Which term refers to the back part of the body?

• A. Pronation
• B. Prone
• C. Posterior
• D. Medial

Answer: (C)

Understanding directional terms helps describe where something is on the body. Posterior means the back side or rear surface, the opposite of anterior which refers to the front. This makes it the correct term for the back part of the body. For comparison, prone describes a body position (lying face down); pronation is a rotational movement of the forearm or foot; medial describes a location toward the midline, not the back. So posterior best conveys the back aspect.
