Factors including exposure, background and geographic of that person could produce varying results. It must be used with immersion oil and we wont have students doing that. -Epithelial tissues typically have cells with a basal surface that is attached to an apical membrane that attaches epithelial cells to underlying tissues. What are the three types of muscular tissue? A layer of epithelial cells always serves as an outer layer for some structure, but, when looking at a tissue preparation on a slide, do not assume that just because you have found one end of the tissue sample you are automatically looking at epithelial tissue. RightFigure 5-4. Why do you think that is? Which type(s) of epithelial cells have a basal lamina? If this experiment were performed on a friend I believe that the results would vary. 13. Similarities: All layers are made up of epithelial cells, All layers are tightly packed, There are no blood vessels, All layers but the stratum basale layer contain keratin. , A couple of advantages of having greater distribution of touch receptors in higher sensitive, 3. 5. 3.
