Which term best describes a body part that is located further from the trunk?

The term that best describes a body part located further from the trunk is "distal." In anatomical terminology, "distal" refers to a position that is away from the point of reference, typically the trunk or the main mass of the body. This is particularly relevant in describing limbs; for example, the fingers are distal to the wrist, meaning they are further away from the central part of the body.

This concept is contrasted with "proximal," which indicates a position that is closer to the trunk or point of attachment. Meanwhile, "superior" and "inferior" are directional terms related to vertical positioning; "superior" means above another structure, and "inferior" means below. Therefore, "distal" is the most accurate choice for describing a body part located further from the trunk.
