9

The covering and lining epithelia are classified according to what 2 criteria?

1. Number of layers

2. Cell Shape

10

Define simple epithelia.

One layer of cells attached to the basement membrane.

13

How are stratified epithelia named specifically?

Named according to the cells at the apical surface of the epithelial sheet.
