Next to the middle ear in the bone of the skull is a small compartment which contains the hearing and balance apparatus known as the inner ear.
What causes pain in the middle ear?
Middle Ear Infection A cold, allergies, or a sinus infection can block the tubes in your middle ear. When fluid builds up and gets infected, your doctor will call it otitis media. This is the most common cause of ear pain.
What are the 3 functions of the middle ear?
It is classical to ascribe three functions to the middle ear: the transmission of acoustic vibrations from the tympanic membrane to the cochlea, impedance matching between the air in the external auditary meatus and the labyrinthine fluids, and protection of the inner ear by means of the acoustic reflex.
What are the two main functions of the middle ear?
The ears are organs that provide two main functions — hearing and balance — that depend on specialized receptors called hair cells.
