Beta blockers (beta-adrenergic antagonists) are drugs used to treat a variety of medical conditions (e.g., glaucoma, heart problems, anxiety disorders). These drugs have what effect on the actions of neurons on their effectors, and in which autonomic motor pathway (parasympathetic, sympathetic)?

Question

Quizplus · Accepted Answer

Beta blockers decrease the actions of neurons on their effectors in the sympathetic nervous system. They block the effects of epinephrine and norepinephrine, which are neurotransmitters released by sympathetic neurons. This leads to a decrease in heart rate, blood pressure, and other sympathetic responses. Beta blockers do not have a significant effect on the parasympathetic nervous system.
