Anatomy Location Function Injury and FAQs Biology Diagrams The plexus is formed by the anterior rami (divisions) of cervical spinal nerves C5, C6, C7 and C8, and the first thoracic spinal nerve, T1. In this article, we shall look at the anatomy of the brachial plexus - its formation and anatomical course through the body.
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.
Brachial Plexus Anatomy Biology Diagrams
The brachial plexus is a network of nerves that gives rise to all the motor and sensory nerves of the upper extremity. This plexus arises from the anterior rami of spinal nerves C5-T1 that undergo several mergers and splits into trunks and divisions, until they finally give rise to their terminal branches.

The brachial plexus is a network of nerves that supply the upper extremities. Learn about its anatomy, branches, functions, and related conditions. The brachial plexus is a complex network of nerves that originates in the neck and provides motor and sensory innervation to the upper limb, including the shoulder, arm, forearm, and hand. Its formation involves the lower four cervical nerves (C5-C8) and the first thoracic nerve (T1), with occasional contributions from C4 or T2. Structure Roots: The nerves form midline cords that branch into smaller branches to supply motor and sensory innervation to the chest, shoulder, arm and hand. The brachial plexus is a bundle of nerves at the base of the neck that forms three main divisions to supply motor innervation to parts of the chest, shoulder and arm. These three cords include several spinal segments (C4-8) as well as one thoracic
