Ulnar Nerve - Hand

Hand

After it travels down the ulna, the ulnar nerve enters the palm of the hand through the Guyon's Canal. The ulnar nerve and artery pass superficial to the flexor retinaculum, via the ulnar canal.

The course of the ulnar nerve through the wrist contrasts with that of the median nerve, which travels deep to the flexor retinaculum of the hand and therefore through the carpal tunnel.

Here it gives off the following branches:

• Superficial branch of ulnar nerve
• Deep branch of ulnar nerve
