What is the brain and spinal cord collectively called?

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

Answer: (A)

The brain and spinal cord together form the central nervous system. This system acts as the body's main processing and control center, interpreting sensory information, making decisions, and directing actions. The brain handles complex processing and planning, while the spinal cord serves as a rapid communication highway between the brain and the rest of the body, coordinating many reflexes as well. The nerves and ganglia outside the brain and spinal cord make up the peripheral nervous system, which includes the autonomic system (involuntary functions) and the somatic system (voluntary movements and sensory input).
