Question

• A. Muscle tissue
• B. Epithelial tissue
• C. Neural tissue
• D. None of these

Answer 1

The correct option is B

Epithelial tissue

Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the covering or lining of all internal and external body surfaces. Epithelial tissue that occurs on surfaces on the interior of the body is known as endothelium. Epithelial cells are packed tightly together, with almost no intercellular spaces and only a small amount of intercellular substance.
