Document Summary

The cervical plexus is a network of nerve fibres that supplies innervation to some of the structures in the neck and trunk. It is located in the posterior triangle of the neck, halfway up the sternocleidomastoid muscle, and within the prevertebral layer of cervical fascia. The plexus is formed by the anterior rami (divisions) of cervical spinal nerves c1-c4. In this article, we shall look at the anatomy of the cervical plexus its branches, functions and clinical correlations. The spinal nerves c1 c4 form the basis of the cervical plexus. At each vertebral level, paired spinal nerves leave the spinal cord via the intervertebral foramina of the vertebral column. Each nerve then divides into anterior and posterior nerve fibres. The cervical plexus begins as the anterior fibres of the spinal nerves c1, c2, c3 and c4. These fibres combine with each other to form the branches of the cervical plexus.
