What is the role of the autonomic nervous system?
The primary role of the autonomic nervous system is to regulate basic body functions such as heart rate and breathing. These functions are sufficiently important that voluntary control is minimal. The individual can control his degree of breathing, but cannot stop it completely because breathing will continue as soon as the consciousness is lost. Other functions such as heart rate, digestion and body temperature are even less voluntary controls.
The human nervous system is divided into two subsystems: a central nervous system that consists of a spinal cord and brain, and a peripheral nervous system that includes all other nerves. Subsequent division of the peripheral nervous system into autonomous and sensory somatic systems can be partially differentiated by the degree of conscious control that is necessary for functioning. The sensory somatic functions such as muscle activity and the processing of sensory information are below a large amount of voluconine. Autonomic functions such as breathing and circulation can be awareEdit, but generally are more reflexive and automatic than somatic.
nerves that control the organs of smooth muscle, such as intestines, heart muscles, breathing and glands of the body, form an autonomous nervous system. It is divided into three main components: a sympathetic nervous system that activates these systems as needed; a parasympathetic system that releases it; and enteral system that regulates the digestive system. The autonomic system is also responsible for monitoring internal conditions and directing resources to or from specific organs as needed to keep the body optimally.
reaction to danger is the secondary role of the autonomic nervous system. The sympathetic branch controls the reaction of a fight or flight that allows whole Žers, including humans to respond to threats. When the danger is perceived, the sympathetic nervous system affects and refers to blood from the periphery of the body and towards the heart, lungs and brain. RaisedThe heart rate and breathing disrupt the person and prepare him either to fight or to escape the situation.
after the end of the danger is the domain of the parasympathetic branch of the autonomous nervous system. Although the autonomous nervous system is primarily reflective, some qualified experts are able to hire it to increase relaxation and concentration. Breathing is the fastest controlable autonomous function and many people are able to use breath control to relax, reduce stress and minimize pain. Others use yoga and meditation exercises to increase concentration and evoke a sense of calm by running the parasympathetic system to slow down the heart rate and increase their circulation.
