Cilia hair cells
WebCochlear Hair Cell. Gradual loss of cochlear hair cells, atrophy of the stria vascularis, and thickening of the basement membrane may account for the impaired hearing that is commonly seen with aging. ... Despite a similar name, stereocilia are different from cilia (microtubule cytoskeleton–based structures) and contain actin cytoskeleton ... WebThe outer hair cells are located near the center of the basilar membrane where vibrations will be greatest while the basilar membrane is anchored under the inner hair cells (see Figure 5). These observations suggest that the movement of stereocilia and the resulting modulation of their ionic currents is likely to be greater for outer hair cells ...
