Flashcards in Anterior Compartment of forearm Deck (31):
1

antebrachial fascia

fascia on palmar side of hand

2

where do all superficial/intermediate anterior forearm muscles derive from

via what

and what are they

medial epicondyle via common flexor tendon

pronator teres-most lateral

flexer carpi radialis-biggest

palmaris longis-second most medial

flexor carpi ulnaris-most medial

3

pronator teres attachments

humeral head-medial epicondyle of humerous

ulnar head-coronoid process of humorous

both insert into lateral radius (distill to supinator insertion)

4

pronator teres innervaiton

median nerve c6-7

5

pronator teres actions

pronate forarm

weakly flex forearm at elbow

6

flexor carpi radialis attachments

medial epicondyle of humorous

2nd metacarpal (index finger) or possibly middle finger

7

flexor carpi radialis innervation

median nerve c6-7

8

flexor carpi radialis actions

flex and abudct hand at wrist

9

palmaris longis attachments

medial epicondyle of humorous

palmar aponeuorsis

10

palmaris longis innervation

median nerve c7-8

11

palmaris longis actions

tighten palmar aponueris at wrist

weakly flex arm at elbow

12

flexor carpi ulnaris attachments

humeral-medial epicondyle of humorous
ulnar-olecranon

both insert into baee of pisiform bone, hook of hamate, and base of 5th metacarpal

13

flexor carpi ulnaris innervation

ulnar nerve c7-t1

14

flexor carpi ulnaris actions

fle and adduct hand at wrist

15

intermiedate layer things

flexor digitorum superficialis

median nerve right under it

16

flexor digitorum superficialis attachments

humeral-flexor digitorum superficialis
ulnar-coroid process of ulna

both insert into the sides of middle phalanges of the 2nd to 5th digits

17

flexor digitorum superficialis innervation

median nerve c8-t1

18

flexor digitorum superficialis actions

flex at MCP and PIP jints

weakly flex arm at elbox

19

three deep anterior forearm muscles

flexor pollicis longus, flexor digitorum prfundus, pronator quadratus

20

flexor pollicis longus attachments

midanterior surface of radius
and adjucant inerosseous membrane

inserts onto palmar surface of distal phalanx of thumb

21

flexor pollicis longus innervation

median nerve c7-c8

22

flexor pollicis longus actions

flex hand at wrist and flex thump at MCP, IP, and carpometacrpal joint

also abducts hand at wrist

23

flexor digitorum prfundus attachments

originates form two thirds of floor surface of ulna and interrorseous membrane

inserts into palmar surface of distal phalanxes of 2nd and 5th digits

24

flexor digitorum prfundus innervation

median nerve c8-t1

and ulnar nerve c8-t1

25

flexor digitorum prfundus actions

flex hand at wrist

flex 2nd to 5th digits at MCP, PIP, and DIP joints

26

pronator quadratus attachments

anteiror surface of distal quarter of ulna

inserts onto anterior surface of distal quarter of radius

27

pronator quadratus innervation

median nerve c7-8

28

pronator quadratus actions

pronates hand

stabilizes distal radioulnar joint

29

order of finger joints

MCP, PIP, DIP

30

ulnar artery path

what runs with it

divides early into common interosseous artery
-then divide into anterior and postiroor interosseous arteries
-anterior lies on top of iteroosseous membrane

ulnar nerve

31

radial artery path

where located

what runs with it

deep to brachioradialis

superficial branch of radial nerve
