The function of nervous system is to coordinate the activities of our body. It is the control system for all our actions, thinking and behaviour. The nervous system helps all other systems of our body to work together. The nervous system is like a manager inside our body. Its job is to control and coordinate the parts of our body so that they work together, doing their job at the right time.
Our nervous system coordinates muscles so that we can do things which need thinking like reading, writing, cycling or dancing. The nervous system also coordinates things which we don't have to think about, like heart beat and breathing.

The human nervous system receives information from the surroundings, processes it, interprets it and then responds accordingly. The nervous system also passes information from one internal system to another. For example, as soon as we put food in our mouth, it immediately causes the release of saliva from the salivary glands.

The nervous system is the control centre of our body. It recognizes the sensations and gives instructions to the body to respond in an appropriate way. Activities like seeing, hearing, tasting, smelling, laughing, crying, reading, writing, walking, climbing, talking, feeling pain or pleasure would not be possible without the nervous system.

The brain, the spinal cord and the network of nerves form the nervous system.
