while intoxicated,a young man falls through a store-front-plate-glass window,severely lacerating his left wrist.in the emergency room,the physician assesses the integrity of the ulnar nerve at the wrist by asking the patient to perform which one of the following maneuvers?
1) oppose the thumb and little finger
2) abduct the little finger
3) flex the little finger
4) adduct the thumb
5) flex the thumb

2) abductor digiti minimi
flexion can be done by flexor digitorum profundus and superficialis

flex the little finger
The ulnar nerve and its branches innervate the following muscles in the forearm and hand:
* In the forearm, via the muscular branches of ulnar nerve:
o Flexor carpi ulnaris
o Flexor digitorum profundus (medial half)
* In the hand, via the deep branch of ulnar nerve:
o hypothenar muscles
+ Opponens digiti minimi
+ Abductor digiti minimi
+ Flexor digiti minimi brevis
o Adductor pollicis
o The third and fourth lumbrical muscles
o Dorsal interossei
o Palmar interossei
* In the hand, via the superficial branch of ulnar nerve:
o Palmaris brevis

do you know latin? if your flexors are intact (forearm ulnar nerve or median nerve), you'll be able to flex your pinkie. however you won't be able to abduct it!
