colliculus 16 Cranial nerve XII, Hypoglossal nerve 17 Cranial nerve IV, Trochlear nerve supplying the heart, lungs, upper digestive tract, and other organs of the chest and abdomen supplying the muscles concerned with the lateral movement of the eyeballs supplying the muscles of the tongue supplying the tongue and pharynx supplying the superior oblique muscle of the eyeball 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 the central trunk of the mammalian brain, consisting of the medulla oblongata, pons, and midbrain, and continuing downward to form the spinal cord the uppermost part of the midbrain, lying to the rear of the cerebral aqueduct. transmitting impulses to the brain from the smell receptors in the mucous membrane of the nose supplying the sternocleidomastoid and trapezius muscles supplying the facial muscles and the tongue largest pair of cranial nerves, supplying the front part of the head and dividing into the ophthalmic, maxillary, and mandibular nerves. 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 conveying sensory impulses from the organs of hearing and balance in the inner ear to the brain. branches into the vestibular and cochlear nerve in the rostral midbrain that is involved in incorporating environmental stimuli and coordinating gaze of both eyes and head movements transmitting impulses to the brain from the retina at the back of the eye supplying most of the muscles around and within the eyeballs 1 Labyrinth 2 Hypoglossal foramen 3 Jugular foramen 4 Perilymph 5 Auditory canal 6 Semicircular canals 7 Foramen rotundum 8 Cochlea 9 Membranous labyrinth 10 Trigeminal neuralgia 11 Scala media or cochlear duct 12 Scala vestibuli 13 Endolymph 14 Superior orbital fissure 15 Scala tympani 16 Anosmia 17 Utricle 18 Superior orbital fissure 19 Bell’s palsy 20 Bony labyrinth 21 Foramen ovale 22 Saccule 23 Tympanic membrane 24 Vestibule 25 Optic canal 26 Cribriform plate three fluid-filled bony channels in the inner ear and provide information about orientation to the brain to help maintain balance the fluid between the membranous labyrinth of the ear and the bone that encloses it exit foramen for cranial nerves IX, X, and XI exit foramen for V2 branch of cranial nerve V one of the otoliths, located in the vestibule, which is sensitive to linear acceleration and is positioned in the vertical plane the centralized structure of the bony labyrinth from which the semicircular canals arise exit foramen for cranial nerves VII and VIII the spiral cavity of the inner ear containing the organ of Corti, which produces nerve impulses in response to sound vibrations the fluid in the membranous labyrinth of the ear exit foramen for cranial nerve VI a membrane forming part of the organ of hearing, which vibrates in response to sound waves. loss of the sense of smell one of the otoliths, located in the vestibule, which is sensitive to linear acceleration and positioned in the horizontal plane exit foramen for V3 branch of cranial nerve V exit foramen for cranial nerve I 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 XII the inner labyrinth that is suspended within the bony labyrinth and filled with endolymph exit foramen for cranial nerves II, IV, and V1 branch of cranial nerve V exit foramen for cranial nerve II the inner ear composed of the bony labyrinth and the membranous labyrinth involving one or more of the branches of the trigeminal nerves, and often causing severe pain the upper bony passage of the cochlea the lower bony passage of the cochlea the most common facial nerve disorder where all divisions of the nerve are impaired within a few hours or days and then gradually recover the outer labyrinth comprised of bone and filled with perilymph 1 Conductive hearing loss 2 Peripheral vestibular disorders 3 Nystagmus 4 Maculae 5 Cupula 6 Organ of Corti 7

cortex 15 Vestibular nuclei 16 Tinnitus 17 Vestibular neuritis 18 Crista ampullaris 19 Acoustic neuroma 20 Otoliths Brodmann's area 41 and the transverse gyrus of Heschl each of three small oval calcareous bodies in the inner ear of vertebrates, involved in sensing gravity and movement a gelatinous mechanoreceptor inside the ampulla of the semicircular canal disorder that affects the vestibular nerve and causes prolonged vertigo in the absence of hearing loss hearing loss caused by abnormalities of the external auditory canal or middle ear a peripheral vestibular disorder that is caused by an abnormality in the labyrinth where fluid imbalance causes severe vertigo and hearing loss a vestibular schwannoma that is a benign, slow-growing tumor, that develops in and around cranial nerve VIII the bulge at the base of each semicircular canal containing the crista ampullaris and cupula vestibular disorders involving anatomy in the inner ear a peripheral vestibular disorder that affects the labyrinth and causes prolonged vertigo along with hearing loss vestibular disorders involving the brainstem or cerebellum hearing loss caused by disorders of the cochlea or cranial nerve VIII the location of cell bodies for the vestibular portion of cranial nerve VIII ringing or buzzing in the ears rapid involuntary movements of the eyes important for adjustment of posture, muscle tone, and eye position in response to movements of the head in space causes a false sensation of spinning or movement the primary sensory structure within the ampulla containing hair cells a sensory structure located inside the otoliths, the utricle and saccule, that detect linear acceleration and head tilt hair cells and supporting cells of the cochlea
