  2. The Nervous system • Is made of three main parts • Brain • Spinal Cord • Nerves

  3. 1. The Brain • Control Center for the body • Weights about 3 pounds • Is the size a grapefruit • Has 3 main parts • Cerebellum • Cerebrum • Brain stem

  4. Brain: the cerebellum Cerebellum is located at the back side of head, near the back of the neck area. • Controls voluntary movement • Coordinates muscle action for • Running • Walking • Painting • Balance www.futureparadigm.org

  5. Brain: the cerebrum (The largest part of the brain, at the top) • Controls our ability • To think • To remember • To feel • To dream • Talk • Sense www.sinauer.com

  6. Brain: the brain stem • Brain stem (bottom) • Controls involuntary movement • Basic life support like • Heart beating • Lungs breathing • Eyes blink

  7. The Spinal Cord • Our spinal cord goes from the brain down the back through the vertebral column . • The spinal cord forms the main path for messages entering amd leaving our brain. www.daviddarling.info

  8. Spinal Cord (cont) The spinal cord is encased in vertebra for protection. http://static.howstuffworks.com/gif/nerve-10.gif

  9. The Nerves • The main part of the nervous system. • Nerves carry messages throughout your body: to, from, and within the brain. • Nerves are long and thin like threads. • They are bundles of wrapped nerve cell fibers, or neurons. www.AMBIENCR.com

  10. Neurons make up the nerves. www.sjhsyr.org

  11. Nerves (cont.): neurons • There are several types of neurons, depending on function. • Nerves • Sensory nerves come from the senses • Motor nerves send messages to muscles and other parts of the body from the brain in response to a sensory nerve message. www.epilepsyfoundation.org

  12. Diseases of the Nervous System • “Parkinson's disease is a slowly progressive disorder that affects movement, muscle control, and balance. Part of the disease process develops as cells are destroyed in certain parts of the brain stem, particularly the crescent-shaped cell mass known as the substantia nigra. “ • 1998-2009 HowStuffWorks, Inc. • Alzheimer disease (AD) is where the cerebral cortex and some other forebrain regions shrink. It affects more women than men. • Broca aphasia is defined by Websters Dictionary as a "loss or impairment of the power to use or comprehend words usually resulting from brain damage."
