	Anterior cerebral artery - Wikipedia, the free encyclopedia
		The arterial circle and arteries of the brain.
		The anterior cerebral arteries (top of figure) arise from the trifurcations of the internal carotid arteries into the anterior cerebral artery, middle cerebral artery and posterior communicating artery on each side.
		It arises from the internal carotid artery and is part of the Circle of Willis.

	Middle cerebral artery - Wikipedia, the free encyclopedia
		The middle cerebral arteries (top of figure) arise from the internal carotid arteries.
		The middle cerebral artery (MCA) is one of the three major paired arteries that supplies blood to the brain.
		The MCAs rise from trifurcations of the internal carotid arteries and thus are connected to the anterior cerebral arteries and the posterior communicating arteries, which connect to the posterior cerebral arteries.

	Anterior Cerebral Artery
		Perforating branches (including the recurrent artery of Heubner and Medial Lenticulostriate Arteries) supply the anterior limb of the internal capsule, the inferior portions of head of the caudate and anterior globus pallidus.
		Infarction of anterior corpus callosum and basal ganglia structures (caudate, globus pallidus).
		Continuation of the Anterior Cerebral Artery as it arches superiorly and posteriorly.

	Cerebral Circulation Information on Healthline
		The basilar artery branches into the anterior inferior cerebellar artery, the superior cerebellar artery, the posterior cerebral artery, the potine arteries (that enter the pons), and the labyrinthine artery that supplies the internal ear.
		The basilar artery (formed by the fusion of the vertebral arteries) divides into left and right posterior cerebral arteries that are connected (anastomsed) to the corresponding left or right internal carotid artery via the respective left or right posterior communicating artery.
		The cerebral arteries provide blood to the brain, but a sufficient arterial blood pressure is required to provide an adequate supply of blood to all brain tissue.

	eMedicine - Anterior Circulation Stroke : Article Excerpt by: Alison Baird, MD, PhD
		The internal carotid artery originates at the bifurcation of the common carotid artery at the level of the thyroid cartilage in the neck.
		The middle cerebral artery (MCA) is the direct continuation of the artery, while the anterior cerebral artery (ACA) branches medially at the level of the anterior clinoid process.
		The most common causes of arterial occlusion involving the major cerebral arteries are (1) emboli, most commonly arising from atherosclerotic arterial narrowing at the bifurcation of the common carotid artery, from cardiac sources, or from atheroma in the aortic arch and (2) a combination of atherosclerotic stenosis and superimposed thrombosis.

		The artery is separated from the bony wall of the carotid canal by a prolongation of dura mater, and is surrounded by a number of small veins and by filaments of the carotid plexus, derived from the ascending branch of the superior cervical ganglion of the sympathetic trunk.
		As the artery crosses the optic nerve it is accompanied by the nasociliary nerve, and is separated from the frontal nerve by the Rectus superior and Levator palpebræ superioris.
		The lacrimal artery is sometimes derived from one of the anterior branches of the middle meningeal artery.

	Medical Aspects: Blood Supply
		The vertebral arteries and the basilar are straight arteries and therefore not as subject to blockages due to the build up of cholesterol as are the internal carotids.
		As the vertebral and basilar are somewhat wide arteries and their course is relatively straight, they are not as subject to blockages caused by the build-up of cholesterol as the internal carotids.
		However, the basilar and posterior cerebral arteries may hemorrhage due to shearing injuries caused by accidents or pressure due to edema of the brain.

	NPEL: Vascular Disease
		The circle of Willis is composed principally of the anterior communicating artery that joins the two anterior cerebral arteries, and the two posterior communicating arteries, each of which joins a posterior cerebral artery with an ipsilateral carotid artery.
		On the other hand, because of the constancy of the anterior communicating artery, it is rare to develop a vascular insult in the distribution of the anterior cerebral artery due to occlusion of the ipsilateral carotid artery.
		Cerebral vascular disease causes 10% of all deaths annually, and is the third leading cause of death behind heart disease and cancer.

		The ACA supplies the whole of the medial surfaces of the frontal and parietal lobes, the anterior four fifths of the corpus callosum, the frontobasal cerebral cortex, the anterior diencephalon, and the deep structures.
		Often, ischemia in the distribution of the ophthalmic artery is transient in the setting of symptomatic internal carotid artery occlusion (ie, transient monocular blindness, occurring in approximately 25% of patients), but central retinal artery ischemia is relatively uncommon, presumably because of the efficient collateral supply.
		In Caucasians, the arterial occlusive disease typically involves the extracranial carotid arteries, and lesions in the middle and anterior cerebral arteries are usually of embolic origin.
