Cells form the body's skin, inner linings, and glands

Epithelial cells form the body's skin, inner linings, and glands. Epithelium refers to tissue, and it covers the entire bodies of organisms. Muscle cells cover the muscles, nerve cells have to do with the brain, whereas fat cells are found in the fatty tissues in your body. When it comes to the skin, epithelium is the tissue that covers it, as well as some other organs.
