middle ear

the tympanic cavity with the auditory ossicles contained in an irregular space in the temporal bone. It is separated from the external ear by the tympanic membrane and from the inner ear by the oval window. The auditory (eustachian) tube carries air from the posterior nasopharynx into the middle ear. Also called tympanic cavity. Compare external ear, internal ear.

Middle ear

middle ear

The middle of the three parts of the ear, consisting of an air-filled cavity bound externally by the tympanic membrane and containing three ossicles that vibrate in response to sound waves, passing the amplified sound to the inner ear at the round window.

(tim-pan'ik kav'i-tē) [TA]
An air chamber in the temporal bone containing the ossicles; it is lined with mucous membrane and is continuous with the auditory tube anteriorly and the tympanic antrum and mastoid air cells posteriorly.

(ēr) [TA]
The organ of hearing: composed of the external ear, which includes the auricle and the external acoustic, or auditory, meatus; the middle ear, or the tympanic cavity with its ossicles; and the internal ear or inner ear, or labyrinth, which includes the semicircular canals, vestibule, and cochlea.

middle ear

The narrow cleft within the temporal bone lying between the inside of the ear drum and the outer wall of the inner ear. The middle ear is lined with mucous membrane, contains the chain of three auditory OSSICLES and is drained into the back of the nose by the EUSTACHIAN TUBE. It is a common site of infection, which gains access by way of the tube. Middle ear infection is called OTITIS MEDIA. Also known as the tympanic cavity.

Middle ear

The cavity or space between the eardrum and the inner ear. It includes the eardrum, the three little bones (hammer, anvil, and stirrup) that transmit sound to the inner ear, and the eustachian tube, which connects the inner ear to the nasopharynx (the back of the nose).
