Which movement describes turning the palm so the face of the hand is downward?

• A. Pronation
• B. Supination
• C. Inversion
• D. Eversion

Answer: (A)

Pronation is the rotation of the forearm that turns the palm to face downward. As the radius crosses over the ulna, the palm that starts facing forward in the anatomical position ends up facing downward. Supination is the opposite, bringing the palm to face upward. Inversion and eversion describe movements of the foot: inversion turns the sole toward the midline, eversion turns it away. So turning the palm to face downward describes pronation.
