  1. 3. The sphincters of the urinary system have ______ receptors for SNS stimulation - cause contraction
  2. 4. SNS acts on the ____ receptor on ciliary muscle of iiris to cause relaxation (decreases focus)
  3. 8. ________ reflex - why you may see opposite effect on heart rate than expected when giving a drug
  4. 11. ________ drugs change relaxation of heart
  5. 13. The ______ muscle of the urinary system has beta2 receptors for SNS stimulation - causes relaxation
  6. 14. The autoreceptor for SNS nerves which inhibits NE release uses which receptor type?
  7. 18. Where the sympathetic nervous system directly stimulates via release of ACh to NN receptors (no pre-ganglionic neuron)

  9. 24. M2 receptors are found on the ______ for stimulation via PNS
  10. 25. high level SNS stimulation of b2 receptors on coronary, pulmonary, skeletal, abdominal visceral arteries causes vasodilation because of the release of ______ into blood from adrenal gland
  11. 26. low level SNS stimulation of a1 receptors on coronary, pulmonary, skeletal, abdominal visceral arteries causes ________
  12. 28. ________ drugs change force/contractility of heart
  13. 29. ________ contraction occurs to increase hematocrit in lots of species when a1 is stimulated by SNS
  14. 30. b1 receptors are responsible for activating the _______ system in the kidney when SNS stimualted
  15. 31. type of SNS receptors on heart
