Multiple Choice

The heart is _____ to the arm.

Explanation:
The main idea is understanding how anatomical directional terms describe position relative to the body's midline. The heart sits toward the middle of the body, while the arms extend outward to the sides. So the heart is medial to the arm. Lateral would mean toward the outer side, which isn’t correct here. Distal means farther from the trunk, which doesn’t describe the heart’s relation to the arm. Proximal could describe closeness to the trunk, but the clearest description in this context is medial.
