| Flexor carpi radialis |
Common flexor origin and surrounding fascia |
Front of bases of second and third metacarpals |
Median |
Flexes and abducts the carpus, part flexes the elbow and part pronates forearm |
| Palmaris longus |
Common flexor origin |
Apex of palmar aponeurosis |
Median |
Wrist flexor |
| Flexor carpi ulnaris |
Small humeral head arises from the common flexor origin and adjacent fascia. Ulnar head comes from medial border of olecranon and posterior border of ulna |
Pisiform and base of the fifth metacarpal |
Ulnar nerve |
Flexes and adducts the carpus |
| Flexor digitorum superficialis |
Long linear origin from common flexor tendon, adjacent fascia and septa and medial border of the coronoid process |
Via tendons in the fibrous flexor sheath. At the level of the metacarpophalangeal joint each tendon split into two, these bands pass distally to their insertions |
Median |
Flexor of metacarpophalangeal joint and proximal interphalangeal joint |
| Flexor digitorum profundus |
Upper two thirds of the medial and anterior surface of the ulna, medial side of the olecranon, medial half of the interosseous membrane |
Via tendons that lie deep to those of flexor digitorum superficialis to insert into the distal phalanx |
Medial part= ulnar, lateral part=anterior interosseous nerve |
Flexes the distal interphalangeal joints and the wrist |
