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 right brachial plexus with its short branches, viewed from in front. The Sternomastoid and Trapezius muscles have been completely, the Omohyoid and Subclavius have been partially, removed; a piece has been sawed out of the clavicle; the Pectoralis muscles have been incised and reflected.

The medial cord is the part of the brachial plexus formed by of the anterior division of the lower trunk (C8-T1). [1] Its name comes from it being medial to the axillary artery as it passes through the axilla. The other cords of the brachial plexus are the posterior cord and lateral cord.
This plexus lies within the psoas major muscle. Nervi of the plexus serve the skin and the muscles of the lower abdominal wall, the thigh and external genitals. The largest nerve of the plexus is the femoral nerve. It supplies anterior muscles of the thigh and a part of skin distal to the inguinal ligament.
English: The branchial plexus, including all branches of the C5-T1 ventral primary rami. Includes mnemonics for learning the plexus' connections and branches. An original illustration by Chris Talbot, M.S. in Anatomy and student instructor at Case Western Reserve University.
The subclavian nerve, also known as the nerve to the subclavius, is a small branch of the upper trunk of the brachial plexus. It contains axons from C5 and C6 . It innervates the subclavius muscle .
