CN VIII Course


Fibers that make up CN VIII travel from the spiral and vestibular ganglions in the inner ear to the inner auditory canal. It then exits the internal auditory canal with CN VII where it parallels the cerebellopontine angle cistern until reaching the brainstem at the pontomedullary junction. Vestibulocochlear nuclei are located in the pons and medulla.
