What does the acronym CNS stand for?

• A. Central nervous system
• B. Cardiac nervous system
• C. Central neural system
• D. Cranial nervous system

Answer: (A)

Central nervous system stands for the central nervous system. It is the brain and spinal cord—the main processing and command center of the nervous system that integrates sensory information, makes decisions, and coordinates motor actions. It’s distinct from the peripheral nervous system, which includes all the nerves outside the brain and spinal cord. The other terms aren’t standard: a cardiac nervous system would imply nerves that regulate the heart, central neural system isn’t a recognized term, and cranial nervous system would incorrectly emphasize the skull and cranial nerves, which are actually part of the peripheral nervous system.
