supination
Quick Summary
Supination is a physiological term describing the rotation of the forearm and hand so that the palm faces forward or upward. This movement is primarily facilitated by the supinator muscle located in the posterior compartment of the forearm, with assistance from the biceps brachii. A corresponding movement can occur in the foot and leg, where the foot rolls outward, elevating the arch. The opposite of supination is pronation, where the wrist rotates to face the palm downward.12
