Question 16

Where will the auditory tube drain fluid

Answer 16

nasophararyx

Question 17

Tympanic membrane function

Answer 17

divides the middle and outer ear

Question 18

How does hearing occur

Answer 18

-Sound waves vibrate tympanic membrane
-Tympanic membrane/ossicles amplify vibrations to oval window
– Vibrations cause movement of (fluid) in the cochlea
– Hairs will move in response to the movement of the fluid and stimulate the hearing receptors in the cochlea
– These receptors will change the information into an electrical signal and send the information to the brain via Cochlear portion of the Vestibulocochlear nerve
