The median nerve provides sensation to the thumb side of the palm the thumb index middle and half of the ring finger. Nerves can be damaged by too much pressure by stretching or by a cut. Injury to the radial nerve may result in radial neuropathy also called radial nerve palsy.

The nerves of the hands are susceptible to several different types of injuries including pressure injuries stretching injuries and cutting injuries. The median nerve originates from the lateral and medial cords of the brachial plexus and has contributions from ventral roots of c5 c7 lateral cord and c8 and t1.
