This area contains the calcarine cortex also known as the primary visual cortex.

. At the level of the midbrain the basilar artery bifurcates to form the two posterior cerebral arteries PCA. 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. The two arteries originate from the distal end of the basilar artery where it bifurcates into the left and right posterior cerebral arteries.

Vascular Supplies of the Deep Cerebral Structures see figures 108 and 109 pp 374-375 for visual depiction of information provided below Middle Cerebral Artery. The PCA supplies the occipital lobes inferomedial portions of the temporal lobes midbrain thalamus and deep structures including. Vertebral Artery The vertebral artery supplies blood to the posterior part of the circle of Willis.

The middle cerebral artery supplies blood to the cerebrum and is. The posterior communicating artery PCOM is a part of a group of arteries in the brain known as the circle of Willis. 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.

It also gives rise to the thalamoperforating vessels. These anastomose with the middle cerebral arteries and internal carotid arteries via the. The posterior cerebral artery is part of the Circle of Willis a ring or circle of arteries located at the base of the brain.

Posterior circulation is supplied by the vertebral arteries VA posterior inferior cerebellar arteries PICA basilar artery BA anterior inferior cerebellar arteries AICA pontine branches of the basilar artery superior cerebellar arteries SCA PCA and PCOM. The posterior cerebral artery supplies blood to the back portions of the brain since posterior means back such as the occipital lobe and the. In the vast majority of cases however the PCA is responsible for the supply of the mesial Occipital inferomesial Parietal and inferior Temporal lobes as well as the choroid plexus of the lateral together with the anterior choroidal and third ventricles.

More often however it keeps going traversing the basilar which has a large diameter and is arrested at the upper. The posterior cerebral arteries PCA arise from the basilar artery 70 of the time from the posterior communicating arteries 20 of the time and a mix of the two for the remaining 101 Because the occipital lobe the primary visual processing center of the mammalian brain is mainly supplied by PCA damage to these vessels can result in a variety of pathology. Supplies inferior and medial temporal and occipital cortex including the visual cortex.

The posterior cerebral artery supplies blood to the center of the occipital lobes the inferior sections of the temporal lobes the brain stem and the cerebellum. 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. 3 rows Upon reaching the lateral border of the pons the posterior cerebral artery curves around the.

If an embolus travels in a vertebral branch it may stop where the vertebral arteries join to form the basilar artery. Any impairment in the vertebral artery leads to cranial nerve deficits. Due to the anastomotic circle of Willis the posterior circulation connects via the posterior communicating arteries to the anterior circulation.

The posterior cerebral artery PCA is one of a pair of arteries that supply oxygenated blood to the occipital lobe part of the back of the human brain. The artery connects the internal carotid and the posterior cerebral arteries. One may also ask which of the following Gyral structures is supplied by the posterior cerebral artery.

Its role is to provide blood supply to the brain.
