Right comes off brachiocephalic

Left comes off aortic arch

Terminates at Thyroid Cartilage --> Internal and External

swallowing and gag reflex

dilation/swelling on the internal carotid

baroreceptors: respond to changes in BP, mediate changes in cardiac activity

mass of tissue at bifurcation of Common carotid

Chemoreceptors:
-responds to changes in chemical composition of blood
-reflex changes in RESPIRATORY activities

-Fibrous connective tissue

-surrounds carotid artery, Internal jugular vein and vagus nerve

Spinal Nerves I, II, III

Internal Jugular vein
Internal Carotid
External carotid

Pneumonic 1, 2, 3. In in and out.

out being external... helps me remember :)

Sympathetic: speeds up heart, dilates coronary artery
                             Superior Cervical ganglion

Parasympathetic: Slows down heart, constricts coronary
                                    CN-X, Vagus Nerve

Superior Thyroid
Inferior Thyroid --- Comes off the thyrocervical trunk
Lingual
Facial
Angular
Occipital
Posterior Auricular
Maxillary (and its branches)
Superficial temporal
Ascending pharyngeal

Pneumonic
Some Idiots Laugh Frantically At Old People. Man, Someone Assist!

Opthalmic Artery which branches into:
         Supratrochlear
         Supraorbital
         Anterior Ciliary
         Lacrimal
         Posterior Ciliary
Middle Cerebral
Anterior Cerebral
Posterior Communicating

Pneumonic

Oh, Some Sand And Land Put Me At Peace

In case of occlusion, there will still be blood supply to all of the brain

Passes down the longitudinal fissurse

to medial & superior region of frontal and parietal hemispheres

Connects the 2 anterior cerebral arteries, forming a circle.

Lateral region of brain (controlling hearing, sppech and Long term memory)

Both lateral and medial parts of occipital lobe

Connects the posterior cerebral artery to the carotid arteries forming a circle.

Compromises integrity of CN III- pressing on outside of nerve

Parasympathetic Fibers affected

Occulomotor ophthalmoplegia:

Wrinkled forehead
Raised eyebrow
Ptosis
Dilated Pupil
Downward abducted eye (only lateral rectus and superior oblique functional)
