<prompt> Depolarisation in hair cells of organ of coi occurs due to:Movement of basilar membraneMovement of taller stereocilia toward the smaller onesInflux of NaNone of the above  <response>: Depolarisation in hair cells of organ of coi occurs primarily due to movement of basilar membrane TIP LINK THEORY: When the shoer stereocilia are pushed toward the taller ones, the channel open time is increased. K, the most abundant cation in endolymph, and Ca2 enter the channel and induce depolarization. Mainly K influx in the hair cells causes depolarisation.
