Quizplus · Accepted Answer

The eustachian tube, also known as the auditory tube, connects the middle ear to the nasopharynx, allowing for equalization of pressure on both sides of the tympanic membrane. The pinna is the outer part of the ear that collects sound waves. The membranous and bony labyrinth are parts of the inner ear involved in balance and hearing. The auditory meatus is the canal leading to the eardrum.
