Deep cervical fascia of neck .. it contains self notes from BDC anatomy ......

1. DEEP CERVICAL
FASCIA OF NECK

9. PRETRACHEAL
FASCIA

10. 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

12. PREVERTEBRAL
FASCIA

13. 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.

14. CAROTID
SHEATH

15. 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.
