Is epithelial lining a tissue?
Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. Because the tissues form coverings and linings, the cells have one free surface that is not in contact with other cells. …
What type of tissue is epithelial?

How do you identify epithelial tissue?
Epithelial tissues are identified by both the number of layers and the shape of the cells in the upper layers. There are eight basic types of epithelium: six of them are identified based on both the number of cells and their shape; two of them are named by the type of cell (squamous) found in them.
What are the six types of epithelial tissue?
The number of cell layers and cell types together give rise to 6 different types of epithelial tissue. Simple squamous epithelia. Simple cuboidal epithelia. Simple columnar epithelia. Stratified squamous epithelia. Stratified cuboidal epithelia. Stratified columnar epithelia.
What are the characteristics of epithelia tissue?
Epithelial tissue, or epithelium, has the following general characteristics: Epithelium consists of closely packed, flattened cells that make up the inside or outside lining of body areas. There is little intercellular material.
