Median nerve injury typically causes sensory loss in which digits?

The key idea is the sensory distribution of the median nerve in the hand. The median nerve supplies sensation to the lateral (radial) three and a half digits on the palm—the index, middle, and the radial side of the ring finger (and includes the thumb as well in the full distribution). In median nerve injury, sensory loss is felt in those digits where the nerve provides sensation. Among the options, the set that best reflects the typical pattern tested is the index and middle digits together with the radial side of the ring finger, since these are the digits most consistently involved in median nerve sensory loss. The little finger is supplied mainly by the ulnar nerve, and an injury requiring loss across the entire hand would imply more widespread nerve involvement. While the thumb is also typically affected in median nerve injuries, the option that lists the index, middle, and radial side of the ring finger best matches the classic sensory loss pattern described in many exams.
