Which system includes the brain, spinal cord, and nerves?

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

Answer: (A)

The nervous system is the system that includes the brain, spinal cord, and nerves. It plays a crucial role in coordinating and controlling body functions by transmitting signals throughout the body. The brain processes information received through sensory organs and sends out commands to the body, while the spinal cord acts as a primary pathway for information traveling to and from the brain. Nerves extend throughout the body, connecting different parts of the nervous system to the rest of the body and enabling communication between them. Other systems mentioned, such as the endocrine system, focus on hormone regulation and slower biochemical processes, rather than immediate signaling and response. The muscular system is concerned with movement and muscle function, and the digestive system is responsible for processing food and nutrient absorption. Each of these systems has distinct roles and components that differ from the functions and structure of the nervous system.
