Which term describes turning the palm to face anteriorly or superiorly?

Explanation:
Turning the palm to face anteriorly or superiorly is supination. This movement occurs when the radius rotates around the ulna so the palm faces forward in the anatomical position, and it can also orient the palm upward (superiorly) depending on the forearm’s orientation. In supination, the radius and ulna lie parallel rather than crossed, which is the opposite arrangement seen in pronation, where the radius crosses over the ulna and the palm faces posteriorly. Muscles like the biceps brachii and the supinator drive this action, especially when the elbow is flexed, with the supinator contributing when the elbow is extended. The other terms describe different motions: circumduction is a circular movement at a joint, and dorsiflexion refers to lifting the foot upward at the ankle.
