Depolarisation in hair cells of organ of coi occurs due to:
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.
Movement of basilar membrane
Movement of taller stereocilia toward the smaller ones
Influx of Na+
None of the above
