Sound waves enter the outer ear through the external auditory canal, or pinna.
The waves or vibrations are funneled into the canal until they reach the tympanic membrane, or eardrum. They are named for the objects they resemble. The stapes sends the waves through the oval window to the inner ear, where the cochlea is located. The cochlea is filled with fluid. The cochlea contains the organ of Corti, which is made up of tiny hair cells.
