What describes parts of the body that lie further from the midline?

The term that accurately describes parts of the body that lie further from the midline is "lateral." In anatomical terminology, the midline is an imaginary line that divides the body into right and left halves. Parts of the body that are located away from this midline are considered lateral. For example, the arms are lateral to the torso, meaning they are situated further from the center of the body.

In contrast, "medial" refers to structures that are closer to the midline, while "proximal" and "distal" are terms used to describe the position of limbs in relation to the trunk. "Proximal" indicates a position that is closer to the trunk or point of attachment, whereas "distal" indicates a position further away from the trunk or point of attachment. Thus, when identifying structures that lie further from the midline, "lateral" is the appropriate term.
