Description
The brachial plexus is made up of nerves from the lower cervical nerves C5-C8 and the first thoracic nerve. It supplies nerve fibers to the following areas: Chest, Shoulder, Arm, Forearm, Hand.The brachial plexus begins at the neck and crosses the upper chest to the armpit. Injuries to this network of nerves can occur when the arm is forcibly pulled or stretched.The brachial plexus is formed by the anterior primary rami of C5 through T1 and provides sensory and motor innervation of the upper extremity. The brachial plexus is divided, proximally to distally into rami/roots, trunks, divisions, cords, and terminal branches.The brachial plexus is a network of nerves in the shoulder that carries sensory and movement signals from the spinal cord to the arms and hands.
