Classify and describe epithelial tissue based on structural
modifications of cells.
Epithelial cells are divided into two broad categories based on structural modification of the cells:
(A) Simple Epithelium and
(B) Compound (Stratified) Epithelium
Simple Epithelium: It is the epithelium tissue which has a single layer of the cell. It is further divided into three: Squamous cells, cuboidal cells and columnar epithelium.
Compound (stratified) Epithelium: It is the epithelium tissue which has two or more layers of cells lined together.
