1st layer of the forearm | pronator teres flexor carpi ulnaris flexor carpi radialis plamaris longus |
common origin of the flexor carpi ulnaris, flexor carpi radialis,palmaris longus | medial epicondyle of the humerous |
origin of th pronator teres | medial epicondyle of the humerous and coronoid of the ulna |
insertion of pronator teres | shaft of the radius |
action of the pronator teres | pronate the forarm |
flexr carpi radialis insertion | base of second metacarpal |
action flexor carpi radialis | flex hand at wrist, abduction |
abduction | radial deveation |
palmaris longus insertion | flexor retinaculum, palmer aponeurosis |
action palmaris longus | felex hand at wrist |
palmaris longus | weak flexor |
