Question

3.1 Epithelial cells can be classified in two ways. Name these two ways and the different types for each way?

Answer 1

$$solution$$

The number of cell layers generated and the structure of the cells are used to classify epithelial tissues.

 Cell shapes can be squamous (flattened and thin), cuboidal , or columnar . Similarly, the number of cell layers in the tissue can be one(where every cell rests on the basal lamina)which is a simple epithelium, or more than one, which is a stratified epithelium and only the basal layer of cells rests on the basal lamina. Pseudostratified - describes tissue with a single layer of irregularly shaped cells that give the appearance of more than one layer. Transitional epithelium is a type of specialized stratified epithelium in which the cell shape can shift.
