There are two divisions of the autonomic nervous system. The sympathetic system responds to stress, when it speeds the heart rate, increases blood pressure, and generally prepares the body for action. The parasympathetic system is more important when the body is at rest, since it slows the heart rate, decreases blood pressure, and stimulates the digestive system.

International Association for the Study of Pain Technical Corner from IASP Newsletter November/December 1998 This section, edited by Charles B. Berde, MD, PhD, and Michael C. Rowbotham, MD, presents timely topics in pain research and treatment. Testing the Autonomic Nervous System Paola Sandroni, MD, PhD Department of Neurology, Mayo Clinic, Rochester, Minnesota, USA The autonomic nervous system (ANS) is an extensive neural network whose main role is to regulate the milieu intérieur by controlling homeostasis and visceral functions. Although most functions regulated by the ANS are out of conscious control, emotions and somatosensory inputs profoundly influence the ANS. Observing the marked vasomotor and sudomotor changes after traumatic nerve injury, it became apparent long ago that the ANS plays an important role in pain modulation and perception. Despite the debate on whether the role of the sympathetic nervous system in generating and sustaining certain pain syndromes is significant, specialists in pain management have sought tools for investigating the ANS. Anatomy The ANS has components at every level of the nervous system. The central component, also known as the central autonomic network (CAN), includes the insula, medial prefrontal cortex, hypothalamus, amygdala, ventrolateral medulla, nucleus of the tractus solitarius (NTS), nucleus parabrachialis, periaqueductal gray, and the circumventricular organs.

45. Autonomic Nervous System Autonomic axons leaving the central nervous system are preganglionic (= presynaptic). Generally, the pre- to post-synaptic neuron ratio is very high, http://sky.bsd.uchicago.edu/lcy_ref/synap/autonomic.html

A UTONOMIC processing and innervation directs many of the homeostatic functions necessary for basic life processes. All autonomic nerves are motor. I repeat: ALL autonomic nerves are motor. Targets include the pacemaker of the heart, and the smooth muscle and glands of viscera. There are three major subdivisions of the ANS. The sympathetic division acts occasionally in response to emergencies. The parasympathetic division is composed of many independent subsets of nerves that individually activate portions of parasympathetic innervation. Finally, the enteric nervous system is a large but diffuse number of neurons dispersed throughout the muscular walls of hollow viscera. Enteric neurons receive input from the parasympathetic and sympathetic, but largely this network is independent of the CNS. The Autonomic Nervous System by David L. Atkins, Prof. of Biology Washington, DC A LTHOUGH the sympathetic and parasympathetic systems are largely antagonistic in their action, they share anatomical generalities. Autonomic axons leaving the central nervous system are preganglionic (= pre-synaptic). Generally, the pre- to post-synaptic neuron ratio is very high, so that one preganglionic fiber will excite (or inhibit) very many postganglionic neurons...sometimes as many as 8000. In this way a simple instruction can be spread economically to a large number of effectors. These are the only ganglionic synapses in the nervous system. The two systems function below conscious levels, although their action may be quite obvious to that person. NowClick below to explore these two subsystems in detail.

The autonomic nervous system controls automatic activities which are free of will ( involuntary such as heart beat, breathing, peristalsis etc.) Thus, this system deals with the internal environment of the body (homeostasis). The autonomic nervous system is connected with the central nervous system and is divided into two parts. (1) Sympathetic nervous system and (2) Parasympathetic nervous system. The main structural and functional similarities and differences are given in the following table. Sympathetic Nervous System Parasympathetic Nervous System Contains nerve fibers on which there is no voluntary control. (Involuntary nerve fibers.)

The autonomic nervous system reacts when a person is facing a dangerous or frightening situation and will automatically increase the heart rate and breathing and move blood to the muscles. The autonomic nervous system differs from the voluntary nervous system, which allows a person to control the muscles and body movements.

Gene Therapy Autonomic Nervous System: The autonomic nervous system serves as a relay station to the visceral organs of the body. It is an efferent system, meaning it sends out motor impulses to the organs. It regulates many body functions to maintain homeostasis. Most motor pathways usually have one motor neuron from the brain or spinal cord. In the autonomic nervous system, the message is transferred at the synapse from one neuron to a second one that carries it to the muscle or gland cell. The autonomic nervous system is actually part of the peripheral nervous system in that it consists of motor portions of some cranial and spinal nerves. Because it's functioning is so specialized, however, the ANS is usually discussed as a separate entity. The autonomic nervous system consists of certain motor neurons that conduct impulses from the spinal cord or brain stem to cardiac muscle tissue, smooth muscle tissue, and glandular tissue.

In contrast to the voluntary nervous system , the "involuntary" or autonomic nervous system is responsible for homeostasis , maintaining a relatively constant internal environment by controlling such involuntary functions as digestion respiration perspiration , and metabolism , and by modulating blood pressure . Although these functions are generally outside of voluntary control, they are not outside our awareness, and they may be influenced by one's state of mind. The autonomic nervous system is divided into two subsystems, the sympathetic and the parasympathetic , which work in tandem, either in a synergistic or an antagonistic way. The sympathetic system is responsible for providing responses and energy needed to cope with stressful situations such as fear or extremes of physical activity. In response to such stress, the sympathetic system: raises blood pressure, heart rate , and the blood supply to the skeletal muscles at the expense of the gastrointestinal tract kidneys , and skin ; dilates both the pupils and the bronchioles , providing improved vision and oxygenation ; and generates needed energy by stimulating glycogenolysis in the liver and lipolysis in adipose tissue . In general, it serves to stimulate organs and to mobilize energy.

Unit 4. Neurons, Hormones, and the Brain (cont'd) The Autonomic Nervous System: The brain functions we have discussed so far are primarily voluntary functions that enable us to think and to function in relation to the world outside of our bodies. There is, however, a part of the nervous system that is concered with regulating internal bodily functions that are generally considered to be involuntary or automatic, such as digestion, heart rate, blood pressure, glandular secretions, and tear production. This part of the nervous system is called the autonomic nervous system . The autonomic nervous system is made up of two parts with opposite functions: the sympathetic nervous system and the parasympathetic nervous system autonomic nervous system = sympathetic nervous system + parasympathetic nervous system The sympathetic nervous system is often referred to as the " fight or flight " system. It prepares the body for action. It is active when we are anxious or otherwise emotionally aroused. Activity in the sympathetic nervous system increases heart rate and blood pressure. The parasympathetic nervous system is sometimes referred to as the "vegetative" system. It nurtures and rebuilds the body. The parasympathetic nervous system is active during relaxation and rest. Activity in the parasympathetic nervous system decreases heart rate and blood pressure and promotes digestion.
