Document Summary
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 shall look at the anatomy of the fascial layers of the neck their attachments, anatomical relationships and their clinical relevance. The superficial cervical fascia lies between the dermis and the deep cervical fascia. The superficial cervical fascia blends with the paper thin" platysma muscle. The platysma is a broad superficial muscle which lies anteriorly in the neck. It has two heads, which originate from the fascia of the pectoralis major and deltoid. The fibres from the two heads cross the clavicle, and meet in the midline, fusing with the muscles of the face.
