The flashcards below were created by user Willface on FreezingBlue Flashcards. What would you like to do?


  1. What is the sympathetic receptor affecting chronotropy, and define chronotropy.
    • Beta 1 adrenergic
    • Chronotropy is in regards to changes in heart rate
  2. What is the sympathetic receptor affecting inotropy, and define inotropy
    • Beta 1 adrenergic receptor
    • Inotropy is in regards to contractile force of the heart (INotropy squeezes IN)
  3. What is the sympathetic receptor affecting dromotropy, and define dromotropy.
    • Beta 1 adrenergic receptor
    • Dromotropy is in regards to changes in cardiac muscle conduction.
  4. What is the sympathetic receptor affecting lusitropy, and define lusitropy
    • Beta 1 adrenergic
    • Lusitropy is in regards to cardiac muscle relaxation. (remember LUSItropy makes the heart LOOSE)
  5. What is the sympathetic receptor affecting blood vessels of the skin and most organs.
    Alpha 1 adrenergic
  6. What is the sympathetic action on blood vessels of the skin and most organs?
    Constriction of blood vessels, but dilation of coronary arteries
  7. What is the sympathetic receptor affecting the pupil (specifically radial muscles)
    alpha 1 adrenergic
  8. sympathetic action on pupil (clinical term)
    mydriasis (dilation)
  9. What is the sympathetic receptor affecting ciliary muscle of eye
    Beta 2 adrenergic
  10. sympathetic action on ciliary muscle of eye
    Dilation (allows far vision)
  11. What is the sympathetic receptor affecting bronchioles
    Beta 2 adrenergic
  12. sympathetic action on bronchioles
    dilation of bronchioles
  13. What is the sympathetic receptor affecting salivation
    beta 1 adrenergic
  14. sympathetic action on salivation
    increases viscous (sludgey) salivation which slows food movement
  15. What is the sympathetic receptor affecting GI wall motility
    alpha 2 and beta 2
  16. sympathetic action on GI wall motility
    relaxes wall motility
  17. What is the sympathetic receptor affecting sweat glands
    M3 receptor (muscarinic cholinergic receptor)
  18. sympathetic action on sweat glands
    increases sweating
  19. What part of ANS controls ejaculation
    Sympathetic
  20. What postganglionic receptor is involved with ejaculation
    alpha 1 adrenergic
  21. What is the parasympathetic receptor affecting chronotropy
    M2 muscarinic cholinergic
  22. What is the parasympathetic receptor affecting dromotropy
    M2 muscarinic
  23. What is the parasympathetic receptor affecting blood vessels of the skin and most organs
    none, there's no parasympathetic affect (couple exceptions like the penis)
  24. Horner's syndrome is caused by what?
    injury to sympathetic supply to head/neck, typically from stabs/gunshot wounds, whiplash, or tumors in the lung or cervical lymph nodes
  25. What are characteristics of Horner's syndrome
    • Ipsilateral Miosis (pupil constriction on one side)
    • Ipsilateral Ptosis (drooping eyelid)
  26. what is pheochromocytoma
    tumor of adrenal medulla
  27. what does pheochromocytoma cause
    over production of epinephrine
  28. treatment for pheochromocytoma
    surgical excision of adrenal tumor
  29. What is Raynaud's Syndrome
    Overly active sympathetic stimulation in the blood vessels to the fingers and/or toes
  30. What are symptoms of Raynaud's Syndrome
    • White and cold appearance of fingers and/or toes.
    • painful fingers and/or toes
    • possible tissue necrosis
  31. Treatment for Raynaud's syndrome
    Sympathectomy of affected area
  32. What is the parasympathetic receptor affecting the pupil
    M3 muscarinic
  33. What is the parasympathetic receptor affecting ciliary muscle of eye
    M3 muscarinic
  34. What is the parasympathetic receptor affecting bronchioles
    M3 muscarinic
  35. What is the parasympathetic receptor affecting salivation
    M3 muscarinic
  36. What is the parasympathetic receptor affecting GI wall motility
    M1 muscarinic
  37. What is the parasympathetic receptor affecting sweat glands
    There is no parasympathetic receptor in sweat glands
  38. What is the parasympathetic receptor affecting the penis
    M3 muscarinic
  39. What affect does parasympathetic stimulation have on the pupil of the eye
    miosis (constriction of pupil)
  40. What affect does parasympathetic stimulation have on the ciliary muscle of the eye
    constricts for near vision
  41. What affect does parasympathetic stimulation have on bronchioles
    constricts
  42. What affect does parasympathetic stimulation have on salivation
    increases thin and watery salivation to move food more easily
  43. What affect does parasympathetic stimulation have on GI wall motility
    contracts the GI wall increasing motility
  44. What affect does parasympathetic stimulation have on sweat glands
    no effect
  45. What affect does parasympathetic stimulation have on the penis
    causes erection
