Saved Help nich of the following statements is true about the regulation of the heart by the autonomic nervous system? Multiple Choice The autonomic nervous system initiates the heart's contractions. Sympathetic nerves release.norepinephrine at adrenergic nerve endings that decreases the activities of the sinoatrial and atrioventricular nodes. Parasympathetic nerves release acecholine at cholinergic nerve endings that decreases the activities of the sinoatrial and atrioventricular nodes. The heart is only regulated by the sympathetic nerves, not the parasympathetic nerves.
Baroreceptor reflex-mediated increases in sympathetic activity causes vasodilation, bringing elevated blood pressure back to normal. True or False True False
Which of the following is associated with elevated parasympathetic activity? shifting blood flow away from gastrointestinal tract enhanced absorption of nutrients increased heart rate increased contractile force of the heart both Cand D
The next patient seen by the same doctor was suffering from hyperkalemia and was experiencing cardiac arrhythmias. Which of the following reason/s explain/s why this patient was experiencing cardiac arrhythmias? O hyperkalemia leads to an increase in action potential generation because potassium ions in the ECF makes the resting membrane potential more negative O hyperkalemia leads to a decrease in action potential generation because the potassium ion level in the ICF will cause hyperpolarization O hyperkalemia leads to an increase in action potential generation because the high level of potassium ions in the ICF will make achieving threshold easier O a and b
