Medial vs Lateral meaning.

• A. Medial means toward the midline.
• B. Lateral means toward the midline.
• C. Medial means toward the back.
• D. Lateral means toward the front.

Answer: (A)

Medial and lateral describe location relative to the body's midline, an imaginary line running down the center. Medial means toward that midline. For example, the nose is medial to the eyes, and the big toe is medial to the little toe. Lateral means away from the midline, toward the outer sides—for instance, the ears are lateral to the eyes, and the little toes are lateral to the big toe. The terms for front and back are anterior (front) and posterior (back), which aren’t about the midline direction.
