Beta and Alpha Adrenergic Receptors

  1. this receptor acts in smooth muscle glands and has greater sensitivity to NE than EPI
    alpha 1
  2. activates phospholipase C which increases Ca2+

    excitatory
    alpha 1
  3. this receptor is presynaptic and has a greater sensitivity to NE than EPI
    alpha 2
  4. decreases adenylate cyclase activity which decreases cAMP

    excitatory and inhibitory
    alpha 2
  5. this receptors acts in hear muscle and kidney, the sensitivity for NE and EPI is equal
    beta 1
  6. increases adenylate cyclase activity which increases cAMP

    excitatory
    beta 1
  7. this receptor acts in blood vessels and smooth muscles, the sensitivity to EPI is greater than NE
    beta 2
  8. increased adenylate cyclase activity which increases cAMP

    inhibitory
    beta 2
  9. This receptor when stimulated will cause

    contraction (vasoconstrict) ateriole smooth muscles 
    contraction (vasoconstrict) veins (smooth muscle)
    secretion from salivary glands 
    contraction of pilomotor muscles
    alpha 1
  10. This receptor when stimulated will cause:

    excitatory response in heart cells
    renin secretion in kidney
    beta 1
  11. This receptor when stimulated will cause:

    relaxation (vasodilation) vessels of skeletal muscles
    relaxation (dilation) of bronchiole smooth muscle 
    relaxation of the uterus
    relaxation of bladder smooth muscle
    beta 2
  12. Drug for non-obstructuve urinary retention
    muscarinic agonist (simulates receptors)

    example: bethanechol
  13. Drug for vagal-induced fainting and dry secretions
    muscarinic receptor antagonist (blocks receptor)

    example: atropine
  14. Drug for myasthenia gravis
    Acetylcholinesterase inhibitors 


    example: neostigmine
  15. Drug for nasal decongestion
    alpha 1 agonists

    example: phenylephrine
  16. Drug for hypertension (2)
    alpha 1 antagonist

    example: prazocin

    beta 1 antagonist

    example:atenolol
  17. Drug for relieving asthma attack (relaxes bronchiole SM)
    beta 2 agonist

    example: albuterol
