Which tissue type lines body cavities and covers surfaces, including skin and mucous membranes?

• A. Nervous
• B. Epithelial
• C. Muscular
• D. Connective

Answer: (B)

Epithelial tissue forms the coverings and linings of the body. It lines body cavities and organ surfaces, and it also covers the outer layer of the skin and lines mucous membranes. This tissue type acts as a protective barrier and is involved in absorption, secretion, and filtration, depending on the location. It’s typically tightly packed and sits on a basement membrane, with no direct blood supply of its own.

Nervous tissue specializes in transmitting electrical signals; muscular tissue contracts to produce movement; connective tissue supports and connects other tissues. These roles are distinct from forming linings and coverings, which is why epithelial tissue is the correct choice.
