The correct answer is **a: brain, spinal cord, and nerves; they process information and control responses.**
### Main Components of the Nervous System:
1. **Brain**: The central control unit of the nervous system, responsible for processing sensory information, coordinating movement, and overseeing most bodily functions, including thought, emotion, and memory.
2. **Spinal Cord**: A major pathway for information traveling to and from the brain. It also coordinates reflexes and carries motor commands from the brain to the body.
3. **Nerves**: These are the fibers that transmit signals between the brain, spinal cord, and the rest of the body. They allow communication between the central nervous system (CNS) and peripheral organs, muscles, and tissues.
### How They Work Together:
- **Information Processing**: The nervous system collects information from the environment through sensory organs (like eyes and ears), which send signals to the brain for interpretation.
- **Responses**: Once the brain processes this information, it sends commands back down through the spinal cord and out through the nerves to effectuate a response in the body (such as moving a muscle or adjusting internal processes).
- **Coordination**: This system also coordinates involuntary functions (like heartbeat and digestion) and complex voluntary movements (like walking or speaking).
Overall, the interplay between the brain, spinal cord, and nerves allows for intricate control of bodily functions and immediate responses to changes both internally and in the environment.
