| cerumin/o | wax |
| myring/o | eardrum |
| tympan/o | eardrum |
| salping/o | tube |
| -acusis | hearing condition |
| BAEP | brainstem auditory evoked potential |
| BAER | brainstem auditory evoked response |
| ENT | ear, nose, and throat |
| PE | polyethylene |
| TM | tympanic membrane |
| auricle | projected part of the external ear |
| pinna | projected part of the external ear |
| external acoustic meatus | external passage for sounds collected from the auricle to the tympanic membrane |
| Middle Ear | structures in the middle of the ear that vibrate sound from the tympanic membrane to the internal ear |
| tympanic membrane | drum-like structure that receives sound collected in the external acoustic meatus and amplifies it through the middle ear |
| oval window | membrane that covers the opening between the middle ear and internal ear |
| cochlea | coiled tubular structure of the internal ear that contains the spiral organ of Corti; cochlear duct is the membranous tube within the cochlea |
| organ of Corti | structure located in the cochlea; contains receptors (hair cells) that receive vibrations and generate nerve impulses for hearing |
| vestibule | middle part of the internal ear, in front of the semicircular canals and behind the cochlea, that contains the utricle and the saccule; functions to provide body balance and equilibrium |
| semicircular canals | three canals within the inner ear that contain specialized receptor cells that generate nerve impulses with body movement |
| malleus (hammer) | first of the three auditory ossicles of the middle ear |
| incus (anvil) | middle of the three auditory ossicles of the middle ear |
| stapes (stirrup) | last of the three auditory ossicles of the middle ear |
| tuning fork | a two-pronged, fork-like instrument that vibrates when struck; used to test hearing, especially bone conduction; (eg. Webber test & Rinne test) |
| otoscope | instrument for examining the ear |
| otoscopy | use of an otoscope to examine the external acoustic meatus and tympanic membrane |
