Rotation of the forearm that turns the palm down, rotating the radius on the ulna.
Detail
Pronation is rotation on the axis of bone, specifically applied to the forearm, as in turning the hand down by rotating the radius on the ulna. At the end of the movement the palms should face away from you. It is a function of the brachioradialis. Source attributes the movement terminology to Thompson (1989); the radioulnar joint movement diagram is from Harter (1991).

- End position: palms face away from you.
- Produced (in part) by the brachioradialis.
