  1. 1. The Nervous System  By: Paige Stegne  Grade 5 Fessenden School
  2. 2. <ul><li>Important Parts of the Nervous System  </li></ul><ul><li>spinal Cord </li></ul><ul><li>brain </li></ul><ul><li>facial Nerves </li></ul><ul><li>sciatic Nerves </li></ul><ul><li>sensory Nerves </li></ul><ul><li>mixed Nerves </li></ul><ul><li>motor Nerves </li></ul>
  3. 3. The Spinal Cord  <ul><li>structure: made of a bundle of nerve fibres (called axons) </li></ul><ul><li>function: basically the information highway of the human body </li></ul><ul><li>messages are sent back and forth to the brain and other parts of the body </li></ul><ul><li>info: includes touch, temperature, joint position and signals telling muscles to move </li></ul>
  4. 4. The Brain  <ul><li>structure: pink, jelly-like substance folded over itself to maximize its surface area </li></ul><ul><li>function: controls everything in your body </li></ul><ul><li>cells in the brain control heart rate, body temperature and respiration </li></ul><ul><li>hormone control of the renal glands, thyroid, reproductive organs and kidneys </li></ul>
  5. 5. Sciatic Nerves  <ul><li>branches of the Lumbar nerves </li></ul><ul><li>longest and largest nerves in the human body </li></ul><ul><li>supply nerve impulses to the muscles and skin in hip joints, thighs, feet, lower legs and most of the skin below the knee </li></ul>
  6. 6. Facial nerves  <ul><li>the seventh cranial nerve </li></ul><ul><li>begins in the spinal cord </li></ul><ul><li>branches into the face, neck, outer ear, and salivary glands </li></ul><ul><li>performs both motor and sensory functions </li></ul><ul><li>branches from the brain stem up </li></ul><ul><li>divides into smaller nerves to reach the face, neck, salivary glands and outer ear </li></ul><ul><li>controls the muscles of the neck, facial expressions, and muscles on the forehead </li></ul><ul><li>reports taste from front 23 of the tongue </li></ul><ul><li>carries sensations from the outer ear </li></ul>
  7. 7. Relationships with other body systems  <ul><li>relates to the muscular system and the skeletal system </li></ul><ul><li>skull protects the brain </li></ul><ul><li>spine protects the spinal cord </li></ul><ul><li>nerves send messages to the muscles to tell you if something is wrong or hurt </li></ul><ul><li>in the cardiovascular system , the nervous system modulates heart rate, contractile strength and vascular tone </li></ul>
  8. 8. Healthy Effects  <ul><li>have healthy fats with vitamins D and B12 </li></ul><ul><li>vitamin B </li></ul><ul><li>potassium </li></ul><ul><li>sodium ions </li></ul><ul><li>practise writing everyday to exercise motor and sensory neurons in your brain </li></ul><ul><li>eat tomatoes, carrots, peppers and leafy green vegetables </li></ul>
  9. 9. Harmful Effects  <ul><li>alcohol =BAD </li></ul><ul><li>drugs =BAD </li></ul><ul><li>tobacco = BAD </li></ul><ul><li>smoking =BAD </li></ul><ul><li>these mess with your brain </li></ul><ul><li>these things are NOT good for the nervous system </li></ul>
  10. 10. Diseases of the Nervous System  <ul><li>spinal tumors: </li></ul><ul><li>tumors that involve the spinal cord or vertebral column </li></ul><ul><li>can either be primary or secondary </li></ul><ul><li>primary: originating from the spinal cord </li></ul><ul><li>secondary : spreading to the spinal cord from other parts of the body </li></ul><ul><li>can cause cases of a metastatic cancer </li></ul><ul><li>epilepsy: </li></ul><ul><li>a condition characterized by recurring seizures </li></ul><ul><li>seizures are abnormal over activity of the cells in the brain which affect variable regions of the central nervous system; mostly forebrain </li></ul><ul><li>any injury to the brain can lead to seizures and sometimes epilepsy </li></ul>
  11. 11. The most Interesting facts about the Nervous System  <ul><li>divided into 2 parts- central nervous system and the peripheral nervous system  </li></ul><ul><li>nerves can pass messages in less than a fraction of a second  </li></ul><ul><li>there are MILLIONS of nerve cells in the human body  </li></ul><ul><li>the brain alone has about 100 million neurons , which lined up would make a 600 mile-long line  </li></ul><ul><li>thirty-one pairs of nerves of nerves originate from the spinal cord  </li></ul><ul><li>in humans , the right side of the brain controls the left side of the body, and vice versa  </li></ul>
  12. 12. Even MORE Interesting Facts  <ul><li>the weight of the brain in an average adult female is 1275 grams  </li></ul><ul><li>the brain looks like a giant , wrinkled walnut  </li></ul><ul><li>the weight of the brain in an average adult male is 1375 grams  </li></ul>
  13. 13. My References  <ul><li>www.innerbody.com </li></ul><ul><li>www.answers.com </li></ul><ul><li>www.buzzle.com </li></ul><ul><li>www.nervoussystemdieseases.com </li></ul><ul><li>www.wikipedia.org </li></ul><ul><li>The Human Body by S. Bruno </li></ul>
