Which term denotes toward the side away from the midline?

• A. Lateral
• B. Medial
• C. Superior
• D. Inferior

Answer: (A)

In anatomy, directional terms describe where something sits relative to the body's center. Lateral denotes toward the side away from the body's midline—the imaginary vertical line down the center. The midline is the reference; anything farther from it is lateral, while anything closer to it is medial. Superior and inferior describe vertical positions (toward the head and toward the feet), not side-to-side. So lateral is the correct term for “toward the side away from the midline.” For example, the ears are lateral to the eyes, and the temporal lobes lie laterally relative to deeper midline structures.
