A)stratified cuboidal
B)stratified columnar
C)transitional
D)simple columnar
E)stratified squamous

Answer 2

B

Question 3

A tissue sliced on an angle to be made into a histology slide is said to be an oblique section.

Answer 3

True

Question 4

The histological sections used to make the slides we observe in the lab are usually about 10-15 cell layers thick.

Question 5

A group of cells that are alike in function and appearance is called a tissue.

Question 6

Where is the keratinized form of stratified squamous epithelium found in the body?

A)The lining of the esophagus
B)The lining of the oral cavity
C)The epidermis of the skin
D)The anal canal
E)The vagina

Question 7

The thinnest type of epithelial tissue in the body, which allows rapid diffusion of substances through the cells, is simple cuboidal epithelium.

Question 8

Glandular epithelium makes up glands such as sweat glands; it is always multicellular.

Question 9

How do epithelial cells obtain their nourishment and get rid of their waste?

A)Through small channels in the tissue
B)Through their extensive blood vessels
C)Through the air in the environment
D)Through the blood vessels of the underlying connective tissue
E)By a combination of all of these methods

Question 10

Which type of epithelial tissue is composed of only one layer of cells, but appears layered, because some of the cells do not reach the free surface?

A)Transitional
B)Stratified squamous
C)Simple columnar
D)Stratified cuboidal
E)Pseudostratified columnar

Question 11

Which type of epithelial tissue is found in the air sacs of the lungs, the walls of capillaries, and the inner linings of blood vessels?

A)Stratified squamous
B)Simple cuboidal
C)Simple columnar
D)Transitional
E)Simple squamous

B)The cells closest to the basement membrane are dividing cells.
C)It is acellular.
D)It is composed of collagen and secretions from the cells.
E)It serves to anchor the epithelial tissues to the underlying connective tissue.

Question 13

Which type of epithelial tissue provides protection against respiratory infections, due to the presence of mucus and cilia?

A)Simple squamous
B)Pseudostratified columnar
C)Stratified columnar
D)Simple cuboidal
