The middle ear communicates with the: <u>nasopharynx through the auditory meatus.</u>
- Since it creates the most pronounced anatomic opening between the two compartments in both animals and humans, it has long been considered that the round window membrane serves as the main pathway of communication between the middle ear and perilymph.
- 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.
