Slide 8

How We Hear As the sound waves go through the cochlea, they make minute hair cells vibrate. These hair cells, called cilia, are connected to the sound-related nerve. At the point when the cilia vibrate they send an electric motivation sign to the cerebrum. At the point when the sign achieves the cerebrum, we listen! sound-related nerve cochlea Cilia From David J.
