View into the right side of the posterior cranial fossa depicting the relationship of the cerebellum and associated vasculature and cranial nerves. The facial nerve, nervus intermedius, and vestibulocochlear nerve can be observed coursing toward the opening of the internal auditory meatus in company with the labyrinthine artery, which supplies the inner ear. It is commonly a branch of the anterior inferior cerebellar artery. The glossopharyngeal, vagus, and spinal accessory nerves are seen converging on the jugular foramen. (Image courtesy of AL Rhoton, Jr.)
