Anatomy and Physiology of Neck Flashcards
boundaries of the anterior triangle
Anterior: midline of the neck
Posterior: anterior border of sternocleidomastoid
boundaries of posterior triangle
-Anterior: posterior border of sternocleidomastoid
-Posterior: anterior border of trapezius
contents of anterior triangle arteries, veins, nerves, lymph
Common carotid (+ ext and int)
facial artery
IJV
Facial vein
9,10,11,12
Laryngeal branch of 10
Submandibular nodes
Submental nodes
(main artery and vein- carotid and IJV
last 4 nerves and main branch of X
anterior so lymph from front of face)
contents of posterior triangle arteries, veins, nerves, lymph
Occipital artery
External jugular vein
Accessory nerve
Cervical nerve plexus
Lymph nodes
**occipital as at the back
EJV as its left over from IJV in ant
accesory nerve as that supplies 2 muscles in back of neck
what level does the common carotid devide at
C4
what is the only artery with branches in the neck
external carotid
where do the lymph in the neck drain to
first then last
cisterna chyli- think a cold cistern of lymph
thoracic duct of left
what nodes drain the scalp
occipital
cause of lymphadenopathy x3
IIM
INFECTIVE
INFLAMMATORY
MALIGNANT
what other substance does the thyroid gland produce
and what does it do
calcitonin
lower calcium and raise phosphate
4 different types of thyroid cancer
Papillary
Follicular
Medullary
Anaplastic
causes of the different types of thyroid cancer: papillary
lymph metastasis
causes of the different types of thyroid cancer: follicular
haematogenous metastasis
causes of the different types of thyroid cancer: medullary
familial association
10% parafollicular C cells
“medulla- me motha”
causes of the different types of thyroid cancer: anaplastic
age type
prognosis
local spread
very old
poor prognosis
think hard, old plastic- would be very bad to have it in the thyroid so poor prognosis, and can’t move very easily so is only from local spread
