Transverse section at the wrist. The median nerve is colored yellow. The<unk>  tunnel consists of the bones and transverse<unk>  ligament. The median nerve can be compressed by a decrease in the size of the canal, an increase in the size of the contents (such as the swelling of tissue around the flexor tendons), or both. When the pressure builds up inside the tunnel, it damages the median nerve (median neuropathy). As the median neuropathy gets worse, there is loss of sensibility in the thumb, index, long, and thumb side of the ring finger. As the neuropathy progresses, there may be first weakness, then to atrophy of the muscles of thenar eminence (the flexor pollicis brevis, opponens pollicis, and abductor pollicis brevis). The sensibility of the palm remains normal because the superficial sensory branch of the median nerve branches proximal to the TCL and travels superficial to it. The role of nerve adherence is speculative.
