Cervical fascia
The cervical fascia ( lat. Fascia cervicalis , also Fascia colli ) is a fascia that consists of three leaves, a superficial, middle and deep leaf. These each cover different parts of the neck .
Lamina superficialis
The superficial sheet of the cervical fascia, the superficial lamina, lies behind the platysma , envelops the Mm. sternocleidomastoidei and continues dorsally to encircle the entire neck. In the neck, above the trapezius muscle , it merges into the nuchal fascia .
Lamina praetrachealis
The middle sheet of the cervical fascia, the praetracheal lamina, encompasses the infrahyric muscles and extends from the hyoid bone to the sternum and collarbone . It is fused with the vagina carotica (vascular nerve sheath), which contains the internal jugular vein . By the train of Mm. omohyoidei can thus be prevented from collapsing at low blood pressure values.
Lamina prevertebralis
The deep sheet of the cervical fascia, the lamina prevertebralis, directly surrounds the autochthonous muscles of the neck and the cervical spine further inside . It extends from the base of the skull to the third thoracic vertebra and merges there into the endothoracic fascia . The prevertebral lamina includes the cervical plexus , which breaks through the superficial lamina at the hereditary point ( punctum nervosum ). In front of the prevertebral lamina is the peripharyngeal space , which merges caudally into the mediastinum . Inflammatory processes of the throat can descend into this, as there is no demarcation between the two spaces.
