Which of the following terms describes a body used for medical study or education?

The term that describes a body used for medical study or education is "cadaver." A cadaver is specifically utilized in medical schools and research settings for teaching anatomy, surgical skills, and other scientific studies. This term emphasizes the intentional use of the body for educational purposes, distinguishing it from more general terms like "corpse" or "remains," which do not imply usage for study.

In the context of medical education, cadavers are invaluable for providing hands-on experience, allowing students and professionals to learn about human anatomy in a direct and tangible way. The use of cadavers is foundational in training healthcare professionals, as it enhances understanding of human biology and the complexities of the human body.

Other terms mentioned, such as "corpse" and "remains," refer more broadly to a deceased body without the specific connotation of educational use. "Specimen," while it can refer to a sample used for analysis, does not necessarily imply the whole body and can pertain to any part of an organism used for study. Thus, "cadaver" is the most precise term in this context.
