The **ulnar head** of the pronator teres arises from the medial aspect of the coronoid process. The **humeral head** arises from the common flexor origin. The ulnar head works alongside the humeral head, which originates from the medial epicondyle of the humerus, to assist in pronating the forearm and flexing the elbow.
