Which term refers to the tissue that transmits signals and coordinates body activities?

• A. Endocrine
• B. Connective Tissue
• C. Nerve tissue
• D. Muscular Tissue

Answer: (C)

Nerve tissue is the system that transmits signals and coordinates the body's activities. It’s made up of neurons and supporting cells, with neurons carrying electrical impulses along their long extensions to communicate with other neurons, muscles, and glands. This rapid signaling forms the body’s communication network, enabling sensations, reflexes, and coordinated movements. The endocrine system, by contrast, uses hormones in the bloodstream and operates more slowly; muscular tissue contracts but doesn’t itself relay signals across the body; connective tissue provides structure and support rather than signaling. So the tissue that specifically transmits signals and coordinates activities is nerve tissue.
