Hair Cells
Hair cells are embedded in the basilar membrane and become enlarged due to the movement of fluid inside the cochlea. Once enlarged, they send neural impulses to the brain via the auditory nerve.

Auditory Canal
Arrange the following structures of the ear in the order that a sound wave's energy travels through them, from the point it enters the ear to where it is converted into a neural signal.
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?
Basilar Membrane
Hair Cells
Frequency-Specific Hearing Loss
An individual sustains an injury that specifically damages the narrow, stiff base of the basilar membrane, located near the oval window. Based on the physical properties of this structure and how it processes sound waves, which auditory capability would be most directly affected?

Auditory Nerve (Vestibulocochlear Nerve)
A patient is diagnosed with a form of hearing loss caused by long-term exposure to loud noise, which has damaged the sensory receptor cells within their fluid-filled, snail-shaped inner ear structure. While sound vibrations are successfully transmitted through the outer and middle ear, the patient cannot perceive sounds because the necessary signals are not being generated. Which specific process is most directly impaired in this patient?
