Which term means toward or at the midline of the body?

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

Answer: (A)

Toward or at the midline of the body is described as medial. The midline is the imaginary vertical line down the center that divides the body into left and right halves, so medial structures lie closer to that line. In contrast, lateral means toward the sides away from the midline. Proximal and distal describe distance along a limb from the trunk—proximal is nearer to the trunk, distal farther away. This helps you see why medial is the correct term for “toward the midline.” For example, the nose is medial to the cheeks, while the ears are lateral to the nose.
