The usual relationship between the nerves, arteries and tendons (radial side to ulnar side) at the volar aspect of the wrist is as follows:

• Radial artery
• Flexor carpi radialis
• Median nerve
• Palmaris longis
• Ulnar artery
• Ulnar nerve
• Flexor carpi ulnaris.

The ulnar artery is a larger vessel than the radial artery.
