The anterior inferior cerebellar artery arises from the basilar artery. From its origin, located near the junction between the pons and medulla oblongata, it travels posterolaterally around the brainstem and the inferior part of the cerebellum.
Along its course, the anterior inferior cerebellar artery gives off the labyrinthine artery, and it anastomoses with the posterior inferior cerebellar artery.
The anterior inferior cerebellar artery provides an arterial supply to the inferior parts of the cerebellum and pons, and the superior part of the medulla oblongata.
