and Resources Types of Hearing Loss The three main sections of
the ear: - The outer ear is the part of the ear that starts at
the pinna or auricle, extends through the external ear canal,
and ends at the eardrum. - The middle ear is the part of the ear
that begins with the eardrum at the end of the ear canal. It
includes three small bones called ossicles that move in response
to sound waves entering the ear. This movement helps to conduct
the sound into the inner ear. The middle ear also contains the
Eustachian (you-stay-shee-un) tube that helps to maintain normal
air pressure in the ear. - The inner ear contains the sensory
organ for hearing called the organ of Corti that is housed in
the cochlea (pronounced COKE-lee-uh). The part of the auditory
nerve that is located in the inner ear sends impulses from the
cochlea to the brain signaling that sound waves have entered the
ear. The inner ear also contains the organ of balance called the
labyrint
