  1. 4 parts of normal neuromuscular function in breathing
    • chemoreceptors
    • resp centers
    • perpheral nerves
    • resp muscles
  2. Respond to oxygen and carbon dioxide levels
    Signal the respiratory centers in the brain stem
  3. Control the rate and depth of breathing
    resp centers
  4. Conduct impulses from the respiratory centers to the respiratory muscles
    peripheral nerves
  5. chemoreceptors transmit impulses to the
    respiratory centers
  6. chemoreceptors located in the
    great vessels peripherally and in the brain stem centrally
  7. central chemoreceptors located in the
    ventral surface of the medulla
  8. impermeable layer of cells that separates the blood from the brain
    Blood Brain Barrier
  9. resp centers located in multiple areas within the
    medulla and pons in the brain stem
  10. 3 types of perpheral nerves
    • phrenic
    • intercostal
    • abdominal wall
  11. Nerves leave the spinal canal, travel through the neck and into the mediastinum, then over the pericardium, and insert into the diaphragm on either side of the heart

    C3 to C5
    phrenic nerve
  12. Arise from the spinal cord at levels T1 to T12
    Lie under each rib
    intercostal nerve
  13. Arise from the spinal cord at levels T7 to L1
    abdomincal wall nerves
  14. Diaphragm contracts → pushes down abdominal contents → pressure in the chest drops → causes air to rush in through the trachea → lungs inflate
    resp muscles
  15. Largest inspiratory muscle
  16. Used during heavy exercise in healthy persons
    Used at rest in those with compromised diaphragmatic function
    scalene muscles
  17. Used during heavy exercise in healthy persons
    Used at rest in those with compromised diaphragmatic function
    sternocleidomastoid muscles
  18. 2 expiratory muscles
    • internal intercostal muscles
    • abdominal wall muscles
  19. 5 types of nerve interruption
    • trauma
    • polio
    • amyothrophic lateral sclerosis-lou gehrigs disease-
    • guillain barre
    • ms
  20. spinal cord injury- cervical spine injury to the ____ to _____ area will lead to ____
    c1 to c3 lead to apnea
  21. phrenic injury- cervical spine injury to ___ to ____
    c3 to c5
  22. A congenital disorder of the muscles that leads to progressive muscular weakness
    muscular function
