7. How does the ear process sound? Put the steps in the correct order. (You may need to conduct some research)
 1. _____ a. The movement against the oval window causes motion in the fluid that fills the cochlea 
 2. _____ b. The impulse is then translated into sound by the brain. 
 3. _____ c. The inner end of the stapes moves in and out of the oval window at the same rate the eardrum is vibrating. 
 4. _____ d. Sound waves enter the ear and travel through the auditory canal. These waves cause vibrations in the eardrum. 
 5. _____ e. The vibration of the eardrum causes the bones in the middle ear to move back and forth. 
 6. _____ f. The movement of the fluid causes the hairs in the fluid to move. This movement stimulates the attached cell to send a tiny impulse along the auditory nerve to the brain.
