Concept:The cochlea changes sound vibrations into nerve impulses that the auditory nerve carries to the brain.
Explanation:Sound waves first enter through the auditory canal and strike the eardrum.
The eardrum vibrates, and the ossicles amplify these vibrations.
The vibrations are passed into the fluid-filled cochlea in the inner ear.
Inside the cochlea, movement of fluid bends tiny hair cells.
These hair cells convert the mechanical vibrations into electrical nerve signals.
The auditory nerve then receives these signals and sends them to the brain for interpretation.
Thus, the cochlea is the structure that transmits sound information to the auditory nerve.
Answer:C. Cochlea
