Autonomic Control of Bronchial Smooth Muscle

  • Which of the following innervates bronchial smooth muscle?
    • A. Sympathetic system
    • B. Parasympathetic system
  • Which of the following causes bronchoconstriction?
    • A. Sympathetic system
    • B. Parasympathetic system
  • What type of receptors are found on bronchial smooth muscle? (2)
    • Muscarinic and Beta2 adrenergic receptors
  • What stimulates the 2 receptors above?
    • Ach = muscarinic receptors
    • Epi = Beta2 receptors

Sympathetic = bronchodilation

Parasympathetic = bronchoconstriction

note: Bronchial smooth muscle DONT have sympathetic neuron innervation
note: Beta2 adrenergic receptors are NOT stimulated by Norepinephrine (only Epi)

Q

Discuss Immediate vs Late phases of asthma:

A

Immediate phase:

  • Allergen activates mast cells
  • cysLTs and chemotaxins are released
  • cysLTs causes bronchospasms
  • Reversed by:
    • Beta2 adrenoceptor agonist
    • CysLT-receptor antagonist
    • Theophylline

Late phase:

  • Chemotaxins that were activated by mast cells activates the Th2 response and eosinophils
  • cysLTs lead to airways inflammation and airway hyper-reactivity
  • EMBP and ECP leads to epithelial damage which also contributes to airway hyper-reactivity
  • The result of the 2 bullets above is bronchospasms, wheezing and coughing
  • Inhibited by glucocorticoids
