Cochlea
The cochlea is a spiral-shaped,Fluid-filled structure in the inner ear essential for hearing. It converts sound vibrations from the outside environment into electrical signals that the brain can understand. When sound waves enter the ear, they cause movement in the fluid within the cochlea, stimulating tiny hair cells lining its interior. These hair cells then send signals through the auditory nerve to the brain, allowing us to perceive sounds. The cochlea plays a crucial role in our ability to hear, distinguishing different tones and volumes.
