Willisi) – Thomas Willis: – Ophthalamic Artery – Anterior Cerebral Artery – Middle Cerebral Artery – Anterior Choroid Artery – Posterior Communicating Artery – Posterior Cerebral Artery (Basillary Artery) Cerebral Part of Internal Carotid: – Anterior Cerebral Artery ○ Run along the longitudinal cerebral fissure, supplying: § Medial surface of frontal adn parietal lobe § Superior frontal gyrus § Superior parietal lobule § Upper part of post and pre central gyrus § Gyrus Rectus (Straight gyrus) – Middle Cerebral Artery ○ If occluded will cause middle cerebral artery syndrome ○ Supplies: § Insula § Lentiform nucleus § Caudate nucleus § Internal Capsule § Superior and middle Temporal Gyrus § Large area of superolateral surface of the hemispheres – Anterior Choroid artery ○ Goes backwards to form a choroid plexus in lateral and third ventricle – Posterior Cerebral Artery ○ From basilar artery. Supplies: § Occipital Lobe Inferior Temporal Gyrus
