It is located in the neck, deep to the sternocleidomastoid muscle. [5] The branches of the cervical plexus emerge from the posterior triangle at the nerve point, a point which lies midway on the posterior border of the sternocleidomastoid.
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 location of the muscle in a standard human body. The location first specifies a group such as head, neck, torso, upper limbs, or lower limbs, then may have more specific information. However this additional information must be describing location not function. Origin The bone or other structure the muscle is attached to that remains ...

Posteriorly: Anterior border of the trapezius. Inferiorly: Middle one third of the clavicle. Roof: Investing layer of the deep cervical fascia. Floor: (From superior to ...

The top section of the spine is the cervical section, which contains nerves that innervate muscles of the head, neck and thoracic cavity, as well as transmit sensory information to the CNS. The cervical spine section contains seven vertebrae, C-1 through C-7, and eight nerve pairs, C-1 through C-8.
The transverse cervical nerve (superficial cervical or cutaneous cervical) is a cutaneous (sensory) nerve of the cervical plexus that arises from the second and third cervical spinal nerves (C2-C3). It curves around the posterior border of the sternocleidomastoideus muscle, then pierces the fascia of the neck before dividing into two branches ...
"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 ...
