Adduction of thumb.

Injury to the Ulnar nerve

  • Ulnar nerve is most commonly injured at the elbow, where it lies behind the medial epicondyle and at the wrist where it lies in front of flexor retinaculum.
  • In high ulnar nerve injury at or proximal to elbow, all the muscles supplied by the ulnar nerve in the forearm and hand are paralyzed whereas in low ulnar nerve palsy, there is sparing of the forearm muscles (in flexor carpi ulnaris and flexor digitorum profundus). Sensory deficit are same in both high & low ulnar nerve injury.

Q. 2

Deep branch of ulnar nerve supplies?

 A

Adductor Pollicis,1st lumbrical

 B

Flexor digitorum superficialis, Palmer brevis

 C

1st lumbrical, 3rd lumbrical

 D

3rd lumbrical, Adductor Pollicis

Q. 2

Deep branch of ulnar nerve supplies?

 A

Adductor Pollicis,1st lumbrical

 B

Flexor digitorum superficialis, Palmer brevis

 C

1st lumbrical, 3rd lumbrical

 D

3rd lumbrical, Adductor Pollicis

Ans. D

Explanation:

“Flexor digitorum superficialis is supplied by median nerve”

“The 1st and 2nd lumbricals are supplied by median nerve”

Ulnar nerve in hand is divided into deep and superficial terminal branches. Deep branch give further muscular branches to muscle of hypothenar eminences( abductor digiti minimi, flexor digiti minimi and opponens digiti minimi), medial two lumbrical (3rd and 4th), 8th interossei, adductor pollicis and occasionally deep head of the flexor pollicis brevis. Articular branch from deep terminal branch supplies wrist joint.

Superficial terminal branch gives muscular branch to palmaris brevis and cutaneous branches which supplies medial one and half fingers with nail beds.

Q. 5

Deep branch of ulnar nerve supplies all except ‑

 A

Adductor pollicis

 B

Abductor digiti minimi

 C

Flexor digiti minimi

 D

Opponens pollicis

Q. 5

Deep branch of ulnar nerve supplies all except ‑

 A

Adductor pollicis

 B

Abductor digiti minimi

 C

Flexor digiti minimi

 D

Opponens pollicis

Ans. D

Explanation:

Various branches of ulnar nerve are :‑

A) In arm : No branch.

B) In forearm : There are following branches :‑

1)  Muscular : In proximal part of forearm it supplies flexor carpi ulnaris and medial half of flexor digitorum profundus.

2)  Cutaneous : There are two cutaneous branches in forearm:-

i)   Palmar cutaneous branch : Supplies skin over the hypothenar eminence.

ii)  Dorsal (posterior) cutaneous branch : Supplies skin over medial 1/3 of dorsum of hand and dorsal surface of medial 11/2 fingers.

C) In hand : Ulnar nerve enters the palm by passing superficial to flexor retunuculum and divides into two terminal branches :‑

1)   Superficial terminal branch : It supplies palmaris brevis and skin of palmar surface of medial 11/2 fingers.

2)  Deep terminal branch : It supplies adductor pollicis, all interossei, medial two (3″1 & 4th)lumbricals and all hypothenar muscles except palmaris brevis (i.e. abductor digiti minimi, flexor digiti minimi, opponens digiti minimi).
