Superficial head of pronator teres | |||
Origin | Humeral head: medial epicondyle of the humerus (common flexor tendon) | ||

Artery | Ulnar and radial artery | ||
Innervation | Median nerve | ||
Action | Pronation of the forearm and flexes the elbow | ||
Antagonist | Supinator muscle |
The superficial head of pronator teres is the larger and more superficial of its two origins. It arises from the medial epicondyle of the humerus via the common flexor tendon. It combines with the ulnar head to eventually insert as a common tendon onto a rough impression on the lateral surface of the midshaft of the radius.
