The posterior inferior cerebellar artery (PICA), the largest branch of the vertebral, is one of the three main arterialblood supplies for the cerebellum.
The medial branch is continued backward to the notch between the two hemispheres of the cerebellum; while the lateral supplies the under surface of the cerebellum, as far as its lateral border, where it anastomoses with the anterior inferior cerebellar and the superior cerebellar branches of the basilar artery.
