Parts of The Nervous system

The nervous system is one of the most important parts of the human body. In fact, without it, you wouldn't be able to be reading this right now! The nervous system has 3 parts to it, the spinal cord (that's what is holding you up right now), the brain (the big cheese and or head honcho of the body), and millions of tiny nerves that develop your sense of touch. Even though the nervous system is very strong, there are many diseases that can affect the nervous system including: brain tumors , bipolar disorder, Alzheimer's disease , Parkinson's disease , Huntington's disease, fragile X syndrome and spinocerebellar atrophy. The brain and nervous system form an intricate network of electrical signals that are responsible for coordinating muscles, the senses, speech, memories, thought and emotion. The brain sends messages to your nerves telling them to move your arm up, or stomp your foot. Your nerves are very thin, the longest ones stretch up to three feet long!
