Brachial plexus. The brachial plexus is a network of nerves 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.
The nerves that branch off the spinal cord in the neck exit the vertebral foramina to form an intermixing pattern called the brachial plexus. From there, the nerves go on to innervate the skin and muscles of the arm. For practical purposes, the most important nerve roots in the arm are C5, C6, and C7. It's worth knowing that about 20 percent of all cervical radiculopathies involve two or more levels.
