Anatomy & Physiology: Muscles—Pronator Teres.
Structure.
- Origin: medial epicondyle of humerus, and coronoid process of ulna.
- Insertion: midlateral surface of radius.
Function.
- Concentric action: pronates forearm at radioulnar joints and weakly flexes forearm at elbow joint.
- Reverse mover action: pronation of forearm; elbow flexion.
- Eccentric action: controls/restrains/slows elbow supination and elbow extension.
- Isometric action: stabilization of the elbow.
- Innervation: median nerve.
- Arterial supply: ulnar artery, radial artery.
Clinical Significance.
