  1. What cranial nerve innervates the ciliary ganglion?
    oculomotor nerve
  2. What is the physical action associated with the ciliary ganglion?
    pupil restriction
  3. What body structure(s) is innervated via the ciliary gland?
    the eye muscles
  4. What cranial nerve innervates the pterygopalatine ganglion?
    the facial nerve
  5. What body structure(s) are innervated via the pterygopalatine ganglion?
    nasal and lacrimal glands
  6. What physical response is associated with the pterygopalatine ganglion?
    eye watering and nasal secretions
  7. What cranial nerve innervates the submandibular ganglion?
    the facial nerve
  8. What body structure(s) are innervated via the submandibular ganglion?
    salivary glands
  9. What physical response is associated with the submandibular ganglion?
    increased saliva production
  10. What cranial nerve innervates the otic ganglion?
    the glossopharyngeal nerve
  11. What body structure(s) is innervated via the otic ganglion?
    the parotid salivary glands
  12. What physical response is associated with the otic ganglion?
    increased saliva production
  13. The parasympathetic innervation of the thoracic and abdominal cavities is through the:
    vagus nerve
  14. Will the innervation of the thoracic cavity, via the vagus nerve, have an inhibitory or excitatory effect?
    inhibitory
  15. What kind of effect will vagus nerve innervation have on the addominal cavity?
    excitatory
  16. Innervation through the sacral spinal cord stimulates the:
    pelvic cavity
  17. List two physical responses to innervation of the pelvic cavity via the sacral spinal cord.
    • urine activity
    • increased blood flow to the reproductive system
  18. Which type of drug will bind to a receptor site and have the opposite effect of a neurotransmitter?
    antagonist
  19. Which type of drug will bind to a receptor and mimic the effect of a neurotransmitter?
    agonist
  20. Which type of drug will bind to a receptor site and prevent a neurotransmitter from binding?
    blocker
  21. The neurotransmitter released by parasympathetic preganglionic and postganglionic fibers is:
    acetylcholine
  22. What type of receptor is on the parasympathetic postganglionic neuron?
    nicotinic receptor
  23. What happens when acetylcholine binds to a nicotinic receptor?
    sodium channels open causing the postganglionic neuron to depolarize
  24. What class of receptor is on the target tissue in the parasympathetic division?
    muscarinic receptor
  25. What does the muscarinic receptor effect?
    potassium permeability
  26. If potassium leaves the target tissue it will begin to:
    repolarize
  27. Plant toxins, such as those in the deadly nightshade mushroom, can bind to which type of receptor?
    muscarinic
  28. List the four things in the body that are constricted or decreased when under the control of the parasympathetic division.
    • constriction of airways
    • constriction of pupils
    • decreased metabolic rate
    • decreased HR and BP
  29. List the five things/functions of the human body that are increased while under the control of the parasympathetic division of the ANS.
    • increased smooth muscle contraction
    • increased urinary activity
    • increased blood flow to the reproductive system
    • increase in nutrient absorption
    • increase in secretion from the digestive glands
