Left Hemispheric Surface Distribution of the Cerebral Arteries

Surgical Correlation


Left hemispheric surface distribution of the cerebral arteries. The lateral surface of the left cerebral hemisphere is shown covered by branches of the anterior, middle, and posterior cerebral arterial system. The transverse venous sinus is shown positioned between the occipital lobes and cerebellum within the tentorium cerebelli. The anterior and middle cerebral arteries are terminal branches of the internal carotid. The anterior cerebral artery, the smaller terminal branch, supplies the medial aspect of the frontal lobes and the superior part of the parietal lobes. The middle cerebral arteries supply most of the lateral surface of the hemisphere, except the superior part of the parietal lobe and inferior part of the temporal and occipital lobes. The posterior cerebral arteries, terminal branches of the basilar artery, supply the occipital and posteromedial temporal lobes. (Image courtesy of PA Rubino)
