MBBS QUESTION #10179
Question 1
Compression of the median nerve within the carpal tunnel (carpal tunnel syndrome) classically causes sensory disturbance over which part of the hand?
  • Little and ring fingers only
  • Palmar aspect of the thumb, index, middle, and lateral half of the ring finger✔️
  • All five digits equally, dorsal and palmar
  • Dorsal aspect of the hand only
Correct Answer Explanation
The median nerve enters the palm through the carpal tunnel and supplies palmar sensation to the thumb, index, middle, and radial half of the ring finger; compression here (carpal tunnel syndrome) produces pain and paraesthesia in this distribution, often worse at night.
