Wikipedia
The median nerve is a nerve in humans and other animals in the upper limb. It is one of the five main nerves originating from the brachial plexus.
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 & T1 (medial cord).
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.
Usage examples of "median nerve".
Twice I found an arm exposed and worked my thumb into the median nerve with force enough to produce great pain but there was no sound, no jerking to free the arm, and after a time I realised that we were locked together, these two men and I, across the body of the Cuban.
So it had to be the rear tyre, and as he leaned out of the car to look at it he kept the gun trained on me and the nearest part of his body was his gun-hand and I had something like two seconds while he looked at the tyre and I used enough force to paralyse the arm through the median nerve and deaden the trigger-finger because if I'd used more it would have caused a great deal of pain and I didn't want him vomiting, I can't stand that.
