====== Basilar artery branches ======

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).

The [[anterior inferior cerebellar artery]] ([[AICA]]).

In under 15% of people, the basilar artery gives rise to the [[labyrinthine artery]].

Pontine branches

[[Superior cerebellar artery]].

[[Posterior cerebral artery]].

[[Trigeminocerebellar artery]].

Proximally, the basilar artery joins the two internal carotid arteries and other communicating arteries to form a complete anastomotic ring at the base of the brain known as the [[circle of Willis]].
