Cadaver dissection has become the gold-standard for anatomical education in US medical schools. Ethical issues regarding cadavers may not be as obvious as in living patients, which can lead to their potential neglect in medical school curricula. In this study, we assessed the different ethical concerns (ECs) of medical students regarding cadavers in the gross anatomy lab (GAL), gathered student information, including self-reported academic performance (AP) in the GAL, and determined the best predictors for a student's EC.
