Bronchial smooth muscle contains both sympathetic and parasympathetic innervation.
False
note: bronchial smooth muscle do not contain sympathetic neuron innervation
Discuss the 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)
- What stimulates the 2 receptors above?
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)
(T/F)
To get bronchodilation you can either use a sympathetic antagonist or parasympathetic agonist
False
Correct statement: To get bronchodilation you can either use a sympathetic agonist or parasympathetic antagonist
Sympathetic = bronchodilation
Parasympathetic = bronchoconstriction
All of the following are true regarding asthma EXCEPT:
A. Intermittent attacks of shortness of breath
B. Inflammation of the airways
C. Bronchial hyper-reactivity
D. Leads to irreversible airway obstruction
E. All of the above are true
D. Leads to irreversible airway obstruction
note: asthma can be caused by cold air, allergens and some drugs
_________ is acute severe asthma that usually requires hospitalization.
Status asthmaticus
Discuss Immediate vs Late phases of asthma:
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
All of the following are true regarding the Immediate phase of asthma EXCEPT:
A. activation of cysLTs causes bronchospasms
B. reversed by beta2 agonist
C. reversed by cysLT-receptor antagonist
D. reversed by glucocorticoids
E. reversed by theophylline
D. reversed by glucocorticoids
Late phase asthma = inhibited by glucocorticoids
Early phase asthma is reversed by:
- Beta2-agonist
- cysLTs-receptor antagonist
- theophylline
All of the following are true regarding the Late phase of asthma EXCEPT:
A. associated with Th2 response
B. associated with EMBP and ECP
C. leads to bronchospasms, wheezing and coughing
D. inhibited by glucocorticoids
E. all of the above are true regarding the late phase of asthma
E. all of the above are true regarding the late phase of asthma
What are the two main drug classes used to tx asthma?
- Which of the two classes of drugs used to tx asthma mainly targets the immediate phase?
Bronchodilators = Immediate phase
Anti-inflammatory agents = Immediate and Late phase
All of the following are examples of Bronchodilators EXCEPT:
A. Fluticasone
B. Montelukast
C. Ipratropium
D. Albuterol
E. Salmeterol
A. Fluticasone
Bronchodilators:
- Albuterol
- Ipratropium
- Montelukast
- Salmeterol
Anti-inflammatory agents:
- Fluticasone
- Budesonide
- Prednisolone
- Salbutamol
- Hydrocortisone
Bronchodilators are:
A. Beta1 agonist
B. Beta2 agonist
C. Beta1 antagonist
D. Beta2 antagonist
B. Beta2 agonist
Which of the following is a Beta2 agonist that may be supplied as an inhalent, tablet, or syrup and is shorter acting?
A. Albuterol
B. Salmeterol
C. Ipratropium
D. Montelukast
A. Albuterol
Which of the following is a short acting Beta2 agonist?
A. Albuterol
B. Salmeterol
C. Ipratropium
D. Montelukast
A. Albuterol
Which of the following is a short acting Muscarinic ACh antagonist?
A. Albuterol
B. Salmeterol
C. Ipratropium
D. Montelukast
C. Ipratropium
Short acting bronchodilators:
- Albuterol = beta2 agonist
- Ipratropium = Muscarinic ACh antagonist
Which of the following is a longer acting Beta2 agonist that is supplied as a dry-powder?
A. Albuterol
B. Salmeterol
C. Ipratropium
D. Montelukast
B. Salmeterol
Albuterol = short acting beta2 agonist
Salmeterol = long acting beta2 agonist (dry-powder)
Ipratropium = short acting muscarinic ACh antagonist
Montelukast = leukotriene receptor antagonist
