Document Summary

Forearm flexors (lateral medial; ventral view: pronator teres (blue, flexor carpi radialis (yellow, palmaris longus (green, flexor carpi ulnaris (red) Flexor carpi ulnaris: origin: medial epicondyle of humerus, insertion: pisiform, hook of hamate & base of 5th metacarpal, passes under flexor retinaculum, function: elbow flexion, wrist flexion & adduction. Palmaris longus: origin: medial epicondyle of humerus, insertion: palmar aponeurosis & flexor retinaculum, function: elbow flexion, wrist flexion. Flexor carpi radialis: origin: medial epicondyle of humerus, insertion: 2nd & 3rd metacarpals, passes under flexor retinaculum, function: elbow flexion, wrist flexion & abduction. Pronator teres: origin: medial epicondyle of humerus & coranoid process of ulna, insertion: midlateral surface of radius, function: pronation of forearm, assists with elbow flexion.
