  • Sympathetic: Norepinephrine is released at the postganglionic nerve endings. Epinephrine is released from the adrenal medulla

    • Parasympathetic: Acetylcholine is released at the ganglia and postganglionic nerve endings (applies to both systems)

  • alpha 1- found on glands, smooth muscles membranes of arteries, veins, and eyes
  • alpha 2- located on adrenergic nerve endings
  • beta 1- located in the heart
  • beta 2- located on smooth muscle, lungs, skeletal muscle & coronary arteries

    • Arteries & veins- Vasoconstriction (same effect with EPI)
    • Eye- Dilation (same effect with EPI)
    • Heart- Moderate increase in heart rate and contraction
    • Adrenergic nerve ending- a decreased release of norepinephrine

  • muscarinic- located on glands, cardiac and smooth muscle; also at postganglionic nerve endings 
  • nicotinic 1 (Nn)- located at ganglia of sympathetic and parasympathetic nerve endings 
  • nicotinic 2 (Nm)- located on neuromuscular junction of skeletal muscle, somatic neurons

    • Heart- decreases heart rate
    • Lungs- decreases respiration (bronchoconstriction)
    • Eyes- pupillary constriction
    • Gastrointestinal system- increases digestion 
    • Relaxes muscles

    • alpha 1- vasoconstriction, increased blood pressure
    • alpha 2- decreases release of norepinephrine
    • beta 1- increased heart rate and contraction
    • beta 2- bronchodilation, increased blood flow to heart and skeletal muscle

    Sympatholytics: adrenergic blockers, antagonists

    • Direct- mimics acetylcholine and bind to musarinic receptors; increase GI actions and urinary function, causes pupillary constrction
    • Indirect- inhibit acetylcholine and causes accumulation; increases strength of muscular contractions

    Parasympatholytics: antagonists, anticholingerics
    • Acts as a blocking drug by competitive antagonism of acetylcholine
    • decrease vagus nerve activity in heart; increases heart rate
    • reduces GI secretions
    • produce depressant effect
