Which term describes away from the midline?

• A. Medial
• B. Proximal
• C. Distal
• D. Lateral

Answer: (D)

Describing location in the body uses directional terms relative to the midline, which runs down the center. Structures toward the midline are medial, while structures away from the midline are lateral. Proximal and distal describe how close a structure is to the trunk along a limb (proximal = closer to the trunk; distal = farther from the trunk), not side-to-side position. So when you mean something is away from the midline, you’re talking about its lateral position—on the outer side of the body. For example, the ears are on the lateral sides of the head, whereas the nose is near the midline.
