WebThese cells are so small that the approximately 18,000 cells in your cochlea could fit on the head of a pin. Stereocilia are on top of these hair cells. Stereocilia are delicate, hair-like projections that react to cochlea fluid movement. There are two kinds of hair cells — inner hair cells and outer hair cells. 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 ... how many minutes to 11:50WebRock around the clock Hair Cell.

WebThe total number of outer hair cells in the cochlea has been estimated at 12,000 and the number of inner hair cells at 3,500. Although there are about 30,000 fibres in the cochlear nerve, there is considerable overlap in the innervation of the outer hair cells. A single fibre may supply endings to many hair cells, which thus share a “party ...
