Brachial plexus

Watch videos

The brachial plexus is a network of nerves located in the neck region, between the anterior and middle scalene muscles. It passes through the axilla and courses through the arm to innervate the muscles, joints and skin of the upper limb. According to its anatomical position, the brachial plexus is divided into two main parts: supraclavicular and infraclavicular. The supraclavicular part (rami and trunks with their branches) of the brachial plexus is located in the posterior triangle of the neck, while its infraclavicular part (cords and their branches) is in the axilla. The brachial plexus gives off lateral branches (anterior and posterior) and five major terminal branches.
