The brachial plexus is a network of nerve fibers running from the spine formed by the ventral rami of the lower four cervical and first thoracic nerve roots (C5-C8 T1). It proceeds through the neck the axilla (armpit region) and into the arm. It is a network of nerves passing through the cervico-axillary canal to reach axilla and innervates brachium (upper arm) antebrachium (forearm) and hand.
