"superior division (utriculo-ampullary nerve): courses in the posterosuperior quadrant of the internal acoustic meatus, carrying sensory fibres from the utricle and hair cells of the superior and lateral semicircular canals"
"inferior division (saccular nerve): courses in the posteroinferior quadrant of the internal acoustic meatus to enter the vestibule, carrying sensory fibres from the saccule"
"singular nerve (posterior ampullary nerve): courses in the posteroinferior quadrant of the internal acoustic meatus and through the foramen singulare, carrying sensory fibres from the posterior semicircular canal 5"
"The vestibulocochlear nerve is the eighth (CN VIII) cranial nerve (TA: nervus vestibulocochlearis or nervus cranialis VIII). It exits the brainstem through the cerebellopontine angle, passing into the internal acoustic meatus as part of the acousticofacial bundle. Within the internal acoustic meatus, the nerve branches into cochlear and vestibular nerves to supply the cochlea and vestibule respectively. From these special sensory organs of the inner ear, the vestibulocochlear nerve transmits afferent impulses to the central nervous system encoding auditory stimuli, static (gravitational) equilibrium, and dynamic (rotational) equilibrium."
