median nerve
The median nerve is a member of the brachial plexus. It is formed by contributions from the lateral and medial cords of the brachial plexus, primarily from spinal nerve roots C6, C7, C8, and T1.
The median nerve supplies most of the flexor muscles of the human forearm, and some hand muscles. The ulnar nerve also supplies two flexor muscles, and most of the remaining hand muscles that the median nerve does not cover.
When the median nerve is compressed, an individual's hand will feel as if it has "gone to sleep."
