Autonomic function

Today, I would like to demonstrate about autonomic function of humans and it's importance. To have the primary idea about about autonomic function is important. There are two systems such sympathetic and parasympathetic. In normal physiological state, sympathetic and parasympathetic should be equal to stabilize the autonomic function. In general term, sympathetic is excitatory and parasympathetic is inhibitory. However, there is some variation between two systems in different conditions. As for exmpale, stress is an impact factor to cause disorganization between two systems. It is thought that stress incresaes the sympathetic activity and relaxation initiates the parasympathetic activity. It is also assumed that meditation for example initiates the parasympathetic activity.
