EPITHELIAL TISSUE REVIEW

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

True

2.

A

A

B

Does A or B represent tight junctions?

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.

4.

Basement membrane

A

B

All epithelia tissue have this that separates it from the tissue below. (red arrow)

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.

Apical surface

A

B

What is the name of this side of epithelia tissue? (red arrow)

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

A

B

side A

16. Name this epithelial tissue using 2 terms.

Stratified cuboidal

13. What is the shape of the cells above?

Cuboidal

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

Transitional

22. What is the name of this epithelia tissue?

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

Stratified

Squamous

14. What is the shape of the cells above?

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

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

Stratified cuboidal

27. Give the specific name of this epithelial tissue.

Holocrine

25. What type of exocrine gland is illustrated here?

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.

Exocrine

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

23. What is the name of this epithelia tissue?

Pseudostratified

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.

Simple squamous

29. Give the specific name of this epithelial tissue.

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

EXOCRINE

Goblet cells

30. Name these specific cells (re arrows)

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

Apocrine

26. What type of exocrine gland is illustrated here?

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

32. The term for a tissue that does not have its own blood supply is
