Tissue composed of fibers that can contract, causing movement of an organ or part of the body.

Tissue composed of fibers that can contract, causing movement of an organ or part of the body.

• A. Respiratory
• B. Criteria
• C. Run-of-the-Mill
• D. Muscle

Answer: (D)

Muscle tissue is defined by its ability to contract. Its cells are muscle fibers that shorten when stimulated, producing movement of a body part or an organ. This contractile property is unique to muscle tissue, enabling actions from moving bones to pumping blood. The other terms don’t describe a tissue type at all—respiratory refers to breathing, criteria means standards, and run-of-the-mill is just an ordinary adjective. So the term that matches the description is muscle.
