what is the root of the neck

the junction between thorax and the neck

what is another name for the root of the neck

thoracocervical region

1st rib
manubrium
T1 v. body

what are the arteries of the root of the neck

the ABC’s

brachiocephalic trunk on right side
subclavain artery on left side

Loook in the book

What are the viens of the root of the neck

- EJV - AJV - IJV - subclavian

what are the nerves of the root of the neck

- vagus - phrenic - sympathetic trunks

How does the vagus n enter the thorax in the root of the neck

from the right side it enter the thorax anterior to the 1st part of the subclavian a from the left it enters the thorax between left common caroitd and left subclavian

what is the recurrent laryngeal n and how does it enter the thorax in the root of the neck

this is the branch of the vagus that goes to the larynx to supply motor and sensory Right- loops aroudn sublavian T1-T2 level Left- loops around arch of aorta T4-T5 level

how does the phrenic n enter the thorax of the root of the neck

anterior to anterior scalenes and enters thorax between subclavian aa and vv

What is in the sympathetic trunk from the root of the neck

there is superior, middle and inferior ganglia in the cervical region S- head, neck, heart M- neck, heart I- neck, heart, arm

Ganglia of spinal nerves

via gray rami communicantes

ganglia of thoracic visera

via cardiopulmonary splanchnic nerves

ganglia of head and viscera of the neck

via cephalic arterial branches

What does the thoracic duct do

collect most of the lymph in the body except what is collected by the right lymphatic duct - it will drain into the left sublavian v and the left inernal jugular v

what is the right lymphatic duct

this contains the right arm and the right side of the chest, neck and head and lower left lobe of the lungs

is there lymph in the spinal cord?

there is a new study the found fx lymph vessel lining the dural sinuses. they look like the lymp and connect to the deep cervical lymph nodes

What feeds into the Facial V

Angular v

What branch is the Accessory phrenic n from

it is from the branch of subclavius nerve IT passes downward to the phrenic nerve down from the C5 spinal n. from the subclavius nerve through the subclavian v. to join the phrenic n.

what does the lingual a supply to

tongue, suprahyoid muscles, palatine tonsil

what does the lingual a branch off from

what does the occipital a supply to

lateral neck, posterior neck, posterior scalp

what does the occipital a branch off from

``` Sternocleidomastoid brs. Auricular br. Mastoid br Descending br Occipital brs ```

what does the posterior auricular a supply too

part of the external ear, scalp and deeper structures posterior to the ear

what does the posterior auricular a branch off from

Auricular br. Occipital br. Stylomastoid br.

what does the superficial temporal a suppy too

scalp of the lateral ride o the head; lateral face; temporalis m.

what does the superficial temporal a branch off from

``` Transverse facial a. Anterior auricular brs Zygomaticoorbital a. Middle temporal a. Frontal br. Parietal br. ```

what does the superior thyroid a supply to

throid gland, upper part of the larynx, infrahyoid mm, SCM m.

what does the superior thyroid a branch off from

``` Infrahyoid br. Sternocleidomastoid br. Superior laryngeal a. Criothyroid br. Glandular brs. ```
