Hair-cell density (A), ratio between the numbers of type I and type II hair cells (B), and epithelial height (C) are plotted against a normalized distance from the center (0) to the edge (1) of the neuroepithelium along its transverse (filled circles) and longitudinal (open circles) axes. Circles, means; bars, SE. Zonal abbreviations as in Figure 3.
