Which term describes the direction opposite the midline of the body?

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

Answer: (D)

When we describe body directions, we compare to the midline—the imaginary line down the center of the body. Medial means toward that midline, while lateral means away from it. The term that describes the direction opposite the midline is lateral. Distal and proximal describe distance along a limb from the trunk (distal = farther from the trunk; proximal = closer to the trunk), not direction relative to the midline. So, lateral is the correct concept for describing directions away from the midline.
