The autonomic nervous system is the part of the nervous system of the higher life forms that is not consciously controlled. It is commonly divided into two usually antagonistic subsystems: the sympathetic and parasympathetic nervous system. The autonomic nervous system controls such vital functions as heart rate, dilation of the bronchioles and dilation and constriction of the pupil; the digestive tract is controlled almost completely by autonomic mechanisms.

The cranial sympathetics include sympathetic efferent fibers in the oculomotor, facial, glossopharyngeal and vagus nerves, as well as sympathetic afferent in the last three nerves. The Sympathetic Efferent Fibers of the Oculomotor Nerve probably arise from cells in the anterior part of the oculomotor nucleus which is located in the tegmentum of the mid-brain. These preganglionic fibers run with the third nerve into the orbit and pass to the ciliary ganglion where they terminate by forming synapses with sympathetic motor neurons whose ...

The sympathetic nervous system (SNS) is one half of the autonomic nervous system; the parasympathetic nervous system (PNS) is the other. Sympathetic nervous system - Function. The sympathetic nervous system activates what is often termed the "fight or flight response". This response is also known as sympathico-adrenal response of the body, as the pre-ganglionic sympathetic fibers that end in the adrenal medulla (but also all other sympathetic fibers) secrete acetylcholine, which activates t ...

Art is a great healer. By supplanting apprehension with inspiration and trading stress for relaxation, it tempers human physiology and attitude.

Scientifically speaking, it improvises human brainwave pattern, autonomic nervous system, hormonal balance, brain neurotransmitters, immune system, and blood flow to various organs. Through self-expression, it rejuvenates the creator with an enlightened perception of within and without.

Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), post-viral fatigue syndrome (PVFS) and various other names, is a syndrome of unknown and possibly multiple etiology, affecting the central nervous system (CNS), immune, and many other systems and organs. Most definitions other than the 1991 UK "Oxford", require a number of features, the most common being severe mental and physical depletion, which according to the 1994 Fukuda definition is "unrelieved by rest", and is usually made worse by even trivial exertion (controver ...

The word sympathetic means different things in different contexts. In neurology, the sympathetic nervous system is a part of the autonomic nervous system. In music theory, sympathetic strings are strings on a musical instrument that resonate on their own. In psychology, sympathy is a feeling of compassion or identification with another.

Arousal is a physiological and psychological state involving the activation of the reticular activating system in the brain stem, the autonomic nervous system and the endocrine system, leading to increased heart rate and blood pressure and a condition of alertness and readiness to respond. It is a crucial process in motivating certain behaviours, such as the fight or flight response and sexual activity (see Masters and Johnson's human sexual response cycle, w ...

The nervous system of an animal coordinates the activity of the muscles, monitors the organs, constructs and processes input from the senses, and initiates actions. Prominent participants in a nervous system include neurons and nerves which play roles in such coordination. In animals without brains, the nervous system does not generate or conduct thoughts and emotions. Thus it is the system that animates "animals" (sponges are an exception). Chemicals that target the activity of nerves generally are the most rapidly act ...

Autonomic Computing is an initiative started by IBM in 2001. Its ultimate aim is to create self-managing computer systems to overcome their rapidly growing complexity and to enable their further growth. Autonomic Computing - The problem of growing complexity. A general problem of modern distributed computing systems is that their complexity is increasingly becoming the limiting factor in their further development. Large companies and institutions are employing large-scale computer networks for commun ...

In the anatomy of mammals, the hypothalamus is a region of the brain located below the thalamus, forming the major portion of the ventral region of the diencephalon and functioning to regulate certain metabolic processes and other autonomic activities. The hypothalamus links the nervous system to the endocrine system by synthesizing and secreting neurohormones often called releasing hormones because they function by stimulating the secretion of hormones from the anterior pituitary gland — among them, gonadotropin-releasing ho ...

Autogenic training is a term for a relaxation technique developed by the German psychiatrist Johannes Schultz first published in 1932. It usually involves a series of sessions in which the patients learn to relax their limbs, heart, and breathing. The goal is to induce a pleasant, warm feeling throughout most of the body but induce a feeling of coolness in the forehead. The technique is used against stress-induced psychosomatic disorders. Schultz emphasized parallels to techniques in yoga and meditation. However, autogenic training is devoid of any mysticism; rather, it is ...

The appetite is the desire to eat food, felt as hunger. Appetite exists in all higher lifeforms, and serves to regulate adequate energy intake to maintain metabolic needs. It is regulated by a close interplay between the digestive tract, adipose tissue and the brain. Decreased desire to eat is termed anorexia, while polyphagia (or "hyperphagia") is increased eating. Dysregulation of appetite contributes to anorexia nervosa and cachexia on one side, and obesity on the other side of the spectrum. Appetite - Regulation. ...

The central nervous system (CNS) represents the largest part of the nervous system. Together with the peripheral nervous system, it has a fundamental role in the control of behavior. Since the strong theoretical influence of cybernetics in the fifties, the CNS is conceived as a system devoted to information processing, where an appropriate motor output is computed as a response to a sensory input. Yet, many threads of research suggest that motor activity exists well before the maturation of the sensory systems and then, that the senses only influence behaviour without dictating it. This h ...

Acute stress reaction is a psychological condition arising in response to a terrifying event. "Acute Stress Response", was first described by Walter Cannon in the 1920s as a theory that animals react to threats with a general discharge of the sympathetic nervous system. The response was later recognized as the first stage of a general adaptation syndrome that regulates stress responses among vertebrates and other organisms. The onset of a stress response is associated with specific physiological actions in the sympatheti ...

The solar plexus, also known as the celiac plexus, plexus cœliacus or plexus solaris, is an autonomous cluster of nerve cells (see Plexus) in the human body behind the stomach and below the diaphragm near the celiac artery in the abdominal cavity.

The sympathetic nervous system activates what is often termed the "fight or flight response". This response is also known as sympathico-adrenal response of the body, as the pre-ganglionic sympathetic fibers that end in the adrenal medulla (but also all other sympathetic fibers) secrete acetylcholine, which activates the secretion of epinephrine and to a lesser extent norepinephrine from it. Therefore this response that acts primarily on the cardiovascular system is mediated directly via impulses transmitted through the sympathetic nervous system and indirectl ...
