Hearing and Balance
Both hearing and balance occur within the ear. In hearing, sound waves pass from the outer ear into the auditory canal. They strike the ear drum making it vibrate. These vibrations travel to the middle ear, setting into motion three tiny bones, The hammer, anvil and stirrup. The vibrations continue thru the cochlea and deep into the inner ear which contains a fluid reservoir. As fluid ripples across mebranes it stirs tiny hairs connected to nerve endings. The stimulated nerve endings carry impulses into the brain where they are interpreted as sound. Learn More about How Hearing Works.
Also located in the inner ear is the equilibrium or balance center. The center sends continuous messages about the bodies position to the brain. This information helps us maintain balance. Learn More about How Balance Works.
