The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.

The brachial plexus is formed by the ventral rami of C5-C8-T1 spinal nerves, and lower and upper halves of C4 and T2 spinal nerves. The plexus extends toward the armpit. The ventral rami of C5 and C6 form upper trunk, the ventral ramus of C7 forms the middle trunk, and the ventral rami of C8 and T1 join to form the lower trunk of the brachial ...

The subclavian nerve is a branch of the upper trunk of the brachial plexus. It contains axons derived from the ventral rami of the C5 and C6 cervical spinal nerves. [1] The origin is situated within the posterior triangle of the neck. [2]

The musculocutaneous nerve is a mixed branch of the lateral cord of the brachial plexus derived from cervical spinal nerves C5-C7. It arises opposite the lower border of the pectoralis minor . [ 1 ] It provides motor innervation to the muscles of the anterior compartment of the arm : the coracobrachialis , biceps brachii , and brachialis . [ 2 ]
