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 following is a list of nerves in the human body: ... The cervical portion of the sympathetic system; ... Cervical plexus; Chorda tympani; Ciliary ganglion;
"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 ...
Afferent nerve cell bodies bring information from the body to the brain and spinal cord, while efferent nerve cell bodies bring information from the brain and spinal cord to the rest of the body. The cell bodies create long sympathetic chains that are on either side of the spinal cord. They also form para- or pre-vertebral ganglia of gross anatomy.
Branches of cervical plexus; Roots and trunks of brachial plexus; Phrenic nerve (C3,4,5) B) Vessels: Subclavian artery (Third part) Transverse cervical artery; Suprascapular artery; Terminal part of external jugular vein; C) Lymph nodes: Occipital; Supraclavicular; D) Muscles: Inferior belly of omohyoid muscle; Anterior Scalene; Middle Scalene ...
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 sympathetic trunk is a fundamental part of the sympathetic nervous system, and part of the autonomic nervous system.It allows nerve fibres to travel to spinal nerves that are superior and inferior to the one in which they originated.
