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
