Classification of Epithelial tissue with example

Definition: Epithelia tissue, or an epithelium (pleural epithelia), is a sheet of cells that covers the body surface, lines body cavities, and forms certain, and forms certain glands.

Important characteristics of epithelial tissue.

*  Consists of maximum cellular element and very little extracellular matrix. 
*  The cells are either single or multiple layers which usually lie on a basement       membrane.·         
* Avascular (absence of blood vessels).

Classify of Epithelial tissue

* Epithelium is classified by arrangement as 
* Simple, (one layer of cells) 
* Stratified, (more than one layer of cells)

Epithelum is also classified by cell shape as squamous, cuboidal, or columnar.

Table: Classification of covering epithelial-

Cell Shape	Number of cell layers
	Simple	Stratified	Pseudostratified
Squamish	Simples Squamish	Stratified squamous
Cubodal	Simple cuboidal	Stratitied cuboidal
Columnar	Simple columnar	Stratitied columnar
		Transitional	Pseudostratified Columnar
