Verified
Vibration of the ________ causes the hair cells of the cochlea to vibrate.
A) scala tympani
B) scala vestibule
C) basilar membrane
D) tectorial membrane
Scala Tympani
A coiled, fluid-filled tube within the inner ear, part of the cochlea, that transmits sound vibrations to the auditory nerve.
Basilar Membrane
A structure in the cochlea of the inner ear that plays a key role in the sense of hearing by vibrating in response to sound.
Tectorial Membrane
A structure located within the spine that provides stability by connecting the atlas to the axis, which are the first two cervical vertebrae.
- Acquire knowledge on the structure and purpose of the ear's components, such as the tympanic membrane, cochlea, and auditory ossicles.
- Acquire knowledge on how the organ of Corti functions in the processing and perception of sound.

Final Answer :
C
Explanation :
The basilar membrane contains the hair cells of the cochlea, which are responsible for transducing sound waves into electrical signals that can be interpreted by the brain. As the fluid-filled cochlea vibrates in response to sound waves, the basilar membrane vibrates, causing the hair cells to bend and generate electrical signals.
