1

pronator teres attachments

> medial epicondyle of humerus> ulnar head on medial coronoid process > both heads insert onto lateral radius

2

pronator teres nerve and artery

> Median n. (c6,7)> ant. ulnar recurrent a.

3

pronator teres action

pronate and weakly flex forarm@ elbow

4

flexor carpi radialis attachments

> medial epicondyle of humerus > inserts onto base of 2nd and 3rd metacarpals

5

flexor carpi radialis nerve and artery

> median n. (c6,7)> radial a.

6

flexor carpi radialis action

flexes and abducts the wrist, pronates hand, flexes forearm

7

palmaris longus attachment

> medial epicondyle of humerus> inserts on palmar aponeurosis

8

palmaris longus action

> weak forearm flexor> pronate and flex forearm

9

flexor carpi ulnaris attach

> medial epicondyle of humerus> olecranon> both heads insert onto the pisciform, hook of hamate, and 5th metacarpal

10

flexor carpi ulnaris nerve and artery

> ulnar n.> post. ulnar recurrent a.

11

flexor carpi ulnaris action

> flex wrist and forarm

12

flexor digitorum superficialis attach

> medial epicondyle> coronoid process of the ulna> oblique line of radius> both insert onto the middle phalanges 2-5

13

palmarus longus nerve and artery

> median n.> post. ulnar recurrent a.

14

flexor digitorum superficialis nerve and artery

> median n.> ulnar a./radial a.

15

flexor digitorum superficialis action

flex middle and proximal phalanges, aids in forearm flex

16

Flexor digitorum profundus attach

> medial/ant. ulna> Distal phalanges of D2-5

17

flexor digitorum profundus nerve and artery

> medial part is ulnar n.> lateral is interosseus of median n.> ulnar a.

18

flexor digitorum profundus action

flex terminal phalanges 2-5 and flex wrist

19

flexor pollicus longus attachments

> radius, coronoid process of ulna> palmar surface of distal thumb phalynx

20

flexor pollicus longus nerve and artery

> median n.> ulnar a.

21

pronator quadrus attachments

> distal ulna> lateral radius

22

pronator quadrus nerve and artery

> median n.> ulnar a.

23

path of ulnar nerve through forearm

> behind medial epicondyle of humerus> btn heads of flexor carpi ulnaris> joins ulnar a. in distal forarm> superfical sensory branch in wrist

24

path of median nerve through forearm

> leaves cubital fossa btn. two heads of pronator teres> courses teep to flexor digitorum superficialis> branches to anterior interosseus> branches to palmar cutaneous branch

25

main branches of radial artery in forearm/hand

> radial recurrent a.> superficial palmar arch> deep arch> palmar carpal a> dorsal carpal a

26

main branches of ulnar artery in forearm

> ant. ulnar recurrent> post. ulnar recurrent> common interosseous to ant. post. interosseous> palmar carpal> dorsal carpal> superficial branch> deep palmar branch

27

extensor retinaculum

thickened antebrachial fascia on dorsum of wrist

28

what is in the carpal tunnel?

> 4 tendons of flexor digitorum superficialis> 4 tendons of flexor digitorum profundus> tendon of flexor pollicus longus> median n.

29

Abductor pollicus brevis attachment

> trapezium and scaphoid> proximal phalynx of thumb

30

abductor pollicus brevis nerve and artery

> median n. and deep ulnar n.> superficial radial a.
