The middle ear is connected to the nasopharynx by the eustachian tubes, which serve as a channel to equalize pressure. The equalization of pressure is aided by yawning or swallowing. Swallowing does not cause the tympanic membrane to vibrate. This action does not cause the hammer to vibrate. This action also does not stabilize equilibrium.
