The ulnar nerve starts from the brachial plexus and the quiz below contains questions related to the pathway it follows through the body. How well do you understand the nerve and its path? Take up the quiz and find out.
- 1.
At the elbow, the nerve goes ______ to the _______ epicondyle of the humerus and _________ to the olecranon process
- A.
Posterior, lateral, medial
- B.
Posterior, medial, medial
- C.
Anterior, medial, lateral
- D.
Anterior, lateral, lateral
Correct Answer
B. Posterior, medial, medialExplanation
The correct answer is posterior, medial, medial. At the elbow, the nerve goes posterior to the medial epicondyle of the humerus and medial to the olecranon process.Rate this question:

- 2.
What muscle does the nerve them follow between and deep to?
- A.
Extensor carpi ulnaris
- B.
Flexor carpi ulnaris
- C.
Extensor carpi radialis longus
- D.
Flexor carpi radialis
Correct Answer
B. Flexor carpi ulnarisExplanation
The correct answer is flexor carpi ulnaris. This muscle is innervated by the ulnar nerve, which runs between and deep to the flexor carpi ulnaris muscle.Rate this question:

- 3.
The nerve then continues over carpal tunnel between which two structures
- A.
Hook of hamate
- B.
Scaphoid tubercle
- C.
Listers tubercle
- D.
Pisiform
Correct Answer(s)
A. Hook of hamate
D. PisiformExplanation
The nerve continues over the carpal tunnel between the hook of hamate and the pisiform. These two structures are located in the wrist. The hook of hamate is a bony projection on the palm side of the wrist, while the pisiform is a small bone located near the base of the palm. The nerve passes between these structures as it travels through the carpal tunnel, which is a narrow passageway in the wrist.Rate this question:

- 4.
The nerve then divides into _______ and ______ and continues into the fingers and hand
- A.
Superficial and lateral
- B.
Deep and medial
- C.
Deep and lateral
- D.
Superficial and deep
Correct Answer
D. Superficial and deepExplanation
The nerve mentioned in the question divides into two branches, one that is closer to the surface of the body (superficial) and another that is deeper within the body (deep). These branches continue into the fingers and hand, allowing for sensory and motor functions in these areas.Rate this question:

- 5.
Select all the muscles that are innervated by the Ulnar nerve
- A.
Extensor carpi ulnaris
- B.
Flexor carpi ulnaris
- C.
Flexor digitorum profundus
- D.
Extensor digitorum
- E.
Hypothenar muscles
- F.
Abductor pollicis
- G.
Pronator teres
- H.
Thenar eminence
Correct Answer(s)
B. Flexor carpi ulnaris
C. Flexor digitorum profundus
E. Hypothenar muscles
H. Thenar eminenceExplanation
The ulnar nerve innervates the flexor carpi ulnaris, flexor digitorum profundus, hypothenar muscles, and thenar eminence. These muscles are all located in the forearm and hand. The flexor carpi ulnaris is responsible for flexing and adducting the wrist. The flexor digitorum profundus flexes the fingers. The hypothenar muscles are a group of muscles located in the palm of the hand that control movement of the little finger. The thenar eminence is a group of muscles located at the base of the thumb that control movement of the thumb.Rate this question:
