Myosin o The inner hair cells of organ of corti have 50-200 ciliated structure called stereocilia.o The top of each stereocilium is linked to the side of next adjacent higher stereocilium by means of a thin filamentous strucuture called the tip-link.o Mechanically gated ion channels are located at these attachment points on the sides of stereocilia.o Each stereocilium comprises of several actin filaments encased by a plasma membrane.o The opening and closing of the ion channels is accomplished through the binding and unbinding of proteins at terminal ends of the tip links with a group of channel motor proteins (myosin) which move up and down the actin filaments of stereocilia.", 'role': 'assistant'}]
