Question 1

Question
Regarding pronator teres which of the following statements is correct?
Answer
  • It forms the lateral border of the cubital fossa
  • It arises from the coronoid process and lateral epicondyle.
  • The Median nerve passes deep to both heads
  • It is the most lateral of the superficial flexors of the forearm

Question 2

Question
Regarding the radial nerve which statement is incorrect?
Answer
  • It passes anterior to the lateral epicondyle of the humerus
  • Sensory loss from injury to the superficial radial nerve will usually result in loss of sensation over the entire thumb
  • It is the larger terminal branch of the posterior cord of the brachial plexus
  • Injury to the radial nerve from fracture of the shaft of the humerus will result in wrist drop

Question 3

Question
Regarding the blood supply of the forearm
Answer
  • The radial artery is the larger of the terminal branches of the brachial artery
  • The radial artery runs under brachialis as it leaves the cubital fossa
  • The radial artery has just one named branch proximal to the carpal braches
  • The radial artery has no involvement in the elbow anastomotic network

Question 4

Question
The median nerve
Answer
  • Supplies flexor carpi ulnaris and half of flexor digitorum profundis
  • Gives rise to most of its braches in the upper arm
  • May be compressed between the two heads of pronator teres
  • Enters cubital fossa lateral to the brachial artery

Question 5

Question
Supination of forearm with the elbow extended is brought about mainly by?
Answer
  • Biceps brachii
  • Supinator
  • Brachioradialis
  • Brachialis

Question 6

Question
At what bony landmark of the humerus is the ulnar nerve vulnerable to damage?
Answer
  • Medial epicondyle
  • Greater tubercle
  • Lateral epicondyle
  • Lesser tubercle

Question 7

Question
Which muscle does the ulnar nerve pierce in the forearm?
Answer
  • Flexor carpi radialis
  • Flexor carpi ulnaris
  • Flexor digitorum superficialis
  • Pronator teres

Question 8

Question
What is the action of anconeus?
Answer
  • Abducts the ulna in pronation
  • Extension of the wrist
  • Supination of the forearm
  • Flexion of the elbow

Question 9

Question
What is the common site of origin for posterior forearm muscles?
Answer
  • Medial epicondyle
  • Lateral epicondyle
  • Olecranon
  • Deltoid tubercle

Question 10

Question
