The vibration of the three ossicle bones travels through the ovoid window, which is the beginning of the inner ear. at one time the vibration passes through the oval window and touches the fluid which causes a wave within the vestibular canal in the cochlea.

The organ of corti is regain next to the fluid in the vestibular canal, which is inside the co chlea. once the hair cells receive the vibration, they release neurotransmitters.

The sensory neuron receives the neurotransmitters released by the hair cells. The axons of the sensory neurons form the auditory meat. The auditory side carries the sign of the zodiac about the sound. The auditory nerve sends the signal to a center in the brainstem, there are several nuclei in the brainstem and the nuclei carry the signal to the sum in the thalamus.
