|Artery: Basilar artery|
|The basilar artery (middle of figure) arises from the vertebral arteries and terminates when it bifurcates in the left and right posterior cerebral arteries.|
|The arteries of the base of the brain. Basilar artery labeled below center. The temporal pole of the cerebrum and the cerebellar hemisphere have been removed on the right side. Inferior aspect (viewed from below).|

|Supplies||Superior and inferior aspects of the cerebellum
|Branches||Anterior inferior cerebellar, posterior cerebral, superior cerebellar arteries and pontine branches|
The two vertebral arteries and the basilar artery are sometimes together called the vertebrobasilar system, which supplies blood to the posterior part of circle of Willis and anastomoses with blood supplied to the anterior part of the circle of Willis from the internal carotid arteries.
From the basilar artery arises the anterior inferior cerebellar artery (supplying the superior and inferior aspects of the cerebellum), as well as smaller branches for the supply of the pons (the pontine branches).
In under 15% of people the basilar artery gives rise to the labyrinthine artery.
