Q) What is epitherial tissue ?
Answer : Epithelial tissue. It is a type of tissue in which the cells are arranged into a single or multilayered sheet with very little of intercellular space. The individual cells of this tissue are joined to one another by little quantities of a cementing substance composed of mucopolysaccharide. It is a viscous substance. Cells are held together by tight junctions and desmosomes. The cells rest on basement membrane. They do not have any direct blood supply but receive the nourishment from intercellular substances and from connective tissue by diffusion across basement membrane. It is always found forming continuous layer over the outer surfaces of body, organs and internal lining of cavities. Epithelial tissue is also called the epithelium.
