Which movement turns the palm up?

Which movement turns the palm up?

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

Answer: (A)

Turning the palm up is called supination. This forearm rotation aligns the radius and ulna so the palm faces upward (or forward when the arm is extended in anatomical position). The opposite action is pronation, where the palm faces downward and the radius rotates across the ulna. The other two terms describe foot movements and aren’t about turning the palm: inversion twists the sole inward toward the midline, and eversion twists it outward. So supination is the movement that turns the palm up.
