PICA stands for which artery?

Explanation:
PICA stands for the Posterior Inferior Cerebellar Artery, a branch of the vertebral artery in the posterior circulation. It supplies the inferior surface of the cerebellum (and parts of the lateral medulla), so this name matches the artery described by the abbreviation. Knowing the territory helps: the posterior inferior cerebellar region is distinct from the anterior inferior cerebellar region (which supplies the anterior-inferior cerebellum and has different clinical signs), from the basilar artery (the major trunk that gives rise to several branches), and from the vertebral artery (the vessel that gives rise to PICA but is not itself PICA).
