name 3 auditory ossicles
malleus (hammer), incus (anvil), stapes (stirrup)
when ear bones become hard and fuse into one another, hardening (stiffening) condition of the ear structures characterized by progressive deafness
otosclerosis
inner ear is also called
labyrinth
3 regions of labyrinth
semi-circular canals, vestibule, cochlea
8th cranial nerve, assists in hearing
vestibulocochlear (acoustic) nerve
auditory tube (AKA)
Eustachian tube

presby
old
earwax, the yellowish substance secreted by the glands in the auditory canal of the external ear
cerumen
-cle
little, tiny, small
inflammation of the external ear
otitis externa
inflammation of the middle ear
otitis media
inflammation of the inner ear
otitis interna
collects and directs sound waves into auditory canal and then into tympanic membrane
auricle (pinna)
numerous glands line this canal and secrete cerumen to lubricate and protect ear
external auditory canal (external acoustic meatus)
contains the ossicles, has several openings, is lined with mucous membrane
middle ear
transmits sound vibrations from tympanic membrane to cochlea. equalizes external/internal air pressure on tympanic membrane
middle ear
allows us to hear/hearing organ, contains hair cell sensory receptors, contains organ of corti
cochlea
where is perilymph found
in pouches of vestibule (urticle and saccule)
contain nerve endings in the form of hair cells that note changes in the position of the head
semicircular canals
BC
bone conduction
ENT
ear, nose, throat (otorhinolaryngology)
HD
hearing distance
OM
otitis media
TM
tympanic membrane
clear fluid contained within the labyrinth of the ear
endolymph
pertaining to the sense of hearing
acoustic, auditory
study of hearing disorders
audiology
medical instrument used to measure hearing
audiometer
pertaining to the ear
aural, otic
serum fluid within labyrinth of the ear, receives sound first and transfers to endolymph
perilymph
clear fluid within the labyrinth of the ear
endolymph
external portion of ear, known as pinna
auricle
tumorlike mass filled with epithelial cells and cholesterol
cholesteatoma
portion of the inner ear shaped like a snail shell, contains organ of Corti
cochlea
helps in maintaining equalibrium, bony structure located between cochlea and the three semi-circular canals, contains urticle and saccule
vestbule
state of balance
equilibrium
narrow tube between middle ear and throat that serves to equalize pressure on both sides of eardrum
eustachian tube
-ory
pertaining to
middle of the ossicles
incus (anvil)
labyrinth, the inner ear is made up of
vestibule, cochlea, semicircular canals
largest of the 3 ossicles
malleus (hammer)
pain in mastoid process (the bony protuberance of skull near ear)
mastoidalgia
abnormality of inner ear causing a host of symptoms including vertigo, tinnitus, fluctuating hearing loss and sensation of pressure or pain in affected ear
Meniere’s disease
surgical excision of tympanic membrane
myringectomy
small bone, any one of the 3 bones of middle ear
ossicle
pertaining to the ear
otic, aural
pain in the ear, earache
otodynia, otalgia
stapes is attached to
oval window
ear stone
otolith
pus in the ear
otopyorrhea
study of the ear nose throat and larynx
otorhinolaryngology
impairment of hearing that occurs with aging
presbycusis
sensation of ringing or roaring sounds in one or both ears, symptom associated with damage to auditory canals in inner ear
tinnitus
tests for tinnitus and vertigo (tests whether we are able to maintain balance)
falling test
surgical operation in which a new opening is made in labyrinth of the inner ear to restore hearing
fenestration
surgical excision of tympanic membrane
tympanectomy, myringectomy
sensation of instability and loss of equilibrium, patients feel like they are spinning in space or objects around them are spinning. caused by disturbance in semicircular canal or vestibular nuclei of the brainstem
vertigo
(Dx and lab) response to auditory stimuli (sound) that can be measured independently of the patient’s subjective response. uses electroencephalograph
auditory-evoked response
(Dx & lab) recording eye movement in response to specific stimuli such as sound, nused to determine presence and location of lesion in the vestibule
electronystagomography
(Dx/lab) visual examination of external auditory canal and tympanic membrane via an otoscope
otoscopy
bony structure located between cochlea and the three semi-lunar canals
vestibule
method of testing hearing by the use of a tuning fork. to distinguish conductive and perceptive hearing loss
tuning fork test
-cusis
hearing
