Hair stereocili

WebThe hair bundle movement is the name of this motion. The stereocilia move up and down when sound waves enter the cochlea. The stereocilia's tips have ion channels that are opened and closed by this action. Ions enter the IHCs when the ion channels are open, which causes the IHCs to generate electrical impulses. The brain then processes these ... WebStereocilia mediate transduction in vertebrate hair cells (auditory system/cilium/vestibular system) The vertebrate hair cell is a sensory receptor that responds to mechanical stimulation of its hair bundle, which usually consists of numerous large microvilli (stereocilia) and a single true cilium (the kinocilium).
