Media file 4: The nerves of the internal auditory canal as observed in a cadaveric dissection are shown. The posterior wall of the internal auditory canal has been removed. F indicates the facial nerve. S is the superior vestibular nerve. VIII indicates the statoacoustic nerve as it leaves the brain stem, and P indicates the posterior ampullary nerve. The hollow arrow points to the posterior lip of the boney porous acusticus, and the solid arrow indicates the position of the vestibule. C indicates the cochlear aqueduct.
