Fascia is an internal connective tissue which forms bands or sheets that surround and support muscles, vessels and nerves in the body. In the neck, these layers of fascia not only act to support internal structures, but also help to compartmentalise structures of the neck. There are two fascias in the neck – the superficial cervical fascia and the deep cervical fascia. In this article, we ...
The deep cervical fascia (or fascia colli in older texts) lies under cover of the platysma, and invests the muscles of the neck; it also forms sheaths for the carotid vessels, and for the structures situated in front of the vertebral column. Its attachment to the hyoid bone prevents the formation of a dewlap. [1] The investing portion of the fascia is attached behind to the ligamentum nuchæ ...
Investing layer This layer of the deep cervical fascia is a collar of fascia surrounding the whole neck and contains the trapezius and sternocleidomastoid muscles. The investing layer is comparable to deep fascias of other regions of the body. It is the most superficia l deep fascial layer. At the four midpoints (anterior, posterior and two lateral) of the neck, this investing layer splits ...
The deep fascia of the neck lies deep to the superficial cervical fascia, a layer that is integral to the subcutaneous tissue and invests the platysma muscle. The deep fasciae of the neck are anatomic structures with crucial clinical significance for both surgical procedures and in the spread of infection and neoplasia.
Deep cervical fascia The deep cervical fascia is located under the skin, the superficial fascia, and the platysma muscle. It is a thin lamina that envelops the neck region like a collar. At the upper side, the fascia inserts on the periostium of the occipital external protuberance, the mastoid process of the temporalis bone, the external acoustic meatus, the inferior border of the zygomatic ...
