If the forearm rotates so the palm faces downward, what term describes this motion?

Explanation:
Pronation describes the forearm rotation that brings the palm facing downward. This movement occurs at the radioulnar joints as the radius rotates over the ulna, turning the palm from a forward-facing position toward the back or bottom. Supination is the opposite action, turning the palm upward or forward. Flexion would change the angle of a joint (like bending the elbow or wrist), not the orientation of the palm, and eversion refers to turning the sole of the foot outward, not a forearm motion.
