- The middle ear interacts with the pharynx, adjusts to changes in pressure outside, and transfers vibrations from the eardrum to the inner ear.
- The small passageway, also known as the auditory tube or eustachian tube, that runs from the middle ear to the nasopharynx.
- Pressure is equalized on both sides of the tympanic membrane via the tube (eardrum).
- The inner ear membrane in the fenestra ovalis receives sound waves from the incus through the stapes.
