How hearing works
The inner ear plays two major roles; transmit sound to the brain and ensure the body balance. This part comprises, among other ear, the cochlea, a snail-type which includes sensory cells. These cells move under the influence of the movement of liquid endolymph and perilymph. These cells are often the cause of hearing loss, in fact 90 to 95% of deaf people have damaged or dead cells in the cochlea. In short, the sound is picked up by the sensory cells in the cochlea, and then be converted into nerve impulses in order to get to the brain.
The balance, as mentioned earlier, we also ensured by the inner ear. In fact, three miniature canals filled with endolymphatic fluid that informs the body of its spatial position. For example, if you turn quickly on you, and you stop altogether, the head continues to turn to. The cause of the dizziness is the continuous movement of the liquid in the channels. In fact some people have a condition called “Meniere’s disease”, which comes from a dysfunction of the inner ear.
