Basilar Membrane

A key structure in the cochlea of the inner ear, which plays a crucial role in the sense of hearing by vibrating in response to sound waves.

Oval Window

A membrane-covered opening that leads from the middle ear to the vestibule of the inner ear, playing a key role in the process of hearing by transmitting sound vibrations.

Cochlea

A spiral-shaped, fluid-filled inner ear structure responsible for converting sound waves into nerve impulses to be interpreted by the brain.
