Which of the Following Moves in Response to the Vibration

Question

Which of the following moves in response to the vibration of the stapes?
A) Tympanic membrane
B) Oval window
C) Malleus
D) Hammer

Accepted Answer

The stapes is the last of the three small bones in the middle ear that help to transmit sound vibrations from the eardrum to the inner ear. When the stapes moves in response to a sound wave, it pushes and pulls on the oval window, which is the membrane that separates the middle ear from the inner ear. This movement of the oval window helps to transmit the sound vibrations to the fluid-filled cochlea of the inner ear, where they can be interpreted as sound by the hair cells. The other options (A, C, D) are also part of the middle ear but are not directly involved in responding to the vibration of the stapes.
