The pretracheal layer of the deep cervical fascia passes in front of the carotid sheath (i.e., common carotid artery, internal jugular vein, and vagus nerve) and in front of the cervical viscera (larynx, oesophagus, and pharynx). The muscular layer ensheathes the infrahyoid muscles. Above, the pretracheal fascia is fixed to the hyoid bone.
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]
The buccopharyngeal fascia is a thin lamina given off from the pretracheal fascia. [citation needed] It is the portion of the pretracheal fascia situated posterior and lateral to the pharynx. It encloses the entire superior part of the alimentary canal. [3] The buccopharyngeal fascia envelops the superior pharyngeal constrictor muscles.
A fascial compartment is a section within the body that contains muscles and nerves and is surrounded by fascia. In the human body , the limbs can each be divided into two segments: The upper limb can be divided into the arm and the forearm and the sectional compartments of both of these – the fascial compartments of the arm and the fascial ...
Fascial spaces (also termed fascial tissue spaces [1] or tissue spaces [2]) are potential spaces that exist between the fasciae and underlying organs and other tissues. [3] In health, these spaces do not exist; they are only created by pathology, e.g. the spread of pus or cellulitis in an infection.
Superiorly, the retropharyngeal space terminates at the base of the skull (more specifically, at the clivus [2]). [1] [5] Inferiorly, the true RPS terminates at a variable level along the upper thoracic spine with the fusion of alar fascia and visceral fascia; [1] sources either give the inferior termination of the true RPS as occurring at approximately the vertebral level of T4 [2] or at a ...

The septa are formed from the fascia which is made up of a strong type of connective tissue. The fascia also separates the skeletal muscles from the subcutaneous tissue. [2] Due to the great pressure placed on the leg, from the column of blood from the heart to the feet, the fascia is very thick in order to support the leg muscles. [3]
