cadaver

A cadaver is a dead human body that is used for medical education, training, and research. In medical schools, cadavers provide hands-on experience with human anatomy, enabling dissection, identification of structures, and rehearsal of surgical techniques. Cadavers are also used in biomedical research, pathology training, and the development of medical devices. The term emphasizes the educational or research context, though some institutions prefer phrases like body donor to reflect consent and donation.

Etymology and usage: The word cadaver derives from the Latin cadāver, meaning that which has fallen, from cadere, “to fall.” In English, the term has long been associated with anatomical contexts, but many organizations now use alternative terms such as body donor to underscore voluntary participation and consent.

Sources, consent, and ethics: Cadavers are typically obtained through body donation programs, hospital-based programs, or research donations, with informed consent from the donor or their family. Legal and ethical frameworks regulate procurement, handling, preservation, use, and disposal; donors may choose embalming or other preservation methods. Institutions maintain documentation, consent records, and oversight by ethics committees or institutional review boards to protect privacy and ensure appropriate use.

Handling, storage, and disposition: Cadavers are stored and prepared under biosafety guidelines and with regard for dignity and cultural sensitivities. After instructional use, remains are typically cremated or buried, in accordance with donor wishes, institutional policy, and applicable laws.
