The tissue type that lines surfaces and forms glands is called what?

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

Answer: (B)

Epithelial tissue is the type that lines surfaces and forms glands. It creates continuous sheets that cover body surfaces and line cavities, protecting underlying tissues and regulating permeability. It also gives rise to glands through inward folding of the epithelium, which then specialize to produce secretions while remaining connected to ducts lined by epithelial cells. Epithelial cells are tightly packed, have apical and basolateral surfaces, are usually avascular, and regenerate readily, all of which support their roles in lining and gland formation. This distinguishes it from connective tissue (support and filling spaces), muscle tissue (contraction), and nervous tissue (signal transmission).
