How many tissue types are listed as the four basic tissue types?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (C)

Four tissue types are recognized in this framework: epithelial, connective, muscle, and nervous. Each type has distinct roles and characteristics that together cover all tissues in the body. Epithelial tissue lines surfaces and forms glands, providing protection and enabling absorption and secretion. Connective tissue supports, binds, and stores energy, with examples like bone, cartilage, blood, and fat. Muscle tissue contracts to produce movement, including skeletal, cardiac, and smooth muscle. Nervous tissue transmits electrical signals and coordinates activities throughout the body. Because these four categories encompass all the basic tissue types taught in introductory anatomy, the number listed as the four basic tissue types is four.
