- The Posterior Cerebral Artery
- The Basilar Artery
- The superior cerebellar artery
- The anterior inferior cerebellar artery

Explanation with High Yield Facts:
The AICA territory includes the middle cerebellar peduncle, fifth nerve sensory nucleus and tract, seventh nerve and nucleus, eighth nerve, vestibular nuclei and the descending sympathetic tracts. AICA-related lateral pontine infarction produces a syndrome similar to Wallenberg's; but instead of hoarseness, palatal weakness and loss of taste, there is ipsilateral facial paralysis and deafness.
