Brain
Your brain is your body’s main control center. it controls thinking, emotions, and all the body’s activities that keep you alive. The brain looks like a soft sponge and is protected by a bony skull in the head.
Nervous System
The nervous system is made up of the brain, the spinal cord, and nerves that connect the brain and spinal cord to the rest of the body. The brain sends messages through the rest of the nervous system to tell your body what to do.
Neuron
The nervous system is made of bundles of cells called neurons. Neurons are found throughout your body. They send electrical signals that direct all of your body’s activities, including thinking, breathing, and moving. These signals travel along the length of one neuron and jump to another neuron over a gap called a synapse.
