Cochlea
The cochlea contains fluid that moves when the stapes presses against its oval window. This fluid movement leads to the enlargement of hair cells embedded in the basilar membrane.

Diagnosing Sensory Deficits
In the process of hearing, vibrations travel from the air-filled middle ear, through a chain of small bones, and must be transferred into the fluid-filled inner ear. What is the critical role of the membrane-covered opening where the last bone connects to this fluid-filled structure?
Sound energy is transmitted from the air-filled middle ear to the fluid-filled inner ear. A series of small bones conveys vibrations to a small, membrane-covered opening leading to the inner ear. What is the primary functional challenge this opening and its membrane must overcome, and how does it accomplish this?

Hair Cells
An individual is diagnosed with a form of hearing loss where sound waves are effectively collected by the outer ear and amplified by the bones of the middle ear. However, the mechanical energy from these vibrations is not being converted into the electrical signals that the brain can interpret. This specific failure in the conversion process points to a problem within which of the following structures?
