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 ...
Roof: Investing layer of the deep cervical fascia. Floor: (From superior to inferior) 1) M. semispinalis capitis 2) M. splenius capitis 3) M. levator scapulae 4) M. scalenus posterior 5) M. scalenus medius
The nerves descend in the posterior triangle of the neck beneath the platysma muscle and the deep cervical fascia. [citation needed] Near the clavicle, the supraclavicular nerves perforate the fascia and the platysma muscle to become cutaneous. They are arranged, according to their position, into three groups—anterior, middle, and posterior.
The carotid sheath is a condensation of the deep cervical fascia [1]: 578 enveloping multiple vital neurovascular structures of the neck, [2] including the common and internal carotid arteries, the internal jugular vein, the vagus nerve (CN X), and ansa cervicalis. [1]: 578 [2] The carotid sheath helps protects the structures contained therein. [2]
It is separated from the sternocleidomastoid muscle by the investing layer of the deep cervical fascia, and is covered by the platysma, the superficial fascia, and the integument; it crosses the cutaneous cervical nerve, and its upper half runs parallel with the great auricular nerve.
The alar fascia is a portion of the deep cervical fascia. Divisions ... the lower portions of the anterior jugular veins and their transverse connecting branch, ...
The superficial cervical fascia is a thin layer of subcutaneous connective tissue that lies between the dermis of the skin and the deep cervical fascia. [1] It contains the platysma , cutaneous nerves [ 1 ] [ 2 ] from the cervical plexus , [ 2 ] blood vessels, and lymphatic vessels.
The investing layer of deep cervical fascia is the most superficial part of the deep cervical fascia, and encloses the whole neck. It is considered by some sources to be incomplete [ 1 ] or nonexistent.
