The tissue surrounding the brain and spinal cord is part of which body system?

• A. Nervous system
• B. Circulatory system
• C. Digestive system
• D. Endocrine system

Answer: (A)

The nervous system is the system that includes the brain and spinal cord, along with the protective tissues around them. The layers that cover and cushion the brain and spinal cord—the meninges—are part of this system and help protect the central nervous system by providing support and a cushioning environment with cerebrospinal fluid. The circulatory system moves blood, the digestive system handles food breakdown, and the endocrine system manages hormone signals—none of these describe the tissue surrounding the brain and spinal cord.
