| Question | Answer |
|---|---|
| 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 |
| flexor carpi ulnaris insertion | pisiform hook of hamate & 5th metacarpal |
| action of flexor carpi ulnaris | flex or aduct hand at wrist |
| adduction | ulnar deveation |
| 2nd layer ant forearm | flexor digitorum superficialis |
| has 4 tendons | flexor digitorum superficialis |
| origin- medial epi condyle of the humerous ulna and radius | flexor digitorum superficialis |
| flexor digitorum superficialis action | flex proximal phalanges wrist& hand |
| insertion flexor digitorum superficialis | middle phalanges og digits 2nd -5th |
| 3rd layer | flexor pollicis longus |
| origin radius & interosseous membrane | flexor pollicis longus |
| flexor pollicis longus insertion | under flexor retinaclum to distal phalanx of the thumb |
| action flexor pollicis longus | flex distal phalanx of the thumb |
| flexor pollicis longus | flick your bic muscle |
| 1 tendon | flexor pollicis longus |
| 3rd layer | flexor digitorum profundus |

| flexor digitorum profundus | insertion- base of distal phalanges of the hand 2nd-5th digits |
| action flexor digitorum profundus | flex hand at wrist make as fis flex poximal middle and distal |
| 4 tendons | flexor digitorum profundus |
| 4th layer | pronator quadratus |
| origin ulna | pronator quadratus |
| insertion radius | pronator quadratus |
| common innervation for the flexors | median nerve |
| which layer has 4 muscles | 1st layer |
| which layer has 2 muscles | 3rd layer |

| what are the 2 poximal bones that make up the border | scaphoid & pisiform |
| what two distal bones make up the border | trapezium & hamate |
| guyon tunnel | bordered by poximal pisiform and distal hamate |
| ulnar nerve and ulnar artey run through | the guyon tunnel |
