The basilar artery terminates by splitting into the left and right posterior cerebral arteries.
|Branches||Pontine arteries, anterior inferior cerebellar (AICA) and superior cerebellar arteries, and terminal posterior cerebral arteries.|
|Supplies||Pons, and superior and inferior aspects of the cerebellum.|
The two vertebral arteries and the basilar artery are sometimes together called the vertebrobasilar system, which supplies blood to the posterior part of the circle of Willis and joins with blood supplied to the anterior part of the circle of Willis from the internal carotid arteries.
Its branches from caudal to rostral include:
- anterior inferior cerebellar artery
- labyrinthine artery (<15% of people, usually branches from the anterior inferior cerebellar artery)
- pontine arteries
- superior cerebellar artery
A basilar artery stroke classically leads to locked-in syndrome.
