Which term describes rotation of the radius about the ulna in the forearm, causing the palm to face posteriorly or inferiorly?

Pronation is the rotation of the forearm around the ulna that turns the palm to face posteriorly or downward. In this movement the radius crosses over the ulna at the radioulnar joints, allowing the hand to rotate. The action is produced mainly by the pronator muscles, such as pronator teres and pronator quadratus. This is the opposite of supination, where the palm faces anteriorly; circumduction describes a circular arc of motion, and elevation refers to lifting a body part upward.
