Flashcards in palm of hand Deck (39):
1

palmar aponeruosis

distal attachment of palmaris longs

covers central compartment of hand

2

palmaris longus attachments

medial epicondyle of humorous

inserts into palmar aponeurosis

3

palmaris longus innervation

median nerve c7-8

4

palmaris longus actions

tighten palmar aponeurosis at wrist

weakly flex arm at elbow

5

thenar emminience

what is it madeof
-what do these look like

muscular swelling at base of thumb

flexor policis brevis-most medial-mostly under flexor pollicis brevis

abductor policis brevis-fattest,most superior, 2nd most medial

opponens pollicis-inferior to abductor pollicis longus and most lateral

6

hypothenar eminence

muscular swlling at base of pinky

abductor digiti minimi-most medial

flexor digititi minimi previs-more lateral to abductor digiti minmi

palmaris brevis-largest-more superficial than other two

7

Ulnar nerve and artery

position to each other

where do they pass

nerve is medial to artery

pass lateral to pisiform bone

8

superficial palmar arterial arch

distal branch of ulnar artery

9

terminal division of ulnar nerve

deep -motor

suerficial-sensory

10

whats under flexor retinaculum

-what happens if you continue on path

carpal tunnel

9 tendons and median nerve

median nerve becomes recurrent branch when enters thenar muscles

11

FDS tendon and FDP tendon releationship

FDS splits and attaches to sides of second phalanx to allow FDP tendon to reach distal phalanx

12

flexor digitorum superficialis attachments

humorous head-medial epicondyle
ulnar head-coronoid process

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

13

flexor digitorum superficialis innervation

median nerve c8-t1

14

flexor digitorum superficialis actions

flex hand at wrist

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

weakly flex forarm at elbow

15

flexor digitorum profundus attachments

two thirds of flexor surface of ulna and from interosseous membrane

inserts into palmar surface of distal phalanges of 2nd to 5th digits

16

flexor digitorum profundus innervtion

median nerve and ulnar nerve
both c8-t1

17

flexor digitorum profundus actions

flex hand at wrist

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

18

lumbricals attachments

1st-radial side of tendon of flexor digitorum proudness
-goes to dorsal digital expansion of 2nd digit

2nd originates from radial side of tendon of flexor digitoum profudus
-inerts into dorsal digital expansion of 3rd digit

3rd lumbrical-possiblly two heads that originate from medial and lateral sides of tendon of flexor digitorum profudus
-inserts onto dorsal ditigal expansion of 4th digit

4th-possbily two heads from medial and lateral sides of tendon of flexor digitorum proudness
-inserts onto dorsal digital expansion of 5th digit

19

lumbricals innervation

1st/2nd-median nerve c8-t1

3rd/4th-ulnar nerve c8-t1

20

lumbricals actions

flex 2nd to 5th digits at MCP joints

extend 2nd to 5th digits at PIP and DIP joints

21

abductor pollicis brevis attachemnts/where is it

in thenar comparment

originates from scaphoid and trapezium bones and from flexor retinaculum

inserts into base of proximal phanlax of thumb via radial sesamoid

22

abduct thumb at CMC joint

24

flexor pollicis brevis where is it/attachments
