DEEP FASCIA

PREVERTEBRAL FASCIA
-anterior to verte. fascia...
3. Anterior to the vertebral column, the prevertebral fascia splits into two
layers separated by loose connective tissue; the anterior layer or alar fascia ends inferiorly by fusing with the posterior wall of the esophagus
at about vertebral level T3 and the posterior layer continues inferiorly
on the anterior surface of thoracic vertebral bodies
DEEP FASCIA

PREVERTEBRAL FASCIA
-clinical note: "danger space"
4. Clinical note: a "danger space" exists between the two layers of the
prevertebral fascia that lie anterior to the vertebral column; an infec-
tion within this space can spread essentially unimpeded between the base of the skull
and thorax.
DEEP FASCIA

PRETRACHEAL FASCIA
D. Pretracheal Fascia: ensheaths the larynx, trachea, and thyroid gland.
DEEP FASCIA

CAROTID SHEATHS
E. Carotid Sheaths; lie deep to the sternocleidomastoids and extend from the
base ofthe skull to the root ofthe neck; each contains an internal jugular
vein, common/internal carotid artery, vagus nerve, some deep cervical lymph nodes, and the inferior root of an ansa cervicalis
DEEP FASCIA

CLINICAL NOTE
