| acous/o | | a waxy substance secreted by glands located throughout the external canal |
| audi/o | | tube connecting the middle ear to the pharynx (throat) |
| aur/i | | hearing |
| ot/o | | membrane that covers the opening between the middle ear and internal ear |
| myring/o | | coiled tubular structure of the internal ear that contains the spiral organ of Corti; cochlear duct is the membranous tube within the cochlea |
| tympan/o | | drum-like structure that receives sound collected in the external acoustic meatus and amplifies it through the middle ear |
| aer/o | | projected part of the external ear |
| salping/o | | tube |
| cerumin/o | | middle of the three auditory ossicles of the middle ear |
| -acusis | | drum-like structure that receives sound collected in the external acoustic meatus and amplifies it through the middle ear |
| External Ear | | air or gas |
| auricle | | last of the three auditory ossicles of the middle ear |
| pinna | | eardrum |
| external auditory meatus | | external passage for sounds collected from the auricle to the tympanic membrane |
| cerumen | | eardrum |
| Middle Ear | | ear |
| tympanic membrane | | intricate, fluid-filled, intercommunicating bony and membranous passages that function in hearing by relaying sound waves to auditory nerve fibers on a path to the brain for interpretation; also sense body movement and position to maintain balance and equilibrium |
| tympanum | | hearing condition |
| malleus (hammer) | | outer structures of the ear that collect sound |
| incus (anvil) | | ear |
| stapes (stirrup) | | structure located in the cochlea; contains receptors (hair cells) that receive vibrations and generate nerve impulses for hearing |
| organ of Corti | | external passage for sounds collected from the auricle to the tympanic membrane |
| endolymph | | structures in the middle of the ear that vibrate sound from the tympanic membrane to the internal ear |
| perilymph | | hearing |
| cochlea | | first of the three auditory ossicles of the middle ear |
| labyrinth | | fluid that fills the bony labyrinth of the internal ear |
| Internal ear | | wax |
| oval window | | fluid within the membranous labyrinth of the internal ear |
| auditory tube | | intricate, fluid-filled, intercommunicating bony and membranous passages that function in hearing by relaying sound waves to auditory nerve fibers on a path to the brain for interpretation; also sense body movement and position to maintain balance and equilibrium |
| eustachian tube | | tube connecting the middle ear to the pharynx (throat) |
