The cervical plexus is formed by the ventral (anterior) rami of the C1 to C5 nerve roots and innervates the diaphragm, provides motor supply to some neck muscles and cutaneous sensation to the skin of the head, neck, and chest.
- anterior rami of C1 to C5 nerves
- runs in series with the brachial plexus on scalenus medius under the prevertebral fascia and the upper part of the sternocleidomastoid
- all cutaneous branches of the cervical plexus converge and become superficial at the punctum nervosum, also known as Erb's point, at the halfway point of the posterior border of the sternocleidomastoid muscle
