  1. Sympathetic affect on the eye?
    Pupillary Dilation (Mydriasis), α1

    ↑ ciliary aqueous humor production, β2
  2. Parasympathetic affect on the eye?
    Pupillary Constriction (Miosis), muscarinic

    Contraction of ciliary muscle (Accommodation for near vision), muscarinic
  3. Sympathetic affect on the heart?
    ↑ Rate, β1, β2

    ↑↑ Contractility, β1, β2

    ↑ Automaticity, β1, β2

    ↑ Conduction Velocity, β1, β2
  4. Parasympathetic affect on the heart?
    ↓↓ Rate, muscarinic

    ↓ Contractility, muscarinic

    ↓ Automaticity, muscarinic

    ↓ Conduction Velocity, muscarinic
  5. Sympathetic affect on blood vessels of mucosa, skin, and splanchnic beds?
    Constriction, α1, α2
  6. Parasympathetic affect on blood vessels of mucosa, skin, and splanchnic beds?
    Dilation, muscarinic

    (no parasympathetic innervation to most vascular beds, muscarinic receptors are present on endothelial cells. Activation of these receptors results in nitric oxide-mediated vasodilation)
  7. Parasympathetic affect on blood vessels and skeletal muscle?
    Dilation, muscarinic

    (no parasympathetic innervation to most vascular beds, muscarinic receptors are present on endothelial cells. Activation of these receptors results in nitric oxide-mediated vasodilation)
  8. Sympathetic affect on blood vessels and skeletal muscle?
    Constriction, α1

    Dilation, β2
  9. Sympathetic affect on airways?
    Relaxation, β2
  10. Parasympathetic affect on airways?
    Constriction, muscarinic
  11. Sympathetic affect on GI Tract?
    Relaxation, α1, α2, β1, β2

    ↓ Motility
  12. Parasympathetic affect on GI Tract?
    ↑ Motility, muscarinic

    ↑ Spasms, muscarinic
  13. Sympathetic affect on urinary bladder wall, urinary sphincter, and the prostate?
    Relaxation, β2

    Contraction, α1
  14. Parasympathetic affect on urinary bladder wall, urinary sphincter, and the prostate?
    Constriction, muscarinic

    Relaxation, muscarinic
  15. Sympathetic affect on kidney JG cells?
    ↑ Renin Secretion, β1
  16. Sympathetic affect on the uterus?
    Contraction, α1

    Relaxation, β2
  17. Sympathetic affect on the male sex organs?
    Ejaculation, α1
  18. Parasympathetic affect on the male sex organs?
    Erection, muscarinic
  19. Sympathetic affect on the liver and fat cells?
    ↑ glucose output (liver), β2

    ↑ fatty acid output (fat cells), β1 (β3)
  20. Sympathetic affect on pilomotor muscle and sweat glands of the skin?
    contraction (pilomotor muscle), α1

    secretion (sweat glands), muscarinic
