Basement membrane
All epithelia rest on a basement membrane, which consists of two components, the basal lamina, secreted by epithelial cells, and a reticular lamina, secreted by fibroblasts in the underlying connective tissue. The basal lamina is, in turn, subdivided into lamina lucida and lamina densa. Serosa 15,000x

Simple squamous epithelial cell
All epithelia rest on a basement membrane, which consists of two components, the basal lamina, secreted by epithelial cells, and a reticular lamina, secreted by fibroblasts in the underlying connective tissue. The basal lamina is, in turn, subdivided into lamina lucida and lamina densa. Serosa 15,000x

Nucleus
