The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
What are two examples of the nervous system?

- The brain and the spinal cord are the central nervous system.
- The nerves that go through the whole body make up the peripheral nervous system.
What is an example of a nervous system cell?
Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.
How does the nervous system work simple answer?

What is the main function of the nervous system and how is it structured?
The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
Why is the nervous system the most important body system?
The human nervous system is responsible for coordinating every movement and action your body makes. More importantly, it controls every function inside the human body as well. For your heart to beat, your lungs to breath, and your feet to walk, your nervous system must be functioning properly.
