Resonance of the Basilar Membrane

Question 0

Where do higher frequency waves excite hair cells of the basilar membrane?

Answer 0

Deflect short & stiff basilar membrane fibers - NEAR THE OVAL WINDOW

Question 1

Do sound waves of low frequency affect the cochlear duct?

Answer 1

No, it travels around the apex and therefore doesn’t excite the hair cells.

Question 2

Where do mid-low frequency waves excite hair cells of the basilar membrane?

Answer 2

Deflect longer basilar membrane fibers - FURTHER DOWN THE COCHLEA (closer to the apex).
