7 segments of the Internal Carotid

Circle of Willis (Circulus arteriosus cerebri s. 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
