Marieb Language of Anatomy Practice Exam

In anatomy, depth from the body surface is described with simple terms: superficial means near the surface, while deep means farther from the surface. Proximal and distal describe distance along a limb from the trunk, not depth. So for the phrase “away from the body surface,” the best match is deep, because it indicates structures that lie beneath the surface layers (for example, muscles and bones are deep to the skin, which is superficial). That contrast helps you see why deep is correct.
