What term refers to something located away from the surface or toward the inside?

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

Answer: (B)

Depth from the body surface is described with deep versus superficial. The phrase “away from the surface or toward the inside” points to deep, which means structures that are farther from the outer surface or closer to the interior. For example, bones are deep to the skin, while a skin layer or fat sits more superficially. The other terms describe different notions: medial and lateral relate to the midline of the body (toward or away from the midline, respectively), and superficial means near the surface. So the best term for something away from the surface or toward the inside is deep.
