are there are any other types of epithelium tissues?

Epithelial tissue can be structurally divided into two groups depending on the number of layers of which it is composed. Epithelial tissue that is only one cell thick is known as simple epithelium. If it is two or more cells thick, it is known as stratified epithelium.

Simple epithelium can be subdivided further according to the shape and function of its cells.

1. Squamous

2. Cuboidal

3. Columnar

4. Pseudostratified

Stratified epithelium can be cuboidal, columnar or squamous in nature. They can be keratinized or transitional as well.
