An antechamber to the inner ear that amplifies sound vibrations of the eardrum and transmits them to the cochlea.
That part of the ear consisting of air-filled space in the temporal bone and extending from the tympanic membrane, which separates it from the external ear, to the inner ear. It contains three small bones (the malleus, incus, and stapes) that transmit sound vibrations from the tympanic membrane to the inner ear. The middle ear is connected to the pharynx through the Eustachian tube.
The part of the ear that consists of an air-filled space within the petrous part of the temporal bone. It is lined with mucous membrane and is connected to the pharynx by the Eustachian tube and to the outer ear by the eardrum (tympanic membrane). Within the middle ear are three bones (the auditory ossicles), which transmit sound vibrations from the outer ear to the inner ear.
That portion of the ear lying between the tympanic membrane and the inner ear. It contains the ossicles, the three small bones that transmit sound.
The tympanic cavity, an irregular air-filled space in the temporal bone. Anteriorly, it communicates with the eustachian tube, which forms an open channel between the middle ear and the cavity of the nasopharynx. Posteriorly, the middle ear opens into the mastoid antrum, which in turn communicates with the mastoid sinuses. Of the three potential openings into the middle ear, two— the tympanic membrane and the round window — are covered. The third one is the eustachian tube. Three ossicles (small bones) joined together, the malleus, incus, and stapes, extend from the tympanic membrane to the oval window of the inner ear.
The petite space situated betwixt the tympanic membrane and the oval window, which harbors the trio of minuscule auditory ossicles responsible for the perception of sound.
