7

neck layers are compartmentalized by what two layers

cervicle fascia: deep and superficial

8

Where does the superficial cervicle fascia layer lie?

btwn dermis of skin and investing layer of deep cervicle fascia

9

Where does the playtsma muscle lay?

superficial layer of superficial cervicle fascia

10

What are the three layers of the deep superficial fascia?

superficial (investing)
Pretracheal
Prevertebral

11

What layer invests the trapezius and SCM?

The superficial part of the Deep cervicle fascia

12

Where is the pretracheal layer of deep cervicle fascia limited to?

Anterior part of neck

13

What are the two divisions of the pretracheal layer?

Visceral and musclular

14

What does the muscular layer of the pretracheal layer contain?

infrahyoid muscles

15

What does the visceral layer of the pretracheal layer contain?

thyroid gland trachea and esophagus

16

What layer is the visceral layer of pretracheal fascia continuous with

buccopharyngeal

17

thin, posterior lamina of the pretracheal fascia, seperates eso from prevertebral fascia

buccopharyngeal fascia

18

What nerve lies btween visceral and pretracheal fascia?

recurrent laryngeal

What contributes to the posterior portion of the carotid sheath

prevertebral fascia

20

What is the anterior lamina called?

21

Contents of carotid sheath

Common and internal carotid arteries
the IJV
The vagus nerve

22

What makes up the carotid sheath

fascial sheath blends anteriorly with investing and pretracheal layers of fascia and posterioly with prevertebral layer of deep cervicle fascia

23

What blends with the percardium on the heart?

pretracheal fascia
