  1. The functions for the ANS system is regulating:
    • Blood Pressure
    • Heart Rate
    • GI Tract
    • Salivary Gland Secretions
    • Bronchial Smooth Muscle
  2. The ANS relies on specific neutot and a variety of rceptor to initiate functional responses in target tissues
    • Neurotransmitters
    • Receptors
  3. ANS drugs are used in Dentistry as:
    • Vasoconstrictors
    • Used to increase/decrease saliva flow
  4. PANS
    Parasympathetic
  5. SANS
    Sympathetic
  6. Each division of the ANS has:
    • 1.Afferent (sensory) fibers
    • 2. Efferent (motor) fibers
    • 3. Central Intergrating Areas
  7. PANS is concerned with?
    • Conservation of body process
    • ex: digestion & intestinal tract
    • Constricted pupils
  8. SANS is designed for?
    • Emergencies
    • [fight-or-flight]
    • ex: dilated pupils
  9. Neurotransmitters
    • Are released because of nerve action potential or pharmacologic agents
    • Interact with receptors and produce an effect
  10. Drugs can modify the ANS by altering blank of neurotransmitters
    • Synthesis
    • Storage
    • Release
    • Receptor
    • Disposition
  11. A drug that stimulates the PANS is called:
    • P+
    • Cholinergic
    • Parasympathomimetic
  12. A drug that blocks the PANS is called:
    • P-
    • Anticholinergic
    • Parasympatholytic
    • Cholinergic blockers
  13. A drug that stimulates the SANS is called:
    • S+
    • Sympathomimetic
    • Adrenergic
  14. A drug that blocks the SANS is called:
    • S-
    • Adrenergic Blockers
    • Sympathetic Blockers
    • Sympatholytic
  15. Cholinergic Agents
    • Parasympathomimetic
    • Direct: acts on receptor
    • Indirect: causes release of neurotransmitter
  16. Adverse Effects of Cholinergic Agents:
    • Salivation
    • Lacrimation
    • Urination
    • Defecation
  17. Mixing more than one group possessing anticholinergic effects can lead to toxicu
    Toxicity
  18. Beta 1
    Stimulation will increase heart rate and force of contraction
  19. Beta 2
    • Stimulation will relax smooth muscle in airways
    • [treats bronchodilation]
  20. Beta Blockers
    Block the Beta 1 receptor to reduce heart rate and BP
  21. Beta 2 Agonists
    Stimulates Beta 2 to cause bronchodilation
