Match the effects with sympathetic or parasympathetic stimulation (or neither) of the heart. (Options may be used more than once or not at all.)
-decreases the contractility of the ventricular muscle
A)effect caused by sympathetic stimulation
B)effect caused by parasympathetic stimulation
C)not brought about by either sympathetic or parasympathetic stimulation

Question

The parasympathetic nervous system primarily affects the heart rate and has little to no effect on ventricular contractility. The sympathetic nervous system increases contractility, so a decrease is not caused by either system.
