3. Pretracheal Fascia

Front 4

Investing Fascia

Back 4

-Completely surrounds the neck and encloses the trapezius and sternocleidomastoid muscles
-It is pierced by the anterior and external jugular veins and by cutanous nerves from the cervical plexus

Front 5

Prevertebral Fascia

Back 5

-Surroudsn the vertebral column and associated muscles

Front 6

Pretracheal fascia

Back 6

-A collection of fascias that surround the trachea, esophogus and thryoid gland
-Anteriorly, it separates the infrahyoid muscles for the deeper trachea an thyroid gland
-Posteriorly, the buccopharyngel fascia separates the pharyns and esophogus from the prevertebral layer
-Extends interiorly into the thorax

Front 7

Carotid Sheath
