What term is used for a human body intended solely for scientific study and dissection?

The term that specifically refers to a human body intended for scientific study and dissection is "cadaver." This word is commonly used in medical and anatomical contexts to describe bodies that are donated for the purposes of education and research. Cadavers play a crucial role in medical training, allowing students and professionals to gain hands-on experience in anatomy, surgical techniques, and pathological studies.

In contrast, "corpse" is a more general term that refers to a dead body but does not necessarily imply that it is being used for research or study purposes. "Remains" typically refers to the leftover parts of any deceased organism, which can encompass a broader range of contexts, not limited to scientific examination. "Fossil," on the other hand, describes preserved remnants or impressions of ancient organisms that have been buried and transformed over time, and is unrelated to the study of human anatomy in the present day.
