Tissues

Tissues

Epithelial, Connective, Muscular, Nervous

What are the major types of tissues in animals?

Epithelial Tissues

What are the functions of the epithelial tissues? (RASP)

Number of Cell layers, Shape of the Cell, Function

The types of Epithelial Tissues are based on what?

Simple, Pseudostratified, Stratified

What are the types of epithelial tissues based on the number of cell layers?

Simple Epithelium

made up of one layer of cells

Simple Epithelium

Its source is on the tunica mucosa of the digestive tube lining of the glands

Pseudostratified

This is made up of one layer of cells but of different heights, thus showing a stratified appearance

Pseudostratified

This source is on the inner lining of trachea

Stratified

This is made up of two or more layer of cells

Stratified

The source of this is the epidermis
