Colles' fascia emerges from the perineal membrane, which divides the base of the penis from the prostate. Colles' fascia emerges from the inferior side of the perineal membrane and continues along the ventral (inferior) penis without covering the scrotum. It separates the skin and subcutaneous fat from the superficial perineal pouch.
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]
Horizontal extent - From ligamentum nuchae when traced forward, the fascia splits and encloses trapezius, reunites and form roof of posterior triangle of neck; again splits and encloses sternocleidomastoid, reunites and forms the roof of anterior triangle.
The cervical fascia is fascia found in the region of the neck. It usually refers to the deep cervical fascia. However, ...
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 prevertebral fascia is fixed above to the base of the skull, and below it extends behind the esophagus into the posterior mediastinal cavity of the thorax. It descends in front of the longus colli muscles. The prevertebral fascia is prolonged downward and laterally behind the carotid vessels and in front of the scalene muscles.
The retropharyngeal space (abbreviated as "RPS" [1] [2]) is a potential space [2] [3] and deep compartment of the head and neck [1] situated posterior to the pharynx. [4] The RPS is bounded anteriorly by the buccopharyngeal fascia, posteriorly by the alar fascia, and laterally by the carotid sheath.
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.
