EPITHELIAL TISSUE REVIEW

1. True or False. All epithelial tissue has a limited amount of intercellular material.

A 2. Does A or B represent tight junctions? B A

5. What is the difference between a secretion and an excretion? Secretion is a product the cell makes that is used elsewhere. An excretion is a waste product that the cell must get rid of.

A 4. All epithelia tissue have this that separates it from the tissue below. (red arrow) B Basement membrane

9.All epithelia tissue is avascular. What does this mean? It has no blood supply of its own, and must get is nutrients from diffusion from blood vessels in connective tissue below it.

3. What is the name of this side of epithelia tissue? (red arrow) B Apical surface

8. Where does more mitosis occur in this epithelial tissue, side A or side B?

16. Name this epithelial tissue using 2 terms. Stratified cuboidal

13. What is the shape of the cells above? Cuboidal

Squamous, Cuboidal, Columnar 11. What are the 3 basic shapes of epithelia tissue? Squamous, Cuboidal, Columnar

17. What is the name of the cell feature that is shown here? Ciliated

22. What is the name of this epithelia tissue? Transitional

15. When there is more than one layer of epithelia cells, what is the term used to name the cells? Stratified

14. What is the shape of the cells above? Squamous

12. Which of the 3 basic shapes is illustrated below? Columnar

7. What process is shown by the red arrows? Absorption

6. What process is shown by the green arrows? Secretion

19. What is the name of the cell feature is shown here? Microvilli

Increases surface area within the same volume. 20. What is the function of the cell feature is shown here? Increases surface area within the same volume.

21. The cell shape actually found in pseudostratified tissue is __________ although it is hard to tell because it is all smashed together. Columnar

27. Give the specific name of this epithelial tissue. Stratified cuboidal

25. What type of exocrine gland is illustrated here? Holocrine

10. All epithelia tissue has great mitotic capability 10. All epithelia tissue has great mitotic capability. What does this mean? It undergoes cell division quite often, and is always replacing worn and sloughed off cells.

24. What type of glands retain ducts to body surfaces? Exocrine

23. What is the name of this epithelia tissue? Pseudostratified

The cilia beat back and forth to move items past the cells. 18. What is the specific function of this cell feature in our bodies? The cilia beat back and forth to move items past the cells.

Keratinized stratified squamous 28. Give the specific name of this epithelial tissue. Keratinized stratified squamous

29. Give the specific name of this epithelial tissue. Simple squamous

EXOCRINE 31. Does this represent an exocrine gland or an endocrine gland?

30. Name these specific cells (re arrows) Goblet cells

33. What is the rule when naming a tissue as shown here? Use the shape of the most cells having the apical surface pointing toward the lumen. Here is would be cuboidal.

36. What do goblet cells secrete? mucus

26. What type of exocrine gland is illustrated here? Apocrine

35. What is so unique about transitional epithelium tissue? The ability to stretch from a multi-layered tissue to a tissue with very few layers.

Non-keratinized Stratified Squamous Epithelia

34. Name this part of the tissue outlined in yellow. Keratin
