Basement membrane

This electron micrograph shows the basement membrane with its two components, the basal lamina and the reticular lamina. The basal lamina is, in turn, subdivided into the lamina lucida and the lamina densa.  The reticular lamina lies beneath the basal lamina and is composed of loose connective tissue with type III collagen fibrils.  Anchoring fibrils extend from the lamina densa and loop around the type III collagen fibrils serving to attach the basal lamina to the underlying loose connective tissue of the reticular lamina. Capillary 45,000x.
