Parasympathetic nervous system is part of the nervous system which serves the purpose to slow down the heart rate, increase the activity of the intestine and gland, and to relax down the sphincter muscles. The autonomic nervous system comprises of two different systems out of which one is the parasympathetic nervous system while the other is the sympathetic nervous system. The purpose of the sympathetic nervous system in contrast to the parasympathetic nervous system is to raise the blood pressure, constrict the blood vessels while also accelerating the heart rate. The parasympathetic nervous system is present in the brain stem near to the lower section of the spinal cord. The purpose of the parasympathetic nervous system is to oppose all that the sympathetic nervous system is doing. This means that the parasympathetic nervous system works to slow down the heart rate, lower the blood pressure, dilate the blood vessels, constrict the pupils and stimulate digestive secretions.
Basically the parasympathetic nervous system is there to counteract all that is being done by the opposing sympathetic nervous system. This helps create a healthy balance for the body. While the sympathetic nervous system acts as the accelerator the parasympathetic nervous system is present to act as the brake. Often an acronym is used to describe the functions being performed by the parasympathetic nervous system called SLUDD. This acronym for the parasympathetic nervous system stands for salivation, lacrimation, urination, digestion and defecation. These tow nervous systems together forming the autonomic nervous system is very important for the well being of any human being.
Any problems occurring in the parasympathetic nervous system are termed as parasympathetic nervous system disorders. There are certain symptoms that you should look out for to ensure that your parasympathetic nervous system and sympathetic nervous system, both are working fine.
