Which type of tissue covers and lines body parts?

• A. Nervous tissue
• B. Muscle tissue
• C. Epithelial tissue
• D. Connective tissue

Answer: (C)

Epithelial tissue covers and lines body parts. It forms the outer layer of the skin and lines hollow organs and cavities, as well as ducts and glands. Its cells are tightly packed and sit on a basement membrane, and the tissue is usually avascular, getting nutrients from nearby tissues. Epithelial tissue comes in various shapes (squamous, cuboidal, columnar) and arrangements (single layer or multiple layers), which enables protection, secretion, and absorption. This is why it best fits the idea of covering and lining body surfaces, unlike nervous tissue that transmits signals, muscle tissue that contracts to move, or connective tissue that supports and binds.
