If a body part is located away from the origin of attachment to the trunk, what is the correct term?

The term that describes a body part located away from the origin of attachment to the trunk is "distal." In anatomical terminology, "distal" is used to indicate that a structure is farther from the point of attachment, typically the trunk or the central part of the body. For instance, if referring to the limbs, the fingers are distal to the wrist; they are farther away from the point where the limb attaches to the body.

In contrast, "proximal" refers to being closer to the trunk or point of attachment, which is the opposite of distal. The terms "medial" and "deep" pertain to different spatial relationships. "Medial" refers to being closer to the midline of the body, whereas "deep" describes a position that is more internal, away from the surface of the body. Thus, when discussing the relative position of body parts in relation to their attachment to the trunk, "distal" is the accurate term to indicate a position farther from that point.
