During the hearing, the last structure to vibrate, resulting in a nerve signal to the brain, is the auditory nerve.
The nerve signal may be defined as the conduction of impulses that runs along with a nerve fiber from the axons to reach a neighboring neuron.
The process of hearing is initiated with the external projection of the ear which is known as Pinna. Then, the vibration of the sound reaches the tympanic membrane.
Then vibrations enter to middle ear which includes three tiny bones such as malleus, incus, and stapes.
At last, the vibrations reach the inner part of the ear which is known as the Cochlea. This part of the ear surrounds by auditory nerves which play a significant role in the transmission of signals to the brain.
Therefore, during the hearing, the last structure to vibrate, resulting in a nerve signal to the brain, is the Cochlea or the auditory nerve.
