They help to contain the spread of disease and form natural planes of cleavage during surgery

Front 21

Where is the superficial cerivcal fascia and what does it contain?

Back 21

where: between dermis and deep fascis
contains: cutaneous nn, blood, lymphatic vessels, superficial lymph nodes, and inferolaterally the platysma m.

Front 22

name 3 layers of deep cervical fascia

Back 22

Investing fascia
Visceral fascia
Pre-vertebral fascia

Front 23

Describe the investing layer of deep cervical fascia

what does it cover?

Back 23

circles the neck and envelopes the scm and trapezious mm; covers the parotid and submandibular glands, massester and temporalis mm. superiorly; the stylomandibular lig is a modification of this layer; inferiorly goes all the way to the sternum and creates the suprasternal space (contains the inferior ends of the anterior jugular vv, fat, and deep lymph nodes)

Front 24

what are the 2 divisions of the visceral fascia layer of the deep cervical fascia?

what muscles and viscera are covered by the layer?

Back 24

Pretracheal: lies anteriorly in front of trachea and covers thyroid
Buccopharyngeal- lies posteriorly and covers posterior wall of pharynx
Superior extent: the hyoid bone
Inferior extent: fibrous pericardium around great vessels
Contains: thyroid, trachea, esophagus, larynx, and pharynx

Front 25

describe the prevertebral layer of deep cervical fascia.

contents, extent, etc

Back 25

Surrounds: deep mm. of neck, spinal nn, and vertebrae
Extends from base of skull to T3 vertebrae where it fuses with the anterior longitudinal ligament
Laterally extend to form an axillary sheath, which surrounds axillary vessels and brachial plexus
**superior portion of sympatheric trunks are embedded here**
