Which term describes a structure farther from the body's surface?

• A. Superficial
• B. Deep
• C. Inferior
• D. Medial

Answer: (B)

Distance from the body's surface is described with terms like superficial and deep. Superficial means near the surface, while deep means farther away from the surface, toward the interior. So the term that describes a structure farther from the surface is deep. For example, skin is superficial; muscles lie deeper under the skin, and bones are even deeper still. The other terms describe position in relation to height or the midline (inferior and medial) and don’t address how close something is to the surface.
