Question

Sound waves induce movements of the hair cells of the organ of Corti via?

1) movement of the basilar membrane relative to the tectorial membrane
2) movement of the scala tympani
3) movement of the malleus against the round window
4) movement of the stapes against the round window
5) contraction of the muscle fibers within the middle ear

Answer 1

Sound waves induce movements of the hair cells of the organ of Corti via movement of the basilar membrane relative to the tectorial membrane.

Step-by-step explanation:

Sound waves induce movements of the hair cells of the organ of Corti via movement of the basilar membrane relative to the tectorial membrane. When sound waves enter the inner ear, they cause the basilar membrane to vibrate, which in turn stimulates the hair cells. The movement of the hair cells creates electrical signals that are sent to the brain, allowing us to perceive sound.
