Question: 1 / 400

What is the primary function of the cochlea?

To filter sounds

To balance fluid pressure

To encode sound vibrations

The primary function of the cochlea is to encode sound vibrations. The cochlea is a spiral-shaped, fluid-filled structure in the inner ear that plays a critical role in the process of hearing. When sound waves enter the ear, they cause the fluid within the cochlea to move. This movement stimulates hair cells located along the basilar membrane, converting the mechanical energy of sound vibrations into electrical signals. These electrical signals are then transmitted to the brain via the auditory nerve, allowing for the perception of sound.

While filtering sounds, balancing fluid pressure, and transmitting environmental sounds are important auditory and physiological processes, they are not the cochlea's primary role. The cochlea's distinct function revolves around transforming sound vibrations into a form that the brain can interpret, which is central to our ability to hear.
