Questions And Correct Answers
What are receptor sites? - answer✔✔they are found on airway smooth muscle, bronchial
epithelium and pulmonary, & bronchial blood vessels
Anticholinergic - answer✔✔a drug BLOCKING a receptor
Adrenergic - answer✔✔a drug STIMULATING a receptor
Sympatholytic - answer✔✔a drug blocking or inhibiting the effects of the sympatric nervous
system
Parasympatholytic - answer✔✔a drug blocking or inhibiting the parasympatholytic nervous
system (blocking acetylcholine)
Sympathomimetic - answer✔✔a drug causing stimulation of the sympatric nervous system
(produces adrenergic effect)
Cholinergic - answer✔✔cells that respond when stimulated by the neurotransmitter
(acetylcholine)
what is the response if the adrenergic receptor site is stimulated? - answer✔✔broncho dilation
What is the neurotransmitter that acts on the parasympathic receptor? response? end results? -
answer✔✔releases a parasympathic axon is acetylcholine and it causes cholinergic response
broncho constriction
what is the neurotransmitter that acts on the sympatric receptor? response? end results? -
answer✔✔released a sympatric axion is epinephrine (adrenalin) and it causes an adrenergic
response
broncho dilation
what causes degranulation of mast cells? - answer✔✔repeated exposure to the antigen
what are the chemical mediators that are released when mast cells degranulation? -
answer✔✔histamine, heparin, and SRS-A
Histamine - answer✔✔increased bronchial gland secretion causing increased amount of mucous
in the airways
SRS-A - answer✔✔direct strong bronchoconstriction and increased permeability causing edema
what is a muscannic effect? - answer✔✔vagal stimulation causes the release of acetylcholine-
cholinergic effect
muscannic system- primarily responsible for bronchospasms in lung
what types of receptors are found in the lungs? - answer✔✔sympatric (adrenergic) &
parasympathetic (cholinergic)
Hypersensitivity - answer✔✔an allergic or immune medicated reaction to a lung
Tolerance - answer✔✔a decreasing intensity of response seen over time
Tachyphylaxis - answer✔✔a rapid decrease in responsiveness to a drug
ALPHA - what is the response if the following adrenergic receptors sites are stimulated by a
drug? - answer✔✔peripheral vasoconstriction (vasonconstricts vessels in the upper airway to
treat stridor)
mild bronchoconstriction
Agonist - answer✔✔drug that stimulates a receptor
Antagonist - answer✔✔drugs that block or inhibit a receptor
Pharmacy - answer✔✔the preparation and dispensing of drugs
Drug - answer✔✔any chemicals that alters the organism functions or processes
Toxicology - answer✔✔the study of toxic substances and their pharmacological actions
including antidotes and poison control
chemical name - answer✔✔name indicating the drugs chemical structures
generic name - answer✔✔name assigned to a chemical by the (USAN) counsil when the
chemical appears to have therapeutic use and manufacturer wants to market the drug
