Which term describes a position toward the tail end of the body?

The term that describes a position toward the tail end of the body is "inferior." In anatomical terminology, "inferior" refers to structures that are situated below or lower than another structure. For example, in relation to the torso, the feet are considered inferior, while the head is superior, meaning it is positioned above the torso.

In contrast, "superior" describes a position that is above another structure. "Medial" refers to being closer to the midline of the body, while "lateral" indicates a position that is farther from the midline. Understanding these directional terms is essential for accurately describing the locations and relationships of different body parts in medical contexts.
