Due to the anastomotic circle of Willis the posterior circulation connects via the posterior communicating arteries to the anterior circulation. The main function of the posterior communicating artery is to provide an alternative route to the brain blood supply in case there is a blockage of the internal carotid or vertebral arteries. The posterior communicating artery supplies blood and oxygen to the brain in instances where the internal carotid or posterior cerebral arteries are blocked.

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 posterior cerebral artery curls around the cerebral peduncle and passes above the tentorium to supply the posteromedial surface of the temporal lobe and the occipital lobe. A nurse is measuring the BP of a hypertensive obese patient who has been admitted to the hospital for increased blood glucose levels.

Inferior in the cerebrum. A solid understanding of the pathophysiology of a posterior cerebral artery PCA stroke as well as the syndrome relating to it requires adequate knowledge of the structures and vascular anatomy of the brain. This region includes calcarine cortex often known as the primary visual cortex.

Anterior cerebral artery supplies part of. However the latest neuroanatomical. The posterior cerebral artery supplies blood to the back portions of the brain since posterior means back such as the occipital lobe and the.

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 smaller branches of posterior cerebral artery transfer blood to midbrain region of the optic path ways thalamus and. It also gives rise to the thalamoperforating vessels.

The posterior communicating artery connects the internal carotid with the posterior cerebral arteries thus connecting the anterior and posterior cerebral circulations. The posterior cerebral artery supplies blood to the occipital lobe and is not a cause of cranial nerve deficits. The two arteries originate from the distal end of the basilar artery where it bifurcates into the left and right posterior cerebral arteries.

These anastomose with the middle cerebral arteries and internal carotid arteries via the. Posterior communicating artery acts as an anastomotic connecting vessel in the Circle of Willis see Circle of Willis below. At the level of the midbrain the basilar artery bifurcates to form the two posterior cerebral arteries PCA.

Part of the internal capsule Part of the basal ganglia. If an embolus travels in a vertebral branch it may stop where the vertebral arteries join to form the basilar artery. This can cause a wide variety of symptoms including vision loss dizziness.

A posterior division includes the two terminal branches of the PCA. Anterior choroidal artery supplies structures in the brain important for motor control and vision. And the calcarine artery which supplies the visual cortex inferior cuneus and part of the lingual gyrus.
