웹The electron microscope shows two components to basement membranes, a clear or electron lucent layer next to the basal surfaces of the cells and a dark or electron-dense layer beneath this. These layers are called the lamina lucida and the … The layers of the basal lamina ("BL") and those of the basement membrane ("BM") are described below: Anchoring fibrils composed of type VII collagen extend from the basal lamina into the underlying reticular lamina and loop around collagen bundles. Although found beneath all basal laminae, they are especially numerous in stratified squamous cells of the skin.
