Deep cervical fascia of neck

S
SupriyaDhoot

The deep cervical fascia of the neck consists of the pretracheal fascia and prevertebral fascia. The pretracheal fascia attaches superiorly to structures like the hyoid bone and inferiorly blends with the arch of the aorta. It forms the front of the carotid sheath. The prevertebral fascia attaches superiorly to the base of the skull and inferiorly splits into anterior and posterior layers. The carotid sheath is formed by the pretracheal fascia anteriorly and prevertebral fascia posteriorly. It contains the common carotid artery, internal jugular vein, and vagus nerve.

PRETRACHEAL FASCIA
ATTACHMENTS SUPERIORLY 1 Hyoid bone in the median plane 2 Oblique line of thyroid cartilage 3 Cricoid cartilage INFERIORLY Below the thyroid gland, it encloses the inferior thyroid veins, passes behind the brachiocephalic veins, and finally blends with the arch of the aorta and fibrous pericardium. ON EITHER SIDE It forms the front of the carotid sheath, and fuses with the fascia deep to the sternocleidomastoid

PREVERTEBRAL FASCIA
Attachments and Relations SUPERIORLY It is attached to the base of the skull INFERIORLY It extends into the superior mediastinum where it splits into anterior and posterior layers. Anterior layer Fascia blends with buccopharyngeal fascia and posterior layer is attached to the anterior longitudinal ligament and to the body of the fourth thoracic vertebra. ANTERIORLY It is separated from the pharynx and buccopharyngeal fascia by the retropharyngeal space containing loose areolar tissue. In the lower part of neck, prevertebral and buccopharyngeal fasciae fuse. Lymph nodes lie in the retropharyngeal space. LATERALLY It lies deep to the trapezius and is attached to fascia of sternocleidomastoid muscle.
CAROTID SHEATH
Formation: It is formed on anterior aspect by pretracheal fascia and on posterior aspect by prevertebral fascia. Contents: The contents are the common or internal carotid arteries, internal jugular vein and the vagus nerve. It is thin over the vein. In the upper part of sheath, there are IX, XI, XII nerves also. These nerves pierce the sheet at different points. Relations: 1. The Ansa cervicalis lies embedded in the anterior wall of the carotid sheath. plastered to the prevertebral fascia. the sternocleidomastoid, and is fused to the layers 2. The cervical sympathetic chain lies behind the sheath, 3. The sheath is overlapped by the anterior border of the deep cervical fascia.
