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.
Brachial plexus (figs. 8-1, 8-7, 8-8 and 8-9) The nerves to the upper limb arise from the brachial plexus, which is situated partly in the neck and partly in the axilla. It is formed by the union of the ventral rami of the lower four cervical and first thoracic nerves (C5,6,7,8; T1). Frequently it receives a contribution from one nerve higher or one nerve lower.
