Explanation / Answer

Action potentials arriving at the sinoatrial and atrioventricular nodes of the heart cause Acetyl choline to be released Action potentials travel down the preganglionic nerve fibers of the vagus nerve, towards the effector organs. These impulses arrive at the cardiac plexus where secretion of acetylcholine creates an action potential in the preganglionic fiber Also known as the craniosacral division, the parasympathetic nervous system has fibers exiting the CNS at the medulla oblongata This parasympathetic neurotransmitter causes the heart rate and contractility to decrease The impulse arrives relatively quickly to the heart as the remaining distance is comparatively short to the postganglionic fibers of the sympathetic nervous system
