Common causes of carotid artery disease are atherosclerosis, which is a gradual build up of plaque, which restricts blood flow. Plaques consist of calcium, cholesterol, etc.

Which pulse pressure point has the greatest amplitude and why?
The common carotid artery - because it's closest to the heart.
What is the vertebral level of the bifurcation of the common carotid artery?
The bifurcation (splitting) of the common carotid artery is in line with/at the level of the intervertebral disc between the third and fourth cervical vertebral (between C3 and C4).
What it the pathway of blood from heart to anterior cerebral artery?
L ventricleAscending aortaAortic ArchBrachiocephalic trunkR Common Carotid arteryR Internal Carotid arteryR anterior cerebral artery
How do I trace blood from the ascending aorta to the lower right first molar?
The first thing is to determine what artery provides blood to the lower right first molar. The lower teeth sit in the mandible and are supplied by branches of the The major artery in the mandible supplying the teeth is the inferior alveolar artery, which sends branches to supply the roots of each tooth (including the first molar) in the lower jaw. Next is to find the origin of the inferior alveolar artery and work backwards until we get to the ascending aorta. The inferior alveolar artery is a branch of the internal maxillary artery, which itself is a branch of the external carotid artery. The external carotid artery is a branch of the common carotid artery. So far everything has been symmetrical, so it hasn't mattered whether we specified that the artery was on the right or the left side. But the common carotid arteries behave a little differently. The right common carotid is a branch of the innominate artery, which branches from the aortic arch. The left common carotid artery branches directly from the aortic arch. Since we're concerned with the lower right first molar, we'll work backwards from the right common carotid, innominate artery, and aortic arch. The last bit is just to know that the aortic arch is an extension of the ascending aorta. With that, we're done. Now we just sew the whole thing together, artery by artery, in the reverse order: Ascending aorta -> aortic arch -> innominate artery -> right common carotid artery -> right external carotid artery -> right internal maxillary artery -> right inferior alveolar artery -> branch to lower right first molar.
What is the main blood vessel that goes to the brain?
Carotid arteries supply blood to brain . Blood is supplied to the entire brain by 2 pairs of arteries: the internal carotid arteries and vertebral arteries. The right and left vertebral arteries come together at the base of the brain to form a single basilar artery. The basilar artery joins the blood supply of the internal carotid arteries in a ring at the base of the brain. This ring of arteries is called the circle of Willis. The circle of Willis provides a safety mechanism...if one of the arteries gets blocked, the "circle" will still provide the brain with blood.
Compare origins of the carotid arteries of a human to those of a cat?
In the human, the right common carotid artery branches from the brachiocephalic artery, whereas the left common carotid artery comes directly from the aortic arch. In the cat, both common carotid arteries branch from the brachiocephalic artery.
What are the three blood vessels that exit from the aortic arch?
Brachiocephalic trunk Left common carotid artery Left subclavian artery
What examinations may be performed to identify a lesion of the common carotid artery?
what examinations may ne performed to identify a lesion of the common carotid artery
What are the two pairs of arteries arising from the internal carotid artery?
1) maxillary artery 2) superficial temporal artery
Is the Common carotid artery external or internal?
internal
Gives rise to the right common carotid and right subclavian artery?
brachiocephalic artery
Which pulse pressure point has the greatest amplitude and why?
The common carotid artery - because it's closest to the heart.
What artery branches off left brachiocephalic artery?
The brachiocephalic artery divides into the right common carotid artery and the right subclavian artery.
Two arteries are formed by the division of the brachipcephalic artery?
The brachiocephalic artery divides into the right common carotid artery and the right subclavian artery.
What does the left and right common carotid arteries branch into?
Right- Brachiocephalic artery Left- subclavian artery
