EM 3: (enlargement of section from class print): The basement membrane region contains collagen fibrils and a fuzzy basal lamina that is adjacent to the plasma membrane at the basal end of the intestinal absorptive cells. Basal lamina Collagen Interdigitation of plasma membrane

EM 4: Apical end of intestinal absorptive cell with prominent brush border visible. The microvilli of the brush border are coated with a glycocalyx which appears as a fuzzy layer on the lumenal aspect of the brush border. A goblet cell occupies part of the image. Microvilli Glycocalyx Goblet cell
