POSTERIOR CEREBRAL ARTERY

an artery within the brain which stems from the terminal bifurcation of the basilar artery and crosses above the oculomotor nerve to go around the midbrain above the level of the tentorium cerebelli. Its departments provide blood to the area of the third ventricle, inclusive of the thalamus and choroid plexus, the occital lobe's posterior surface, and the fusiform, lingual, and inferior temporal gyri.
