their work with video and photographs. Here, students learned about the canine abdominal anatomy by dissecting, recording the dissections of others in their group, and compiling the recorded material into a collaborative electronic media portfolio (Wiki). An online formative multiple-choice test was created to test students' knowledge of the canine abdominal anatomy. The result analysis showed that although students achieved the learning outcomes only by studying the Wiki, they had better performance in the anatomical areas where they learned through the dissection (p < 0.05). Student performance was very similar in the areas in which they were present in the dissection room and participated in recording the dissection compared with the areas that they effectively dissected (p > 0.05). A qualitative thematic analysis was developed to understand students' opinions via their feedback on this dissection approach. Our results showed that student collaboration and the development of practical skills were the most valued aspects of this dissection teaching initiative. Moreover, these results show that developing a group Wiki has a positive impact on student achievement of learning objectives, with a practical hands-on dissection being fundamental for the optimal learning of the canine abdominal anatomy.

RESUMEN

BACKGROUND: Practicing on the human body was considered extremely relevant for health professionals' education, but a drastic reduction was observed due to an increase in alternative virtual and multimedia means, and, in Italy, also due to a lack of regulation. Italian Law 10/2020 regulates body donation for research and training through an advanced directive for post-mortem body donation. METHODS: A cross-sectional study was carried out to investigate the law knowledge and body donation perception of health students of any degree courses enrolled at the University of Pavia, Italy, in 2021, through ad hoc web questionnaire. RESULTS: 485 students participated to this survey; median age was of 21 years (25th-75th percentiles, 20-23), 73.2% were females, and 62.5% were medical students. Among them 14.9% knew the Italian law 10/2020. Age was the only variable associated with students' knowledge of the law. Further, 8.3% reported the current availability of cadaveric practice, 85.6% of health students acknowledged usefulness of cadaveric practice, with a significant difference between medical and non-medical students (71.4% vs 28.6%, p < 0.001). Overall, 59.7% would donate their body, rising to 62.7% with reference to specific law regulation, with 30.5% and 28.7% undecided, respectively. 51.3% of participants answered not practicing religious faith, 82.9% with Catholic families, without significance on the knowledge of the law. CONCLUSIONS: Poor knowledge of the law compared with great interest and acknowledged cadaveric practice usefulness highlighted the need for better information, especially among health students, where critical discussion could be more valuable. Then, there arises the urgent need to fill the gaps within university studies and syllabuses, to relaunch the central role that cadaveric practice and research had in the education of health professionals. Consequences on basic and specific health students' skills, on health education quality in general, and further on health professionals' expertise must be carefully considered.

RESUMEN

Serious games may resolve problems relating to low motivation in complex medical topics such as anatomy. However, they remain relatively novel introductions to the science of learning, and further research is required to ascertain their benefits. This study describes the overall development and testing of a digital serious boardgame designed to facilitate the rehearsal of musculoskeletal anatomy based on self-determination theory with considerations for the psychological state of Flow. It was hypothesized that students assigned to the intervention game condition would attain higher Flow scores, a measure of engagement and intrinsic motivation, than students assigned to the game-free control, and that the intervention condition would report either superior or non-superior, but not inferior, scores on a surprise recall test. A total of 36 second-year undergraduate medical students participated in the quasi-randomized controlled trial, where the intervention groups went first and randomly drew questions that were mirrored into the control groups. All students were administered an identical 10-question baseline assessment before their interventions, the Short Flow Scale immediately after, and a surprise test four-to-six weeks later. Independent samples t-tests indicated that students of both conditions were of similar baseline knowledge (t = 0.7, p = 0.47), significantly higher Flow scores in the game condition (t = 2.99, p = 0.01), and no significant differences between surprise test scores (t = -0.3, p = 0.75). The game appears to be an appropriate game-based tool for student rehearsal of anatomical education, stemming from a strong theoretical base that facilitates high engagement and intrinsic motivation.

RESUMEN

The COVID-19 Pandemic has conveyed an unprecedented worldwide challenge. Although there is much emphasis on caring for patients and communities, the high incidence of SARS-CoV-2 had seriously disturbed education and calls for prompt as well as serious consideration from educators in medical schools. The necessity to teach and prepare prospective medics, as well as clinicians, has certainly not been as intense as it is currently. The global effects of coronavirus disease 2019 may cause a permanent change in the education of future clinicians. The COVID-19 era presented logistical and practical obstacles and fears for the patients' well-being, taking into consideration the fact that students may be potential channels for the spread of the virus when asymptomatic and may get infected while being in training and attending lectures. This paper discusses the present state of morphological science education, depicting the effect of COVID-19 on learning environments, as well as highlights the probable effects of COVID-19 on medical instruction in the future.

RESUMEN

Understanding the three-dimensional (3D) structure of the human skull is imperative for medical courses. However, medical students are overwhelmed by the spatial complexity of the skull. Separated polyvinyl chloride (PVC) bone models have advantages as learning tools, but they are fragile and expensive. This study aimed to reconstruct 3D-printed skull bone models (3D-PSBs) using polylactic acid (PLA) with anatomical characteristics for spatial recognition of the skull. Student responses to 3D-PSB application were investigated through a questionnaire and tests to understand the requirement of these models as a learning tool. The students were randomly divided into 3D-PSB (n = 63) and skull (n = 67) groups to analyze pre- and post-test scores. Their knowledge was improved, with the gain scores of the 3D-PSB group (50.0 ± 3.0) higher than that of the skull group (37.3 ± 5.2). Most students agreed that using 3D-PSBs with quick response codes could improve immediate feedback on teaching (88%; 4.41 ± 0.75), while 85.9% of the students agreed that individual 3D-PSBs clarified the structures hidden within the skull (4.41 ± 0.75). The ball drop test revealed that the mechanical strength of the cement/PLA model was significantly greater than that of the cement or PLA model. The prices of the PVC, cement, and cement/PLA models were 234, 1.9, and 10 times higher than that of the 3D-PSB model, respectively. These findings imply that low-cost 3D-PSB models could revolutionize skull anatomical education by incorporating digital technologies like the QR system into the anatomical teaching repertoire.

RESUMEN

The pure transfer of face-to-face teaching to a digital learning environment can be accompanied by a significant reduction in the physiological arousal of students, which in turn can be associated with passivity during the learning process, often linked to insufficient levels of concentration and engagement in the course work. Therefore, the aim of this study was to investigate whether students' psychobiological stress responses can be enhanced in the context of anatomical online learning and how increased physiological parameters correlate with characteristics of learning experiences in a digital learning environment. Healthy first-year medical students (n = 104) experienced a regular practical course in Microscopic Anatomy either in face-to-face learning, in passive online learning or in an interaction-enhanced version of online learning. Compared to passive online learning, students engaged in the interaction-enhanced version of online learning displayed a significantly reduced Heart Rate Variability (P 0.001, partial η2 = 0.381) along with a strong increase in salivary cortisol (P 0.001, partial η2 = 0.179) and salivary alpha-amylase activity (P 0.001, partial η2 = 0.195). These results demonstrated that the physiological arousal of students engaged in online learning can be enhanced via interactive teaching methods and pointed towards clear correlations between higher physiological responses and elementary criteria of learning experience such as engagement and attention.

RESUMEN

Binocular disparity provides one of the important depth cues within stereoscopic three-dimensional (3D) visualization technology. However, there is limited research on its effect on learning within a 3D augmented reality (AR) environment. This study evaluated the effect of binocular disparity on the acquisition of anatomical knowledge and perceived cognitive load in relation to visual-spatial abilities. In a double-center randomized controlled trial, first-year (bio)medical undergraduates studied lower extremity anatomy in an interactive 3D AR environment either with a stereoscopic 3D view (n = 32) or monoscopic 3D view (n = 34). Visual-spatial abilities were tested with a mental rotation test. Anatomical knowledge was assessed by a validated 30-item written test and 30-item specimen test. Cognitive load was measured by the NASA-TLX questionnaire. Students in the stereoscopic 3D and monoscopic 3D groups performed equally well in terms of percentage correct answers (written test: 47.9 ± 15.8 vs. 49.1 ± 18.3; P = 0.635; specimen test: 43.0 ± 17.9 vs. 46.3 ± 15.1; P = 0.429), and perceived cognitive load scores (6.2 ± 1.0 vs. 6.2 ± 1.3; P = 0.992). Regardless of intervention, visual-spatial abilities were positively associated with the specimen test scores (η2 = 0.13, P = 0.003), perceived representativeness of the anatomy test questions (P = 0.010) and subjective improvement in anatomy knowledge (P < 0.001). In conclusion, binocular disparity does not improve learning anatomy. Motion parallax should be considered as another important depth cue that contributes to depth perception during learning in a stereoscopic 3D AR environment.

RESUMEN

The cardiac conduction system (CCS) is crucial for regulating heartbeats; therefore, clinicians and comedicals involved in cardiovascular medicine treatment must have a thorough understanding of the CCS structure and function. However, anatomical education of the CCS based on actual dissection and observation is uncommon, although such educational methodology promotes three-dimensional structural understanding of the observed object. Based on previous studies, we examined the CCS structure in the heart of a swine (pig, Sus scrofa domestica) which has been used in the biological, medical and anatomical curricula as science teaching materials, by using macroscopic dissection procedures. Most CCS structures in a young pig heart were successfully identified and illustrated on a macroscopic scale. The atrioventricular bundle (His bundle) was located on the lower edge of the membranous interventricular septum and was clearly distinguished from the general myocardial fibres by its colour and fibre arrangement direction. Following the atrioventricular bundle towards the atrium or ventricle with properly removing the endocardium and myocardium, the atrioventricular node or the right and left bundles appeared respectively. In contrast, the sinoatrial node was not identified. The anatomy of the CCS in young pig hearts was essentially similar to that previously reported in humans and several domestic animals. Our findings of the CCS in young pig hearts are expected to be useful for medical and anatomical education for medical and comedical students, young clinicians and comedical workers.

RESUMEN

Utilization of human material in surgical simulation training has been well-established as an effective teaching method. Despite the value of donor-based surgical simulation training, its application may be hampered by difficulties regarding access to donated bodies. Therefore, the aim of this review is to assess body donation and body acquisition practices with regard to surgical simulation training programs around the world. The results of this review highlight discrepancies regarding body donation practices and surgical simulation programs among continents and countries. The utilization of donor bodies in surgical simulation appears to mirror body donation practices. In countries that rely mostly or exclusively upon unclaimed bodies or executed criminals, there are scant reports of donor-based surgical simulation programs. In countries where willed-body donation is the principal source of human material, there tend to be many surgical simulation programs that incorporate human material as part of surgical training. This review suggests that, in anatomical and surgical education, the utilization of active willed-body donation programs, as opposed to the utilization of unclaimed human bodies, positively corresponds with the development of beneficial donor-based surgical simulation programs. Likewise, donor-based surgical simulation training programs may have an influence on the perpetualization of willed-body donations.
