Which letter on the diagram indicates motile structural elements of the epithelial membrane. Epithelial tissue has several uses including absorption of materials protection from foreign sources providing a sense of touch secreting bodily fluids and transporting materials between cells. C a basal lamina plus a layer of reticular fibers equals a basement membrane. D only the basal lamina can be seen by light microscopy.

Leave a reply cancel reply. The difference between a basal lamina and a basement membrane is that a the basal lamina is thicker. Base your answers to questions 26 and 27 on the two sets of cell organelles in the chart below and on your knowledge of biology.
