Document Summary
Superficial flexors: pronator teres, flexor carpi radialis (fcr, palmaris longus, flexor carpi unlaris (fcu) Pronator teres, fcr, and palmaris longus are innervated by the median nerve, while fcu is innervated by the ulnar nerve. These muscles are attached to the medial epicondyle, and share a common flexor tendon. There are also various fascia and intermuscular septa that allow for additional attachment sites. Has two heads of origin that form a single muscle belly. 4 tendons come from the muscle belly, which pass under the flexor retinaculum, and along the digits via the sides of the middle phalanx of the 4 fingers (thumb not included) Deep flexors: flexor digitorum profundus (fdp, flexor pollicis longus (fpl, pronator quadratus. Similar to fds, fdp ends in 4 tendons, which insert into the bases of the distal phalanges of the 4 fingers (thumb not included) Medial epicondyle and medial border of the coronoid process of the ulna.
