Classification of Tissues

Question 1

What two parts comprise the epithelia cell name?

Answer 1

1. The Cell shape
2. The number of cell layers present.

Question 2

What two ways are cell layers classified?

Answer 2

Simple: meaning single layer of cell alignment.
Stratified: meaning multiple cell layers.

Question 3

What occurs in the simple epithelia?

Answer 3

The filtration, absorption, and secretion across the thin epithelial barrier.

Question 4

Where is stratified epithelia found?

Answer 4

In areas where protection is important like high abrasion areas. (i.e. mouth and skin)

Question 5

What are the three common epithelial shapes? Describe them.

Answer 5

Squamous: scale like discs
Cuboidal: Boxlike same height and width
Columnar: Tall and column shaped

Question 6

What characteristic effects the nucleus?

Answer 6

The cell type it affects the shape.

Question 7

True or False: Simple epithelia are difficult to classify.

Answer 7

False they are visually easy to identify because you can see all cells within the single layer. Cells within the layer all share the same shape.

Question 8

What make stratified cells difficult to identify?

Answer 8

These tissues have multiple cell layers and vary cell shapes across the layers.

Question 9

How are stratified cells defined?

Answer 9

By the apical surface
or the cell shape within the top most ridge of the layers.
