The brachial plexus is a network of the ventral branches of the spinal nerves of the last four cervical and the first thoracic segment. The arm network is part of the peripheral nervous system. These spinal nerves unite to form three main tribes and then pass along the axillary artery in the axilla. As axillary artery the continuation of the subclavian artery in the armpit is referred. It supplies the armpit, the muscles of the shoulder and the chest and the arm.
