posterior cerebral artery


pos·te·ri·or ce·re·bral ar·ter·y

[TA] formed by the bifurcation of the basilar artery; it passes around the cerebral peduncle to reach the medial aspect of the hemisphere. For descriptive purposes it is divided into three parts, consisting of four segments: 1) precommunicating part (P1 segment of clinical terminology), which gives rise to posteromedial central arteries [TA], short circumferential arteries [TA], the thalamoperforating artery [TA], and the collicular artery [TA]; 2) the postcommunicating part (P2), which gives rise to posterolateral central arteries [TA], posterior medial choroidal branches [TA], posterior lateral choroidal branches [TA], peduncular branches [TA], and the thalamogeniculate artery [TA]; and 3) the terminal or cortical part consisting of the lateral occipital artery [TA] (P3) the branches of which serve the medial aspect of the temporal lobe and the medial occipital artery [TA] (P4), with branches that serve the medial surface of the occipital lobe; the latter includes calcarine and parietooccipital arteries. Synonym(s): arteria cerebri posterior [TA]

posterior cerebral artery

The end branch of the basilar artery; it runs around the sides of the midbrain, through the tentorium cerebelli, and along the temporal and occipital lobes to end in the calcarine fissure (the primary visual cortex). Its branches supply blood to the posterior hypothalamus, subthalamus, the choroid plexus of the third ventricle, the internal capsule, the ventral (inferior) surfaces of the temporal and occipital lobes, and parts of the thalamus and the midbrain. The posterior cerebral artery anastomoses with the circle of Willis via the posterior communicating artery. See: brain (Major arteries of the brain) and circle of Willis for illus. See also: artery
