Ulnar artery, ulnar nerve and cutaneous branch of median nerve passes over the flexor retinaculum. Palmar carpal ligament and palmar aponeurosis runs deeper through it. Flexor carpi radialis is present on the radial side, thr tendon of palmaris longus and flexor carpi ulnaris is attached to the surface of the flexor retinaculum and short muscles of thumb and little finger originates from the flexor retinaculum.
