Potassium channel is the most diverse class of ion
channels.
when the hair bundle is displaced in the direction of tallest
stereocilium , more transduction channels are opened.
which lead to entry of potassuim through transduction
channels,leads to depolarization of hair cells .
which in turn opens voltage gated calcium channels in the hair
cell membrane.
This calcium influx cause transmitter release from the basal
end of the cell onto the auditory nerve endings.
Transduction channels are non selective cation channel that are
permeable to all alkali cation and to many divalent cations., which
includes passage of potassium.
