Epithelial Tissue Characteristics

In this article we will discuss about the epithelial tissue characteristics

Epithelial Tissue Characteristics

• The epithelial tissue is a type of animal tissue
• Epithelial tissue forms the lining or covering of internal and external surface of the body
• Epithelial tissue consists of tightly packed cells with little intercellular space
• Epithelium either single or multiple layers
• Epithelial cells sit on fibres and polysaccharides layer is called basement membrane
• Basement membrane consist of 2 layers:- basal lamina and fibrous lamina
• It’s usually avascular tissue that means they lack a blood supply, instead they receive nutrients by diffusion from capillaries in connective tissue
• Epithelium has tightly fitted continuous layer of cells. There are specialised junctions present between the cells of the epithelium, that link individual cells called intercellular junction
• Epithelial tissue have high capability to regenerate
• On the basis of number of cell layers the epithelial tissue classified as 2 types:- Simple epithelium and compound epithelium
• Function of epithelial tissue is protection, filtration, lubrication, secretion, digestion, absorption, transportation, excretion, sensory reception and reproduction.
