just final answer. true or false.  Training will decrease heart rate through decreasing firing rate of the SA node.

A EEF EE D.A. V Membrane Potential (mv) +20 -20 14. Define the term pacemaker potential (=drifting potential) and be able to identify it when given a graph of an action potential in an autorhythmic cell such as the one below. -40 EL T -60 0 sec - ^^ 0.8 sec = 800 msec Time daRbCoDdEe AaBbCcD ABNC ADVE Emphasis Heading 1 I Normal 1.6 sec -1600 msec

True or false?

Can you please answer this question and say the correct letter

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.
