MICROANATOMY

Detailed explanation-1: -Epithelial tissue is made up of epithelial cells. The cells can be different shapes and can be arranged in a single layer or multiple layers depending on where they are in your body and what kind of functions they have.

Detailed explanation-2: -Compound epithelium is made up of more than one layer (multi-layered) of cells and thus, has a limited role in secretion and absorption. Their main function is to provide protection against chemical and mechanical stresses.

Detailed explanation-3: -Simple epithelial tissues are generally classified by the shape of their cells. The four major classes of simple epithelium are: 1) simple squamous; 2) simple cuboidal; 3) simple columnar; and 4) pseudostratified.

Detailed explanation-4: -Stratified epithelium consists of two or more cell layers. Based on the shape of their most apical cell layer, they are further classified into squamous, cuboidal and columnar. There are also two types of specialized stratified epithelium: keratinized and transitional.
