Middle ear

The middle ear (latin: auris media) includes the tympanic cavity and the auditory tube that connects the tympanic cavity with the pharynx. The middle ear is the part of the ear between the tympanic membrane, separating it from the external ear, and the oval window of the inner ear.

The tympanic cavity of the middle ear houses three tiny bones, the auditory ossicles, which transfer the vibrations of the tympanic membrane into the waves in the fluid and membranes of the inner ear. Thus, the middle ear is responsible for transferring the compression waves generated in the air into the fluid-membrane waves within the cochlea of the inner ear.
