What term is used to describe a position that is below or toward the lower end of the spine?

The term "caudal" refers to a position that is below or toward the lower end of the spine. In anatomical terms, "caudal" is often used to describe structures that are situated towards the tail or lower part of the body. This contrasts with the term "superior," which indicates a position above or towards the head, while "superficial" refers to a position closer to the surface of the body, and "deep" indicates a position further away from the surface. Understanding these directional terms is essential in anatomy as they provide a clear and standardized way to describe locations and relations of different body parts. Thus, "caudal" accurately captures the relative position of something that lies lower in the body’s structure.
