Which tissue type is responsible for coordinating body functions and transmitting messages?

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

Answer: (C)

The point being tested is how the body coordinates functions and communicates. Nervous tissue is designed to transmit messages and coordinate activities through specialized cells called neurons (and supportive glial cells). Neurons carry electrical impulses rapidly, allowing quick communication between the brain, spinal cord, and other body parts, which enables sensing, processing, and responding to information. Muscular tissue contracts to produce movement; epithelial tissue lines surfaces and forms glands; connective tissue provides structure and support. Because nervous tissue handles signaling and integration across the body, it is the best fit for coordinating body functions and transmitting messages.
