Set up your SpikeRecorder software to begin recording heart rate. The word "autonomic," meaning involuntary, is related to the word "autonomous," meaning independent. In this example, there is widespread vasodilation (due to inflammation), increased permeability of capillaries and venules (a large amount of blood fluid leaves the vessel and enters the tissues), hypoperfusion (not enough blood is being passed through) of major organs and this results in multi-system organ failure due to not enough oxygen, not . If there isn't a real threat, and we do not need the mobilization of our protective mechanisms, then we need to recruit our parasympathetic . Ganglionic receptors: These are the nicotinic receptors present on the neuronal cell bodies in the ganglia of the parasympathetic system. Scott Dutfield The sympathetic nervous system is an energy-expending system that has an ergotrophic function. Under stressful circumstances, the entire sympathetic nervous system can be activated, resulting in an immediate widespread reaction, which is called the fight-or-flight . Research suggests that distinct types of nerve cells, called neurons, control these different physical reactions by directing the action of skeletal muscle, cardiac muscle and gland secretion.
