Which nerve is associated with carpal tunnel syndrome?

• A. Radius
• B. Ulnar nerve of the wrist
• C. Median nerve of the wrist
• D. Head of the ulna

Answer: (C)

Carpal tunnel syndrome is primarily associated with the median nerve. This condition occurs when the median nerve, which runs through the wrist and into the hand, becomes compressed within the carpal tunnel. The carpal tunnel is a narrow pathway on the palm side of the wrist, and it is surrounded by bones and ligaments. As a result of this compression, individuals often experience symptoms like numbness, tingling, and weakness in the hand and fingers, particularly in the thumb, index, middle finger, and part of the ring finger.

The median nerve is responsible for the sensation in these areas as well as controlling some of the small muscles at the base of the thumb. Understanding the anatomy and function of the median nerve is crucial for diagnosing and treating carpal tunnel syndrome effectively.
