Which term is used for rotating the forearm so the palm faces downward/backward from the anatomical position?

• A. Flexion
• B. Evasion
• C. Pronation
• D. Supination

Answer: (C)

Pronation. This describes rotating the forearm so the palm turns to face downward from the anatomical position. In this position the forearm bones (radius and ulna) are aligned parallel; pronation causes the radius to cross over the ulna, turning the palm toward the ground (posteriorly). The opposite movement is supination, which turns the palm to face upward. Flexion is bending a joint, and eversion is a movement of the foot, not the forearm.
