As the hair cells move up and down, tiny hair-like forecasts (referred to as stereocilia) that perch in addition to the hair cells bump versus an overlying framework and bend. Flexing reasons pore-like channels, which go to the pointers of the stereocilia, to open. When that occurs, chemicals rush right into the cell, developing an electric signal.
