WHAT IS EPITHELIAL TISSUE?

An epithelium or epithelial tissue is composed of one or more layer of cells covering the external and internal surfaces of various body parts. Epithelial tissue also form glands.

Epithelial membranes are derived from all three germ layers.

CHARACTERISTICS:

Epithelial tissue usually rests on a thin mints cellular membrane composed of outer thin basal lamina consisting of mucopolysaccharides and glycoproteins and fibrous or reticular lamina consisting of collagen or reticular fibres of the underlying connective tissue.

These tissue generally lack blood vessels but still have a good power of repair after injury.

NOTE: THERE ARE VARIOUS TYPES OF EPITHELIUM SO YOU NEED TO SPECIFY WHICH CHARACTERISTICS YOU WANT TO KNOW. I GAVE A GENERAL IDEA ON THE TISSUE AS A WHOLE.

FUNCTION:

1.Protection
2.Formation of exoskeleton
3.Secretion and absorption
4.Excretion
5.Exchange of gases.
6.Sensation.
7.Conduction of fluids.
