The cervical plexus is situated deep to the sternocleidomastoid muscle, internal jugular vein, and deep cervical fascia. [1] It is situated anterior to the middle scalene muscle, and levator scapulae muscle. [1]
"Erb's point" is also a term used in head and neck surgery to describe the point on the posterior border of the sternocleidomastoid muscle, approximately 2-3cm above the clavicle, overlying the transverse process of the sixth cervical vertebra, [3] where the four superficial branches of the cervical plexus—the greater auricular, lesser ...
Cervical plexus. The cervical plexus is formed by the ventral rami of the upper four cervical nerves and the upper part of fifth cervical ventral ramus. The network of rami is located deep to the sternocleidomastoid within the neck. The cervical plexus innervates muscles of the neck and areas of skin on the head, neck and chest.
The lateral branch often joins that of the second cervical. The posterior division of the suboccipital, and the medial branches of the posterior division of the second and third cervical nerves are sometimes joined by communicating loops to form the posterior cervical plexus.

The supraclavicular nerve is a cutaneous (sensory) nerve of the cervical plexus that arises from the third and fourth cervical (spinal) nerves. It emerges from beneath the posterior border of the sternocleidomastoid muscle, then split into multiple branches. Together, these innervate the skin over the shoulder.
Hypoglossal nerve, cervical plexus, and their branches. ... The nerve is regarded as arising evolutionarily from nerves of the cervical spine, [2] ...
The great auricular nerve is a cutaneous (sensory) nerve of the head. It originates from the second and third cervical (spinal) nerves (C2-C3) of the cervical plexus.It provides sensory innervation to the skin over the parotid gland and the mastoid process, parts of the outer ear, and to the parotid gland and its fascia.
