The belly on the medial aspect was larger and was arising from the medial margin of the olecranon process, proximal two thirds of posterior border of ulna, an aponeurosis which is common for FCU, extensor carpi ulnarismuscle and flexor digitorum profundus muscle and intermuscular septum between it and flexor digitorum superficialis muscle. The belly on the lateral side was smaller and was taking its origin from the medial humeral epicondyle along with the other superficial forearm flexors (Figure 1).
