1

organs located in the neck

larynx, pharynx, thyroid, and parathyroid glands

2

skeleton of neck is formed by:

cervical vertebrae, hyoid bone, manubrium of the sternum, and clavicles

3

hyoid bones lie in the ______ part of neck at the level of _______

anterior, C# vertebra

4

structures in the neck are surrounded by ________ and are divided into different partitions by layers of ____________

superficial fascia, deep cervical fascia

5

thin layer of CT that lies between the dermis of the skin and the investing layer of deep cervical fascia

superficial cervical fascia

6

contains cutaneous nerves, blood, and lymphatic vessels, superficial lymph nodes, and variable amounts of fat;

superficial cervical fascia

7

anterolaterally, the deep cervical fascia contains the

platysma

8

muscle of facial expression

platysma

9

superior attachment of platysma

inferior border of mandible, skin, and subcutaneous tissues of lower face

10

inferior attachment of platysma

fascia covering superior parts of pectoralis major and deltoid muscles

11

innervation of platysma

cervical branch of fascial nerve (CN VII)

12

action of platysma

draws corners of mouth inferiorly and widens it; draws skin of neck superiorly when teeth are clenched indicating tension

13

contains 3 layers; investing, pretracheal, and prevertebral

deep cervical fascia

14

functions of the 3 layers of Deep cervical fascia

support the viscera, muscles, vessels, and deep lymph nodes

15

Provide the slipperiness that allows structures in the neck to move and pass over one another without difficulty;

layers of deep cervical fascia

16

form natural cleavage planes, allowing separation of tissues during surgery

deep cervical fascia layers

17

superficial layer of deep fascia, surrounding the entire neck deep to subcutaneous tissue

investing layer

18

splits to enclose the SCM and trap muscle; and the parotid and submandibular glands

investing layer

19

superior attachment of investing layer

superior nuchal line of occipital bone, mastoid processes of the temporal bones, zygomatic arches, inf border of mandible, hyoid, and SP of the cervical vertebrae

20

inf attachment of investing layer

manubrium of sternum, clavicles, acromions, and spines of scapulae

21

post border of investing layer

continuous with C7 SP and the nuchal ligament

22

lies between the two layers of investing fascia that enclose the SCM, one layer attaches to the ant and the other post surface of the manubrium,

suprasternal space of investing layer

23

suprasternal space consists of

anterior jugular veins, jugular venous arch, fat, and a few deep lymph nodes

24

layer limited to the anterior part of the neck

pretracheal layer

25

extends inferiorly from the hyoid into the thorax, where it blends with the fibrous pericardium covering the heart

pretracheal layer

26

includes a thin muscular part, which encloses the infrahyoid muscles

pretracheal layer

27

includes a visceral part, which encloses the thyroid gland, trachea, and esophagus

pretracheal layer

28

Is continuous post-sup with the buccopharyngeal fascia

pretracheal layer

29

the pretracheal layer blends laterally with

the carotid sheaths

30

tubular fascial investment that extends from the cranial base to the root of the neck

carotid sheath
