The flashcards below were created by user sthomp88 on FreezingBlue Flashcards. What would you like to do?


  1. The ___________ functions to conserve energy and promote rest and digestion including: reducing heart rate, increasing GI activity for digestion and absorption, and increasing excretion
    parasympathetic nervous system
  2. The ________ mobilizes energy resources in an emergency as part of the stress response, often referred to as the fight or flight system; functions involve increasing blood sugar, heart rate, and blood pressure, and dilating bronchioles to accommodate for increased respiration
    sympathetic nervous system
  3. true or false. ALL cholinergic responses are activiated by the muscarinic receptor
    true
  4. What is the cholinergic response of the radial muscle iris (eye)?
    contraction (miosis) - the pupil gets smaller
  5. What is the cholinergic response of the sphincter muscle iris (eye)?
    contraction (near vision)
  6. What is the cholinergic response of the SA node/Atria (heart)?
    decrease in contractility increase in conduction velocity
  7. What is the cholinergic response of the vagal nerve (heart)?
    decrease in heart rate (bradycardia)
  8. What is the cholinergic response of the coronary blood vessel?
    dilation
  9. What is the cholinergic response of the skin and mucosa blood vessels?
    dilation
  10. What is the cholinergic response of the salivary gland blood vessels?
    dilation
  11. What is the cholinergic response of the bronchial muscle (lung)
    contraction
  12. What is the cholinergic response of the motility of the intestine?
    increased (diarrhea)
  13. What is the cholinergic response of the sphincters of the intestines?
    relaxation
  14. What is the cholinergic response of the detrusor muscle or the urinary bladder?
    contraction
  15. What is the cholinergic response of the trigone and sphincter of the urinary bladder?
    relaxation
  16. What is the cholinergic response of the sweat glands?
    generalized secretion
  17. What is the cholinergic response of the salivary glands?
    profuse, watery secretion
  18. What is the adrenergic response of the radial muscle iris (eye)? And what is the receptor of this organ?
    • contraction (mydriasis) bigger pupil
    • alpha
  19. What is the adrenergic response of the sphincter muscle iris (eye)? And what is the receptor of this organ?
    • relaxation (far vision)
    • beta-2
  20. What is the adrenergic response of the SA node/Atria of the heart? And what is the receptor of this organ?
    • increase in heart rate, increase in contractility, and conduction velocity
    • beta-1
  21. What is the adrenergic response of the coronary blood vessel? And what is the receptor for this organ?
    • constriction = alpha
    • dilation = beta-2
  22. What is the adrenergic response of the skin and mucosa blood vessels? And what is the receptor for this?
    • constriction
    • alpha
  23. What is the adrenergic response of the salivary gland blood vessels? And what is the receptor for this?
    • constriction
    • alpha
  24. What is the adrenergic response of the bronchial muscle? And what is the receptor for this?
    • relaxation
    • beta-2
  25. What is the adrenergic response of the intestine motility? And what is the receptor for this response?
    • decrease (constipation)
    • alpha, and beta-2
  26. What is the adrenergic response of the sphincters of the intestine? And what is the receptor for this response?
    • alpha
    • contraction
  27. What is the adrenergic response of the liver? ANd what is the receptor for this response?
    • glycogenolysis
    • beta
  28. What is the adrenergic response of the detrusor muscle of the urinary bladder? And what is the receptor for this response?
    • relaxation
    • beta-2
  29. What is the adrenergic response of the trigone and sphincter of the urinary bladder? And what is the receptor for this response?
    • contraction
    • alpha
  30. What is the adrenergic response of the sweat glands? And what is the receptor for this response?
    • contraction, gooseflesh
    • alpha
  31. What is the adrenergic response of the salivary glands? And what is the receptor for this response?
    • thick, viscous secretion
    • alpha
  32. true or false. adrenergic responses are usually the opposite of cholinergic responses.
    true
  33. What both alpha dna beta receptors in the SNS are activated, alpha responses are generally the ___________ of beta responses
    opposite
  34. What is doxazosin? What does it do?
    • an alpha 1 blocking cardiovascular drug used to lower blood pressure
    • It blocks alpha 1 receptors in vascular smooth muscle allowing beta effects to prevail to produce vasodilation
  35. What is atropine? And what does it do?
    • a PNS blocking agent, drug used to decrease salivary secretions
    • it blocks muscarinic receptors, allowing adrenergic effects to predominate
  36. Atropine is classified as what 3 things? Meaning it will block muscarinic receptors?
    • PNS blocking agent
    • muscarinic
    • cholinergic blocking agent
  37. The acronym SLUD describes the effects of the _________. What does it stand for?
    • parasympathetic nervous system
    • Salivation
    • Lacrimation
    • Urination
    • Defecation
  38. How does SLUD help us remember some effects of the SNS? Give examples of SNS effects?
    • because effects of the SNS are usually opposite of the PNS
    • xerostomia
    • dry eyes
    • constipation
