Where does the pronator teres insert?

Explanation:
The muscle that pronates the forearm inserts at the middle of the lateral surface of the radius. It has two heads that originate from the medial epicondyle of the humerus and the coronoid process of the ulna, but the distal tendon reaches the midshaft of the radius on its lateral side. Contraction pulls the radius over the ulna, producing pronation. Its position also gives it a small role in assisting elbow flexion.
