Basal lamina
Cells of the stratum basale rest on a basal lamina, securely anchored to it by numerous hemidesmosomes into which keratin filaments insert. The basal lamina is composed of a lamina lucida and a lamina densa, which rests, in turn, on the reticular lamina of the dermis. Fibrils from lamina densa anchor the basal lamina to the reticular lamina. The basal lamina together with the reticular lamina constitute the basement membrane. 35,000x
