A) During the fight-or-flight response, beta?-adrenergic receptors of the sympathetic nervous system are stimulated, the bronchiolar smooth muscle relaxes, and bronchodilation occurs. Bronchodilators act on the sympathetic nervous system, not the parasympathetic nervous system. Bronchodilators do not decrease the production of mucus or the production of histamine.
B) During the fight-or-flight response, beta?-adrenergic receptors of the sympathetic nervous system are stimulated, the bronchiolar smooth muscle relaxes, and bronchodilation occurs. Bronchodilators act on the sympathetic nervous system, not the parasympathetic nervous system. Bronchodilators do not decrease the production of mucus or the production of histamine.
