What's the Nervous System? (for Kids)? ›

The nervous system includes the brain, spinal cord, and a complex network of nerves. This system sends messages back and forth between the brain and the body. The brain is what controls all the body's functions.

The nervous system transmits signals between the brain and the rest of the body, including internal organs. In this way, the nervous system's activity controls the ability to move, breathe, see, think, and more. The basic unit of the nervous system is a nerve cell, or neuron.

The signal transmission occurs at 260 to 268 miles per hour. The slowest signal transmission in the human body occurs within the skin. It is the largest organ of the body and sense organs, which transmit signals at 1 mile per hour. The human nervous system starts to shrink as we grow older.

Your nervous system controls everything you do, including breathing, walking, thinking, and feeling. The nervous system is made up of your brain, spinal cord, and billions of nerves throughout your body. These nerves are like tiny wires that run through your whole body to send messages to and from the brain.

The nervous system includes the brain, nerves and spinal cord. It is the communication center for the body, sending and receiving messages, regulating body functions and serving as the control center for the five senses and for emotions, speech, coordination, balance, and learning.

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.

Nervous System Regulation is what allows us to shift flexibly between different nervous system states in response to internal and external stressors. A balanced nervous system can “spring back” easily in response to stress just like a rubber band.

It includes the brain, spinal cord, and nerve cells, also called neurons. The structure of the nervous system allows it to take in information through the senses, process the information, and then produce a reaction, such as making your muscles move or causing you to feel pain.

The nervous system is made up of the brain, spinal cord, and nerves. These parts work together to allow your child to think, learn, speak, and feel emotions. They also help to control basic body functions, such as movement, sensation, breathing, and heartbeat.
