The nervous system is a complex network in our bodies that controls everything we do, like thinking, feeling, and moving. It is made up of two main parts: the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which includes all the nerves that run throughout the rest of our body. The nervous system helps us react quickly to danger, feel pain, and even learn new things. Taking care of our nervous system by eating healthy foods and getting enough sleep is important for staying healthy and happy.

quick facts
- The nervous system is made up of the brain, spinal cord, and nerves.
- It controls everything we do, including breathing, walking, and thinking.
- The brain is like the command center of the nervous system, sending messages to different parts of the body.
- There are over 100 billion nerve cells in the brain alone.
- The nervous system is divided into two parts: the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves throughout the body).
card list
| Front | Back |
|---|---|
| Neuron | Neuron: A nerve cell that transmits information in the brain and nervous system. |
| Central nervous system | The central nervous system is the main control center of the body, including the brain and spinal cord. |
| Peripheral nervous system | The peripheral nervous system is the network of nerves that connect the brain and spinal cord to the rest of the body. |
| Spinal cord | The main pathway for messages between the brain and the rest of the body. |
| Brain | The brain is the control center of the body, responsible for thinking, feeling, and controlling movement. |
| Cerebellum | The cerebellum is the part of the brain that helps with coordination and balance. |
| Cerebral cortex | The outer layer of the brain responsible for thinking, feeling, and voluntary movement. |
| Axon | The axon is a long, slender projection of a nerve cell that carries electrical signals away from the cell body. |
| Dendrite | A dendrite is a branch-like structure on a nerve cell that receives information from other cells. |
| Synapse | A synapse is a small gap between two nerve cells where they communicate with each other. |
| Neurotransmitter | Chemical messenger that transmits signals between neurons in the brain and nervous system. |
| Nerve impulse | Signal that travels along a nerve cell. |
| Myelin sheath | Protective covering around nerve cells that helps speed up electrical signals. |
| Reflex | Reflex: A quick automatic response to a stimulus without needing to think about it. |
| Autonomic nervous system | Controls involuntary actions in the body. |
| Sympathetic nervous system | Part of the nervous system that controls the body’s fight or flight response. |
| Parasympathetic nervous system | The part of the nervous system that helps the body relax and rest. |
| Fight or flight response | The body’s automatic reaction to danger, where it prepares to either fight or run away. |
| Brainstem | The brainstem is the part of the brain that connects the brain to the spinal cord and controls basic functions like breathing and heart rate. |
| Medulla oblongata | The medulla oblongata controls vital functions like breathing and heart rate. |
