2023年10月12日 · 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.

2023年6月15日 · The cervical plexus is a conglomeration of cervical nerves formed by the anterior (ventral) rami of spinal nerves C1-C4 (a.k.a. 1st-4th cervical nerves). These are the roots (limbs) of the cervical plexus.

The cervical plexus is a nerve plexus of the anterior rami of the first (i.e. upper-most) four cervical spinal nerves C1-C4. [1] [2] [3] [4] The cervical plexus provides motor innervation to some muscles of the neck, and the diaphragm; it provides sensory innervation to parts of the head, neck, and chest. [1]

The superficial branches are the great auricular nerve, lesser occipital nerve, transverse cervical, suprasternal, and supraclavicular nerves. The deep branches are the phrenic, communicantes cervicalis, communicating, and muscular.

2025年1月21日 · Cervical levels C 1 –C 4 are the main contributors to the group of nerves called the cervical plexus; in addition, small branches of the plexus link C 1 and C 2 with the vagus nerve, C 1 and C 2 with the hypoglossal nerve, and C 2 –C 4 with the accessory nerve.

The cervical plexus is a network of nerves which forms from the anterior rami of C1-C4 within the prevertebral fascia in the posterior triangle of the neck. Its branches can loosely be described as sensory of motor components.

2025年1月20日 · The cervical plexus is a network of nerves formed by the anterior rami of the upper four cervical spinal nerves (C1–C4). It is located deep in the neck, on the lateral side of the upper cervical vertebrae.

2023年8月19日 · The first (i.e., uppermost) four cervical spinal nerves C1–C4 form the anterior rami of the nerve plexus known as the cervical plexus. The cervical plexus provides motor awareness to give sensory innervation to parts of the head, neck, and chest.

The great auricular nerve originates from the cervical plexus and is composed of branches from spinal nerves C2 and C3. It provides sensory innervation for the skin over the parotid gland and mastoid process, and both surfaces of the outer ear.

o A nerve plexus is a network of interwoven nerves. o Cervical plexus provides nerves to: •Head. •Neck and •Shoulder. •Supplies skin and muscles of neck and thoraco-abdominal diaphragm.
