The middle ear, also known as the tympanic cavity, is the air-filled cavity within the skull of vertebrates, located between the outer ear and the inner ear. The middle ear is linked to the pharynx (and therefore to the outside air) via the Eustachian tube and in mammals contains the three auditory ossicles, which transmit sound vibrations from the outer ear, via the eardrum, to the inner ear, via the oval window.
