Anterior cerebral artery : supply all the medial surface of the cerebral till parieto-occipital sulcus.+ and 1 inch of lateral surface
Middle cerebral artery : supply entire lateral surfaces of cortex except the 1 inch and occipital pole .
posterior cerebral artery : Supply occipital pole, and inferolateral surface of hemisphere .
