Nervous tissue is best described as which?

• A. Move the body
• B. Attach to bones
• C. Detect stimuli, process information
• D. Contract for movement

Answer: (C)

Nervous tissue is specialized for sensing the body's environment and for processing and transmitting information. Neurons detect stimuli through receptors and generate electrical signals that travel to the brain or spinal cord, where those signals are interpreted and integrated. This rapid signaling system coordinates responses, from reflexes to complex thoughts and memories. This function is distinct from other tissues: muscle tissue contracts to move the body, connective tissue provides support and connection, and epithelial tissue lines surfaces and forms barriers. So the description that nervous tissue detects stimuli and processes information best captures its main role in sensing and interpreting signals.
