Transcript

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