Definition
Located between the inner and outer
ear, the middle
ear is the third part of the human auditory mechanism. From a purely anatomical point of view, the inner ear is divided into three separate units. The first consists of the tympanic cavity. It contains both the eardrum and the ossicles. The second includes the mastoid cavities, which are often implicated in
diseases of the middle ear. The third unit consists of the Eustachian tube, which is involved in the regulation of the eardrum's pressure.
