And as the pressure waves hit these hair cells, the Microville, these extensions, hair like extensions, basically vibrate and they cause the depolarization of the cell membrane and that initiates an action potential which then travels through these exons, through our cochlear nerve and eventually into the brain. Now, the last thing I want to talk about is something called the semicircular canals. So inside the person, inside each ear, we basically have three semicircular canals. And each one of these three semicircular canals basically lie along the three different axes, along the X, y and z axes. So the semicircular canal, just like the cochlea, contains its own fluid. And the fluid in a semicircular canal is known as our endolmp endolymph.
