  1. Spinal and cranial nerves are all motor neurons that affect skeletal muscles
    FALSE
  2. Spinal and cranial nerves carry both autonomic and somatic nerve fibers
    TRUE
  3. Spinal and cranial nerves include both sympathetic and parasympathetic nerves on every branch?
    FALSE
  4. Spinal and cranial nerves employ a pathway that includes presynaptic and postsynaptic nerurons?
    TRUE
  5. Pupil of eye Sympathetic NS & Parasympathetic NS
    • Sypathetic: dialate
    • Parasympathetic: constrict
  6. Blood Glucose Sympathetic NS and Parasympathetic NS
    • Sympathetic: elevate
    • Parasypmpathetic: -
  7. Urinary function Sympathetic NS and Parasympathetic NS
    • Sympathetic NS:decrease urine output
    • Parasympathetic NS: -
  8. Digestive function Sympathetic NS and Parasympathetic NS
    • Sympathetic NS: decrease activity, constricts sphincters
    • Parasympathetic NS: increase peristalsis; release of enzymes; releases sphincters
  9. Heart rate Sympathetic NS and Parasympathetic NS
    Sympathetic NS: increase rate and force coronary Parasympathetic NS: decrease rate and force coronary vesselse constrict
  10. Blood Pressure Sympathetic NS and Parasympathetic NS
    • Sympathetic NS:dialates visceral vessels; increase BP diverts blood flow to brain muscle and heart
    • Parasympathetic NS: -
  11. metabolic rate Sympathetic NS and Parasympathetic NS
    • Sympathetic NS: increases
    • Parasympathetic NS: -
  12. fats Sympathetic NS and Parasympathetic NS
    Sympathetic NS: breaks down ( mobilizes fat) Parasympathetic NS: -
  13. bronchioles Sympathetic NS and Parasympathetic NS
    • Sympathetic NS: dialate
    • Parasympathetic NS: Constricts
  14. Sweat Glands Sympathetic NS and Parasympathetic NS
    • Sympathetic NS:copious sweating
    • Parasympathetic NS: -
  15. Penis/Clitoris & Vagina Sympathetic NS and Parasympathetic NS
    Sympathetic NS: ejaculation/ mucus production Parasympathetic NS: erection (vasodilation)
  16. arrector pilli muscle Sympathetic NS and Parasympathetic NS
    • Sympathetic NS: Contracts
    • Parasympathetic NS: -
  17. The parasympathetic nervous nervous system arises from the
    Brain stem and sacral spinal cord
  18. the sypathetic nervous system arises from the
    thoracic and lumbar region
  19. what are characteristics of the neurotransmitter of the ANS
    • acetylcholine is the only neurotransmiteter of the parasympatheticNS
    • most sympathetic postganglionic axons release norepinepherine
    • most sypatheitic preganglionic axons release acetylcholine
  20. can the same organ be stimulated by both sympathetic and parasympathetic innervation?
    YES!
  21. Which levels of control DOES NOT regulate the autonomic nervous system?
    thalamus
  22. which branch of the autonomic NS has ganglia near the spinal cord, and tends to inhibit gland secretionwhile stimulating hormomal secretions of the adrenal medulla
    parasympathetic NS
  23. which of the autonomic NS has ganglia near the spinal cord and tends to inhibit gland secretionwhile stimulating hormonal secretions of the adrenal medulla
    sympathetic NS
  24. what makes cranial nerves I and II relatively unique?
    sensory only
  25. which of the cranial nerves are primarily motor?
    • III
    • IV
    • VI
    • XI
    • XII
  26. where in the human nervous system are unmyelenated fibers?
    post ganglionic autonomic nervous system
  27. which system tends to allow for normal urination and defication?
    Parasympathetic system
  28. in what way does nicotine mimic acetylcholine?
    activates acetylcholine repceptors on the postsynaptic fiber
  29. sympathetic and parasympathetic systems
    • some organs or tissues are only stimulated by sympathetic fibers
    • some organs or tissues are only stimulated by parasympathetic fibers
    • most visceral organs show antagonist actions with sympathetica and parasympathetic innervation
  30. best discription of autonomic nervous system
    sympathetic and parasympathetic nervous system
