opponens pollicis dist attach.

1st metacarpal - lateral side

1

Opponents policies prox attach

flexor retinaculum and tubercles of scaphoid and trapeium

2

opponens pollicis innervation

recurrent branch of median nerve C8 T1

3

opponens pollicis action

-to oppose thumb, draws first metacarpal medially to center of palm and rotates it medially

4

flexor pollicis brevis prox attachment

flexor retinaculum and tubles of scaphiod and trapezium

5

what muscles share prox attachment of the flexor retinaculum and tubercles of scaphoid and trapezium

opponens pollicis, abductor pollicis brevis, flexor pollicis brevis

6

abductor pollicis brevis prox attachment

flexor retinaculum and tubercles of scaphoid and trapezium

7

what muscles share innervation of recurrent branch of median nerve (c8, t1)

opponens pollicis, abductor pollicis brevis, flexor pollicis brevis

8

abductor pollicis brevis AND flexor pollicis brevis dist attachment sites (share)

thumb - base of proximal phalanx on lateral side

9

adductor pollicis innervation

deep branch ulnar nerve (c8, t1)

10

adductor pollicis prox attach

bases of 2nd and 3rd metacarpals, capitate, adjacent carpals (oblique head - ant surface of shaft of 3rd metacarpal)

11

adductor pollicis distal attach

thumb - base of proximal phalanx on medial side

12

flexor digiti minimi brevis AND opponens digiti minimi prox attach.

hook of hamate and flexor retinaculum

13

abductor digiti minimi and flexor digiti minimi brevis share the same distal attachmment. what is it -

base proximal phalanx of fifth finger - medial side

14

distal attach of oppenens digiti minimi

medial border of fifth metacarpal

15

abductor digiti minimi, flexor digiti minimi brevis and opponens digiti mini are ALL invervated by what nerve -

deep branch of the ulnar nerve (c8, t1)

16

action abductor digiti minimi

abduct fifth finger, assists in flexion proximal phalanx

17

action of flexor digiti minnimi brevis

flexes proximal phalanx of fifth finger

18

action of opponens digiti minimi

brings fifth metacarpal anterior and rotates it, bring into opposition with thumb
