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.

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.
