उत्तर
Middle ear: It consists of a chain of three ear ossicles called Malleus (hammer), Incus (anvil), and Stapes (stirrup-the smallest bone). On receiving the vibrations from the tympanic membrane, the ear ossicles amplify the vibrations and transfer these to the cochlea.
A short Eustachian tube connects the middle ear to the pharynx. It equalizes air pressure on both sides of the eardrum.
