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

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 a gelatinous mechanoreceptor inside the ampulla of the semicircular canal the primary sensory structure within the ampulla containing hair cells Brodmann's area 41 and the transverse gyrus of Heschl important for adjustment of posture, muscle tone, and eye position in response to movements of the head in space ringing or buzzing in the ears hair cells and supporting cells of the cochlea vestibular disorders involving the brainstem or cerebellum a sensory structure located inside the otoliths, the utricle and saccule, that detect linear acceleration and head tilt a peripheral vestibular disorder that affects the labyrinth and causes prolonged vertigo along with hearing loss hearing loss caused by disorders of the cochlea or cranial nerve VIII each of three small oval calcareous bodies in the inner ear of vertebrates, involved in sensing gravity and movement causes a false sensation of spinning or movement hearing loss caused by abnormalities of the external auditory canal or middle ear the location of cell bodies for the vestibular portion of cranial nerve VIII a peripheral vestibular disorder that is caused by an abnormality in the labyrinth where fluid imbalance causes severe vertigo and hearing loss vestibular disorders involving anatomy in the inner ear disorder that affects the vestibular nerve and causes prolonged vertigo in the absence of hearing loss
