When the oval window vibrates, the vibration is relayed to the cochlea. As fluid in the cochlea ripples, the vibration, in turn, is transmitted to the:
A)basilar membrane.
B)anvil, hammer, and stirrup.
C)eardrum.
D)the hair cells in the auditory nerve.

Question

Quizplus · Accepted Answer

The oval window transmits vibrations to the fluid-filled cochlea of the ear, and the ripple in the fluid waves causes the basilar membrane to vibrate. The basilar membrane is a long thin strip of tissue that runs the length of the cochlea and contains hair cells which are responsible for converting the vibrations into electrical signals that can be transmitted to the brain via the auditory nerve.
