What is the middle ear chamber called?

The middle ear chamber is called the tympanic cavity. It’s an air-filled space in the temporal bone just behind the eardrum that houses the auditory ossicles—the small bones that transmit sound vibrations from the eardrum to the inner ear. This cavity also contains muscles that help modulate loud sounds. It connects to the nasopharynx through the Eustachian tube, which helps equalize pressure on both sides of the eardrum. The other terms listed belong to the inner ear: the vestibule and semicircular canals are part of the balance system, and the cochlear duct sits inside the cochlea of the inner ear.
