The five "branches" of the brachial plexus, which supply the arm and shoulder, make up the fifth and final level. The musculocutaneous, axillary, radial, median, and ulnar nerves are the names of these five branches.
The skin and musculature of the upper limb are supplied by a network of nerve fibers known as the brachial plexus. It starts in the neck's base, travels through the axilla, and continues all the way down the upper extremities. The first thoracic spinal neuron, T1, and the anterior rami (divisions) of cervical spinal nerves C5, C6, C7, and C8 together make up the plexus. The genesis and anatomical course of the brachial plexus through the body will be discussed in this article.
Five sections make up the brachial plexus axillary: the roots, trunks, divisions, cords, and branches . These divisions serve just to explain the brachial plexus and have no functional distinctions.
