Brachial plexus

The brachial plexus is a group of nerves that originate from the neck region and branch off to give rise to most of the nerves that control movement in the upper limb. Injuries to the brachial plexus are common and can be debilitating. If the injury is severe it can cause weakness or paralysis of the entire upper limb.
