The system that includes the brain and spinal cord.

• A. Peripheral nervous system
• B. Central nervous system (CNS)
• C. Somatic nervous system
• D. Autonomic nervous system

Answer: (B)

The central nervous system consists of the brain and spinal cord and acts as the body's main control and processing center. These structures are enclosed in the skull and vertebral column and are protected by meninges and cerebrospinal fluid, highlighting why they together form the CNS. The CNS integrates and interprets information from the body and coordinates responses. Nerves outside the CNS make up the peripheral nervous system, linking the brain and spinal cord to the rest of the body. The peripheral system includes two major divisions: the somatic system, which handles voluntary movements and conscious sensation from the skin and muscles, and the autonomic system, which regulates involuntary functions like heart rate, digestion, and gland activity.
