Multiple Choice

Which of the following statements is true of the basilar membrane?

The basilar membrane is located in the middle ear and helps in equalizing air pressure.

The basilar membrane is a rigid structure that does not move in response to sound vibrations.

The basilar membrane varies in stiffness and width along its length, allowing it to respond to different frequencies of sound.

The basilar membrane is responsible for transmitting sound waves directly to the auditory nerve.

Verified step by step guidance

Begin by understanding the location and function of the basilar membrane. It is part of the cochlea in the inner ear, not the middle ear.

Recognize that the basilar membrane is not a rigid structure. It is flexible and plays a crucial role in the process of hearing by moving in response to sound vibrations.

Learn that the basilar membrane varies in stiffness and width along its length. This variation allows it to respond to different frequencies of sound, with high frequencies affecting the base and low frequencies affecting the apex.

Understand that the basilar membrane does not transmit sound waves directly to the auditory nerve. Instead, it facilitates the conversion of sound waves into neural signals by interacting with hair cells.

Conclude that the correct statement about the basilar membrane is its ability to vary in stiffness and width, allowing it to respond to different frequencies of sound.
