Anatomical terms of neuroanatomy

The median nerve originates from the lateral and medial cords of the brachial plexus,[1] and has contributions from ventral roots of C5-C7 (lateral cord) and C8 and T1 (medial cord).[1][2]

The median nerve is the only nerve that passes through the carpal tunnel. Carpal tunnel syndrome is the disability that results from the median nerve being pressed in the carpal tunnel.
