Abbr | Name of Artery | Distribution
| ACA | Anterior Cerebral Artery | Supplies most medial portions of frontal lobes and superior medial parietal lobes
|
AComA | Anterior Communicating Artery | Connects the anterior cerebral arteries at their closest juncture
|
ICA | Internal Carotid Artery | Ascends through base of skull to give rise to the anterior and middle cerebral arteries, and connect with posterior half of circle of Willis via posterior communicating artery
|
MCA | Middle Cerebral Artery | Trifurcates into temporal, frontal, and parietal branches that supply most of the parenchyma of these lobes
|
PComA | Posterior Communicating Artery | Connects the anterior circle of Willis with the posterior cerebral artery of vertebral-basilar circulation posteriorly
|
PCA | Posterior Cerebral Artery | Supplies the occipital lobe and the inferior portion of temporal lobe. A branch supplies the choroid plexus.
|
SCA | Superior Cerebellar Artery | Supplies the dorsal cerebellum, pons, and midbrain
|
BA | Basilar Artery | Formed by the junction of the two vertebral arteries, it terminates as a bifurcation into the posterior cerebral arteries
|
AICA | Anterior Inferior Cerebellar Artery | Supplies the inferior cerebellum and portions of pons and medulla
|
VA | Vertebral Artery | The vertebrals emerge from the posterior base of skull and merge to form the basilar artery
|
PICA | Posterior Inferior Cerebellar Artery | Supplies the posterior cerebellum, choroid plexus in 4th ventricle, and portions of medulla
|
ASA | Anterior Spinal Artery | Descends along the anterior (ventral) aspect of the spinal cord
