The anterior circuit is supplied by the internal carotid arteries.

The posterior cerebral artery is one of a pair of cerebral arteries that supply oxygenated blood to the occipital lobe part of the back of the human brain. These anastomose with the middle cerebral arteries and internal carotid arteries via the. It also gives rise to the thalamoperforating vessels.

If an embolus travels in a vertebral branch it may stop where the vertebral arteries join to form the basilar artery. The posterior cerebral artery via its cortical branches supplies the inferior and medial surfaces of the temporal and occipital lobes together with a small area on the lateral surface of the hemisphere.

The focus of this article will be to discuss the major arteries that supply the brain. 3 rows Upon reaching the lateral border of the pons the posterior cerebral artery curves around the. They supply the temporal lobe and occipital lobes of the left cerebral hemisphere and the right hemisphere.

The posterior cerebral artery supplies blood to the back portions of the brain since posterior means back such as the occipital lobe and the. At the level of the midbrain the basilar artery bifurcates to form the two posterior cerebral arteries PCA. More often however it keeps going traversing the basilar which has a large diameter and is arrested at the upper.

The artery also provides blood supply to several subcortical structures of the cerebrum.

Middle cerebral artery b. From its origin the posterior cerebral artery curves laterally. The posterior circuit is supplied by the vertebrobasilar system.

Due to the anastomotic circle of Willis the posterior circulation connects via the posterior communicating arteries to the anterior circulation. It arises from the basilar artery and connects with the ipsilateral middle cerebral artery and internal carotid artery via the posterior communicating artery. The two arteries originate from the distal end of the basilar artery where it bifurcates into the left and right posterior cerebral arteries.

Posterior inferior cerebellar artery The blood vessels arising from the branches of the Circle of Willis supply parts of the cerebrum except a. Several branches from the basilar artery originate here and go onto supply the cerebellum and pons. Supplies inferior and medial temporal and occipital cortex including the visual cortex.

The posterior cerebral circulation or simply posterior circulation is the blood supply to the posterior portion of the brain including the occipital lobes cerebellum and brainstem. The posterior cerebral artery PCA supplies the occipital lobe the lower part of the temporal lobe and various deep structures including the thalamus and the posterior limb of the internal capsule.
