buildup of plaque,with in an artery, caused by cholestrol, calcium, clotting proteins

main "thing" that is responsible for causing blockage of the arteries

condition caused by atherosclerosis

what are the earliest reports of atherosclerosis?

what can change the onset or severity of atherosclerosis in adult as they age

blood vessels can become compromised in certain disease such as high blood pressure this can lead to vascular leasions

clot that forms on the inside of the blood vessel wall

traveling blood clot

bacteria that travels with in the vessels

can a bactermia be dangerous for medically compromised patients

cerebrovascular accident

myocardial infaarction

tissue damage

the occlusion of blood vessels caused by stroke heart attack, or gangrene is called a....

when large amounts of blood escape into the surrounding tissue without clotting

vessels that undergo localized trauma causing a "bruise" aka:

injured blood vessel allowing small amounts of blood to escape into the surrounding tissue then clotting

has there been a link between CVD and perio disease found??

one way valves that prevent backflow of blood and the spread of infection

T/F: the veins of the head and neck have no valves
True False

blood flow ____ the heart depends on gravity...there are no vavles

blood flow ____ the heart depends on the muscles and blood pressure..more valves are present

primary blood supply to the brain-goes into the brain by way of the carotid canal

supplies everything outside the brain with blood

microscopic atery

connects arteries and veins

microscopic vein

communication between vessels by the connecting channesl

extensive network of vessels

blood filled space between layers of tissues

narrowing or blockage of the arteries/vessels by plaque buildup

substances that can line the artery wall(not good)

pulse felt at the common carotid artery

the lack of valves in the head and neck is reason for....

larger, more variable, and more numerous than corresponding arteries

major suppliers to the head, neck and uupper limbs-left arise from aorta and right arise from brachiocephalic artery

inside the carotid sheath, divides into the internal and external carotid artery at the level of the larynx

swelling of common carotid artery just inferior to the bifurcation

lateral to the common carotid artery-destination is upper extermity

runs upward-no branching-supplies intracranial structures-source of opthalmic artery

supplies the extracranial structures of the head, neck, and oral cavity thorugh 4 sets of branches

4 branches of the external carotid artery

3 branches of the anteror branch (extrnal carotid)

suppplies structures inferior to the hyoid bone

supplies superior to hyoid bone-branches include dorsal, lingual,deep lingual, sublingual and suprahyoid branches

supplies face, oral buccal zygomatic nasal infraorbital and orbital regions-branches:ascending palatine, submandibular, submental, inferior labial, superior labial, and angular arteries

ascending pharyngeal artery-

2 branches of the medial branch

supplies the throat muscles

supplies the "brain wrapper"

aka:"brain wrapper"

2 branches of the posterior branch

supplies the internal eaar

supplies the suprahyoid and sternocleidomastoid muscle,scalp

divides into the superficial temporal and the maxillary artery

divides into the middle temporal - frontal branch - parietal branch-

vein that drains the brain

drains extracranial tissues

2 veins that have many anastomoses
