Question

Which nerve is most likely to be injured by fractures or dislocations of the elbow (or by an extra hit to the "funny bone")?

a) Ulnar nerve
b) Radial nerve
c) Median nerve
d) Brachial plexus

Answer 1

The ulnar nerve is the most likely nerve to be injured by fractures or dislocations of the elbow or by an extra hit to the 'funny bone.'

Step-by-step explanation:

The nerve that is most likely to be injured by fractures or dislocations of the elbow is the ulnar nerve. The ulnar nerve runs along the inside of the elbow, close to the surface of the skin, which is why it is commonly referred to as the 'funny bone.' When the elbow is hit in a specific way, such as with direct force or from repetitive motions, the ulnar nerve can become compressed or irritated, resulting in pain, numbness, or tingling sensations in the arm and hand.
