The middle ear is the portion of the ear medial to the eardrum, and distal to the oval window of the cochlea (of the inner ear). The mammalian middle ear contains three ossicles (malleus, incus, and stapes), which transfer the vibrations of the eardrum into waves in the fluid and membranes of the inner ear .
The ear is structurally divided into three parts: the external, middle and internal ear. The middle ear is an air-filled pressurized space within the petrous portion of the temporal bone, extending from the tympanic membrane (eardrum) to the lateral wall of the internal ear.
The main function of the middle ear is to carry sound waves from the outer ear to the inner ear, which contains the cochlea and where sound input can be communicated to the brain. Sound waves are funneled into the outer ear and strike the tympanic membrane, causing it to vibrate.
An ear infection (sometimes called acute otitis media) is an infection of the middle ear, the air-filled space behind the eardrum that contains the tiny vibrating bones of the ear. Children are more likely than adults to get ear infections.
Also known as the tympanic cavity, the middle ear is an air-filled, membrane-lined space located between the ear canal and the Eustachian tube, cochlea, and auditory nerve.
The human ear is composed of three parts – the external/outer ear, middle ear, and internal/inner ear. The middle ear region holds the three smallest bones of the body, collectively known as auditory ossicles.
Middle ear. Your middle ear begins on the other side of your tympanic membrane (eardrum). There are three tiny bones in this area — the malleus, incus and stapes. (Healthcare providers refer to these three bones as the ossicles.) They transfer sound vibrations from your eardrum to your inner ear.
The middle ear is a complex system of openings and canals placed mostly within the temporal bone. Its function is to transfer vibrations of the tympanic membrane into sound waves and pass them to the internal ear.
The major function of the middle ear is to match relatively low-impedance airborne sounds to the higher-impedance fluid of the inner ear. The term “impedance” in this context describes a medium's resistance to movement.
The middle ear connects to the back of the nose and upper part of the throat by a narrow channel called the auditory tube, also called the eustachian tube. The tube opens and closes at the throat end to keep the pressure the same in the middle ear and in the environment and drain fluids.
