Cilia hair cells
WebTight junctions between hair cells and the nearby supporting cells form a barrier between endolymph and perilymph that maintains the ionic imbalance. Figure 12.1 illustrates the process of mechanical … WebThe sensory hair cells maintain resting potential when kino-cilia and stereocilia are in an upright position (Figure 9 1 ). Movements of the stereocilia toward the kinocilium cause the sensory hair cell membrane to depolarize, resulting in an increased firing rate of the vestibular nerve fibers (Figure 9 2 ).
