is created by the wrist bones on the bottom and a ligament over the top. The median nerve runs through the tunnel along with the flexor tendons to the wrist. Pressure within the tunnel can compromise the nerve and lead to carpal tunnel syndrome.

Channel on the planner side of the wrist formed by the irregular small bones of the wrist and a tough ligament stretched across it. Through the carpal tunnel pass the flexor tendons of the fingers tendons of the fingers, the median nerve, and some blood vessels.

A narrow rigid passageway of ligament and bones at the base of the hand which houses the median nerve and tendons. (Neurology)

The bony, narrow passage at the intersection of the hand and wrist on the same side of the palm of the hand. The median nerve and tendons pass through this tunnel to the thumb, index, and middle fingers.

Space under a ligament in wrist through which the median nerve enters the palm of the hand.

A small passage located below the wrist at the heel of the hand through which the major nerve to the hand, the median nerve, as well as tendons that bend the fingers pass

In the human wrist there is a sheath of tough connective tissue (the flexor retinaculum) which envelopes and protects several structures. The carpal tunnel is the space between this sheath (above) and the bones (below) making up the wrist and hand (carpal bones).
