Brainstem The brainstem is supplied by the vertebrobasilar circulation and their branches small branches of the posterior cerebral artery PCA and the anterior spinal artery. The middle cerebral artery MCA is one of the three major paired arteries that supply blood to the cerebrumThe MCA arises from the internal carotid and continues into the lateral sulcus where it then branches and projects to many parts of the lateral cerebral cortex.

Posterior Cerebral Artery Wikipedia

Its crucial purpose is to serve the.

. Its role is to provide blood supply to the brain. Based on a study of 1413 brains the classic anatomy of the circle is only seen in 345 of cases. Anterior cerebral artery supplies part of.

The left and right MCAs rise from. It also supplies blood to the anterior temporal lobes and the insular cortices. Middle cerebral artery Arteria cerebri media The middle cerebral artery MCA is a terminal branch of the internal carotid artery and is part of the anterior cerebral circulationThe MCA supplies many deep brain structures the majority of the lateral surface of the cerebral hemispheres and the temporal pole of the brainIt travels from the base of the brain through.

The posterior communicating artery is a location where aneurysms can potentially occur. The artery connects the internal carotid and the posterior cerebral arteries. The anterior circulation derives blood from the bilateral internal carotid arteries ICA and supplies blood to the majority of the cerebral hemispheres including the frontal lobes parietal lobes lateral temporal lobes and anterior part of deep cerebral hemispheres.

The posterior communicating artery PCOM is a part of a group of arteries in the brain known as the circle of Willis. It is formed at the junction of the pons and medulla by the convergence of the dual vertebral arteries. The basilar artery is a vital vessel contributing to the posterior cerebral circulation.

The blood supply to the brain divides into an anterior and posterior circulation. Posterior communicating artery acts as an anastomotic connecting vessel in the Circle of Willis see Circle of Willis below. Recurrent artery of Heubner arising as a large branch from the anterior cerebral artery supplies the caudate nucleus.

Considerable anatomic variation exists in the circle of Willis. The vertebral arteries join the basilar artery to form the vertebrobasilar system which supplies blood to the posterior portion of the circle of Willis. In one common variation the proximal part of the posterior cerebral artery is narrow and its ipsilateral posterior communicating artery is large so the internal carotid artery supplies the posterior cerebrum.

Anterior choroidal artery supplies structures in the brain important for motor control and vision.
