Central nervous system
The brain and the spinal cord together.
Where it all arrives
Messages come in from the eyes, ears, skin and many other parts of the body. Something has to receive them and put them together.
Which two parts of the body do this work as the central nervous system?
What this lesson covers
The idea
The brain and spinal cord form the central nervous system, which receives information from all parts of the body and integrates it; the brain is the main coordinating centre of the body.

Centre of control
Information comes in from all parts of the body. The brain and spinal cord together receive it and integrate it. The brain is where the complex thinking is concentrated.
The brain and spinal cord form the central nervous system. It receives information from all parts of the body and integrates it. The brain is the main coordinating centre of the body.

What does the central nervous system do with information from all parts of the body?
- The cranial nerves and the spinal nerves. Those nerves form the peripheral nervous system, which carries communication between the central nervous system and the body.
- The brain and the muscles. Muscles do the final job of movement. The central nervous system is the brain and the spinal cord.
- The brain and the spinal cord — correct. Yes!
- The brain — correct. Yes!
- The spinal cord. The spinal cord is made of nerves that supply information to think about. The brain is the main coordinating centre.
- A muscle. Muscles carry out actions. The brain is the main coordinating centre.
- It detects the information, like a receptor. Receptors in sense organs detect information. The central nervous system receives and integrates it.
- It receives the information and integrates it — correct. Yes!
- It turns the information into hormones. The central nervous system works by receiving and integrating information, not by making hormones.
