Fig. 12. Bowman's layer of the human cornea. Stromal collagen fibers (S) insert into the posterior aspect of Bowman's layer (B). The anterior aspect of Bowman's layer appears smooth but slightly irregular. The lamina densa appears as a continuous, dense band adjacent to numerous hemidesinosomes along the basal epithelium (E). Bar = 2 μm. (Courtesy of Roger Beuerman, Ph.D., New Orleans, Louisiana.)
