Which term describes turning the forearm so the palm faces inferiorly or posteriorly?

Explanation:
Turning the forearm so the palm faces inferiorly or posteriorly is pronation. In this rotation, the radius crosses over the ulna, and the palm ends up facing downward toward the floor or toward the back when the arm is at the side. Supination is the opposite movement—turning the palm to face anteriorly. Inversion relates to turning the sole of the foot inward, not the forearm. Rotation is a general term for turning about an axis, not specific to forearm orientation. So the described movement is pronation.
