Answer 4

Simple

Question 5

What type of tissue covers body surfaces and lines body cavities?

Answer 5

Epithelial

Question 6

An epithelium consisting of one layer of cells is classified as _______, and an epithelium consisting of multiple layers is classified as ______.

Answer 6

1) Simple

2) Stratified

Question 7

What are the functions of epithelial tissue?

Answer 7

1) Secretion of substances

2) Act as a barrier

Question 8

The number of cell layers and the shape of the superficial cells are two criteria used to classify
tissue.

Answer 8

Epithelial

Question 9

The epithelium consisting of one layer of cells in which all cells rest directly on the basement membrane, but appear to be arranged in layers, is
_______ epithelium.

Answer 9

Simple (or pseudostratified)

Question 10

True or false: Pseudostratified epithelial tissue consists of many cell layers, therefore it is considered a stratified epithelium.

Answer 10

False
(Pseudostratified epithelium consists of tall columnar cells and shorter basal cells. All cells resting on the basement membrane creating a false appearance of stratification. This is simple epithelium (one layer). Notice that all of the cells contact the basement membrane and extend to the free surface.)

The type of epithelium, a single layer with both tall and short columnar cells reaching the apical surface and shorter basal cells, is called _______.

Answer 11

Pseudostratified columnar epithelium

Question 12

The epithelial type that has both tall and short columnar cells, where not all reach the free surface, thus creating a false appearance of stratification, is _______ columnar epithelium.

Answer 12

Pseudostratified

Question 13

An epithelial cell whose the height and width are about equal, is referred to as being _____ in shape.

Answer 13

Cuboidal

What is the cellular shape called in which the height and width are about equal?

Answer 14

Cuboidal

Question 15

Cells that have a square or round shape are classified as ______.

Answer 15

Cuboidal

Question 16

What structures are lined by pseudostratified columnar epithelium?

Answer 23

1) Respiratory tract from the nasal cavity to the bronchi

2) Auditory tubes

Question 24

Indicate the type of epithelium that is best suited for allowing diffusion of substances, as would be found lining the air sacs of the lungs.

Answer 24

Simple squamous
