|
|
struck by sound waves, eardrum begins to vibrate; vibrations trigger the rapid movement of 3 tiny bones (ossicular chain) sound is intensified before it reaches the oval window |
middle ear
|
|
|
sound waves passing through the oval window (a membrane) initiate a wave-like movement of fluid within the cochlea. As a result, thousands of sensory hair cells are activated and electrical signals are generated. Acoustic nerve carries signals to the brain where they are recognized as sound |
inner ear
|
|
|
external ear and ear canal |
outer ear |
|
|
eardrum and 3 very small bones |
middle ear |
|
|
cochlea and auditory nerve |
inner ear |
|
|
3 tiny bones in the middle ear that work together to amplify sound waves |
hammer, anvil, stirrup |
|
|
snail-shaped part of the ear that is filled with liquid, sound waves cause the fluid to move |
