- avascular ( contain no blood vessels, get nutrition by diffusion)
- has nervous innervation
- each epithelial cell has one apical surface, two lateral surfaces and one basal surface
- basal surface of it rest on a basement membrane (a layer form by collagen fibril, and protein, carbohydrate combination)
- if basement membrane is intact the epithelial cells grown normally
- cells of epithelial tissue tightly bind with each other by junctional complex
- apical surface of epithelial cells modify and formed microvilli, cilia, stereocilia etc.
- there are many functions of epithelium : absorption, secretion, diffusion etc
