Glossopharyngeal nerve 16 Cranial nerve III, Oculomotor nerve 17 Cranial nerve I, Olfactory nerve in the rostral midbrain, which serves as an important relay point for auditory information as it travels from the inner ear to the auditory cortex largest pair of cranial nerves, supplying the front part of the head and dividing into the ophthalmic, maxillary, and mandibular nerves. supplying the superior oblique muscle of the eyeball the uppermost part of the midbrain, lying to the rear of the cerebral aqueduct. transmitting impulses to the brain from the retina at the back of the eye each of twelve pairs of nerves which arise directly from the brain, not from the spinal cord, and pass through separate apertures in the skull supplying the muscles concerned with the lateral movement of the eyeballs supplying the tongue and pharynx the central trunk of the mammalian brain, consisting of the medulla oblongata, pons, and midbrain, and continuing downward to form the spinal cord transmitting impulses to the brain from the smell receptors in the mucous membrane of the nose supplying most of the muscles around and within the eyeballs in the rostral midbrain that is involved in incorporating environmental stimuli and coordinating gaze of both eyes and head movements supplying the heart, lungs, upper digestive tract, and other organs of the chest and abdomen supplying the facial muscles and the tongue conveying sensory impulses from the organs of hearing and balance in the inner ear to the brain. branches into the vestibular and cochlear nerve supplying the muscles of the tongue supplying the sternocleidomastoid and trapezius muscles 1 Anosmia 2 Foramen rotundum 3 Semicircular canals 4 Saccule 5 Perilymph 6 Superior orbital fissure 7 Scala vestibuli 8 Endolymph 9

Cribriform plate 21 Vestibule 22 Auditory canal 23 Hypoglossal foramen 24 Superior orbital fissure 25 Jugular foramen 26 Bony labyrinth the most common facial nerve disorder where all divisions of the nerve are impaired within a few hours or days and then gradually recover exit foramen for cranial nerve XII exit foramen for cranial nerves VII and VIII one of the otoliths, located in the vestibule, which is sensitive to linear acceleration and is positioned in the vertical plane loss of the sense of smell exit foramen for V3 branch of cranial nerve V the spiral cavity of the inner ear containing the organ of Corti, which produces nerve impulses in response to sound vibrations the fluid between the membranous labyrinth of the ear and the bone that encloses it exit foramen for cranial nerve VI exit foramen for V2 branch of cranial nerve V three fluid-filled bony channels in the inner ear and provide information about orientation to the brain to help maintain balance the lower bony passage of the cochlea the inner labyrinth that is suspended within the bony labyrinth and filled with endolymph the fluid in the membranous labyrinth of the ear the inner ear composed of the bony labyrinth and the membranous labyrinth the centralized structure of the bony labyrinth from which the semicircular canals arise exit foramen for cranial nerve I one of the otoliths, located in the vestibule, which is sensitive to linear acceleration and positioned in the horizontal plane the outer labyrinth comprised of bone and filled with perilymph involving one or more of the branches of the trigeminal nerves, and often causing severe pain exit foramen for cranial nerves IX, X, and XI a membrane forming part of the organ of hearing, which vibrates in response to sound waves. exit foramen for cranial nerves II, IV, and V1 branch of cranial nerve V the upper bony passage of the cochlea the central duct of the cochlea in the inner ear, containing the sensory cells and separated from the scala tympani and scala vestibuli by membranes. exit foramen for cranial nerve II 1 Meniere’s disease 2 Vestibular neuritis 3 Scarpa’s ganglion 4 Primary auditory cortex 5 Maculae 6 Tinnitus 7 Acoustic neuroma 8 Central vestibular disorders 9 Benign paroxysmal positional vertigo 10 Peripheral vestibular disorders 11 Vestibular labyrinthitis 12 Conductive hearing loss 13 Ampullae 14 Otoliths 15 Crista ampullaris 16 Vestibular nuclei 17 Organ of Corti 18 Cupula 19 Nystagmus 20 Sensorineural hearing loss a sensory structure located inside the otoliths, the utricle and saccule, that detect linear acceleration and head tilt causes a false sensation of spinning or movement disorder that affects the vestibular nerve and causes prolonged vertigo in the absence of hearing loss the primary sensory structure within the ampulla containing hair cells important for adjustment of posture, muscle tone, and eye position in response to movements of the head in space a peripheral vestibular disorder that is caused by an abnormality in the labyrinth where fluid imbalance causes severe vertigo and hearing loss a peripheral vestibular disorder that affects the labyrinth and causes prolonged vertigo along with hearing loss ringing or buzzing in the ears the bulge at the base of each semicircular canal containing the crista ampullaris and cupula vestibular disorders involving anatomy in the inner ear a gelatinous mechanoreceptor inside the ampulla of the semicircular canal each of three small oval calcareous bodies in the inner ear of vertebrates, involved in sensing gravity and movement Brodmann's area 41 and the transverse gyrus of Heschl hearing loss caused by disorders of the cochlea or cranial nerve VIII hair cells and supporting cells of the cochlea the location of cell bodies for the vestibular portion of cranial nerve VIII hearing loss caused by abnormalities of the external auditory canal or middle ear vestibular disorders involving the brainstem or cerebellum rapid involuntary movements of the eyes a vestibular schwannoma that is a benign, slow-growing tumor, that develops in and around cranial nerve VIII
