Which movement turns the palm downward?

• A. Supination
• B. Pronation
• C. Circumduction
• D. Rotation

Answer: (B)

This question is about turning the hand and forearm. Pronation is the movement that turns the palm downward. It happens when the radius rotates over the ulna, so the palm faces the floor (posteriorly in anatomical terms). Supination is the opposite, turning the palm upward or anterior. Circumduction describes a circular, multi-directional movement, not just turning the palm. Rotation refers to turning around an axis (internal or external) and isn’t limited to the palm’s orientation.
