| 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
|
