What is the Nervous System?
The nervous system is the body's information gatherer, storage center and control system. Its primary function is to collect information about the external conditions in relation to the body's external state, to analyze this information, and to initiate appropriate responses to satisfy certain needs; the most significant of these needs is survival.
The nervous system is made up of nerves, the brain, and the spinal cord. The nerves themselves do not form one single system, but several which are interrelated. Some of these are physically separate while others are different from one another in function only.
Brain- The brain is the command center of your entire body. The brain is the body's main information center. It is made of billions of neurons. The brain helps the body respond to the information it receives from the senses. The brain also processes thoughts. When you think, neurons in your brain are working.
Spinal Cord-The spinal cord is a tube of neurons that runs up the spine and attaches to the brain stem. Information from nerves that branch out to the rest of the body goes to the spinal cord.
Neurons-he cells that make up the nervous system are called neurons. Long, stringy neurons are perfect for carrying the electrical messages that are the "language" of the nervous system.
