The posterior communicating artery supplies blood and oxygen to the brain in instances where the internal carotid or posterior cerebral arteries are blocked. However the latest neuroanatomical. Posterior cerebral artery syndrome is a condition whereby the blood supply from the posterior cerebral artery PCA is restricted leading to a reduction of the function of the portions of the brain supplied by that vessel.

The occipital lobe the inferomedial temporal lobe a large portion of the thalamus and the. The smaller branches of posterior cerebral artery transfer blood to midbrain. Upon reaching the lateral border of the pons the posterior cerebral artery curves around the cerebral peduncle to reach the medial surface of the cerebral hemispheres where it supplies the temporal and occipital lobes.

The posterior cerebral arteries provide blood to the occipital and temporal lobes. The posterior cerebral artery supplies blood to the occipital lobe and is not a cause of cranial nerve deficits. Part of the internal capsule Part of the basal ganglia.

Anterior and posterior circulations provide the. The posterior cerebral artery is susceptible to occlusion a sudden blockage usually resulting from a blood clot. Relay center for descending and ascending information.

Coming from the internal carotid artery this artery brings blood to most of the cerebral hemispheres but not the occipital lobes. The anterior circuit is supplied by the internal carotid arteries. Anterior inferior cerebellar artery AICA which supplies the middle portion of the cerebellum and then the basilar artery gives off the superior cerebellar artery which supplies the superior aspect of the cerebellum The basilar artery finally terminates in the two posterior cerebral arteries PCAs which give off the posterior communicating arteries which.
