The main part of the middle ear is the tympanic cavity is a small space with a volume of approximately 1см3 located in the temporal bone. Here are three auditory ossicles: hammer, anvil, and stapes - they transmit sound vibrations from the outer ear to the inner at the same time reinforcing them.
The auditory ossicles - as the smallest fragments of the human skeleton, represent a chain, the transmission of vibrations. The handle of the hammer is closely merged with the eardrum, the head of the hammer connected with the anvil, and that, in turn, its long process to the stapes. The base of the stapes closes the window of the vestibule, thus connecting the inner ear.
