	Sympathetic nervous system - Wikipedia, the free encyclopedia
		This response is also known as sympatho-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 adrenaline (epinephrine) and to a lesser extent noradrenaline (norepinephrine) from it.
		Sympathetic nerves originate inside the vertebral column, toward the middle of the spinal cord in the intermediolateral cell column (or lateral horn), beginning at the first thoracic segment of the spinal cord and are thought to extend to the second or third lumbar segments.
		The first synapse (in the sympathetic chain) is mediated by nicotinic receptors physiologically activated by acetylcholine, and the target synapse is mediated by adrenergic receptors physiologically activated by either noradrenaline or adrenaline.

	sympathetic magic
		Sympathetic magic is the basis for most forms of divination.
		Sympathetic magic is the basis for psychometry, the claim of psychic detectives that touching an item belonging to a victim gives magical contact with the victim.
		Beyerstein also explains many notions of graphologists as little more than sympathetic magic, e.g., the notion that leaving wide spaces between letters indicates a proneness to isolation and loneliness because the wide spaces indicate someone who does not mix easily and is uncomfortable with closeness.

	The Sympathetic Nervous System
		Excitement (an internal stimulus) or a long jog (an external stimulus) may stimulate the same level of sympathetic arousal that is mediated in the face of threat (Braunwald et al., 2001).
		The context in which threat occurs, the perception of the degree of danger, and the ability to successfully escape from a situation all affect the degree of SNS response.
		Activation of the global response and cortisol secretion are costly, both on an energetic level due to the degree to which glucose and metabolites must be mobilized, and on a behavioral level due to the effects of epinephrine and norepinephrine, which increase irritability and emotional reactivity, and require time reabsorption (Ganong, 2001).

	Autonomic nervous system - Wikipedia, the free encyclopedia
		Sympathetic ganglia are located in two sympathetic chains close to the spinal chord: the prevertebral and pre-aortic chains.
		The sympathetic nervous system is frequently referred to as the "fight or flight" system, as it has a stimulatory effect on organs and physiological systems.
		At the effector organs, sympathetic ganglionic neurons release noradrenaline (norepinephrine) to act on adrenergic receptors, with the exception of the sweat glands and the adrenal medulla:

	SYMPATHETIC NERVOUS SYSTEM AND PAIN: A CLINICAL REAPPRAISAL
		At the same time, this sympathetic- sensory coupling was believed to be part of a vicious circle, where the abnormal afferent activity - via sensitized central nervous (spinal cord) structures - could maintain sympathetic hyperactivity and consequently pain (Livingston 1976).
		The patients of the first group are characterized by the occurrence of a rather complex clinical symptomatology, in whom predominantly the distal part of the extremity is affected, where the symptoms - independently of the kind and location of a preceding lesion - appear in a glove- or sock-like distribution manner.
		Consistent signs of sympathetic hyperactivity are not found in SMP and autonomic changes, which may be present inside the lesioned area (Frost et al 1988), can be related to denervation and reinnervation of sympathetic effector organs.

	sympathetic nervous system studied at interprofessional...
		The profound effects of sympathetic nervous system function on human physiology were emphasized at the most recent interprofessional symposium of the American Chiropractic College of Thermology (ACCT).
		The sympathetic nervous system, controlling vascular tonus, skin temperature, sweating and piloerection, has lent itself only to more obscure laboratory testing procedures such as electrical skin resistance and time-intensive thermometric testing of multiple discrete regions of skin temperature.
		The relevant regions showing sympathetic nervous dysfunction (displayed by surface temperature abnormalities) were treated with photonic stimulation, which produced immediate physiologic changes in sympathetic function.

	The ANS
		The sympathetic nerves reach their end-organs through more devious pathways down the spinal cord to clusters of sympathetic nerve bodies (ganglia) alongside the spine where the messages are relayed to other nerve bodies (or neurons) that travel to a large extent with the blood vessels to all parts of the body.
		However, the final transmission of messages from the sympathetic nerves to the end-organs or cells that they innervate is conveyed by the release of norepinephrine (noradrenaline) with at least one important exception, namely the sympathetically conveyed stimulus to the sweat glands which is transmitted by acetylcholine.
		From these nuclei sympathetic stimuli conveyed by the cardiac nerves cause acceleration of the heart rate, probably complemented by simultaneous reduction in the parasympathetic stimuli via the vagus nerves which slow the heart rate.

	Sympathetic ophthalmia definition - Medical Dictionary definitions of popular medical terms
		Sympathetic ophthalmia: An autoimmune eye disease in which a penetrating injury to one eye produces inflammation in the uninjured eye.
		(The injured eye is termed the "exciting" eye while the uninjured one is the "sympathetic" eye.) The original eye injury always involves the uvea, specifically the ciliary body, releasing uveal pigment into the bloodstream.
		The time between the injury in the exciting eye and the onset of disease in the sympathetic eye is generally 2 weeks to 2 months.

	Reflex Sympathetic Dystrophy
		With reflex sympathetic dystrophy, swelling and sweating, changes in blood flow in a localized area, or tissue changes occur along with the pain.
		Reflex sympathetic dystrophy can occur after any trauma to the arms or legs, including sprains or fractures; after surgery; after any injury that damages blood vessels or nerves; or after brain injury.
		Reflex sympathetic dystrophy is diagnosed through a combination of medical history and physical examination.

	Cervical and Lumbar Sympathetic Nerve Block
		The sympathetic nerves run on the front surface of the spinal column (not in the spinal canal with the nerves from the central nervous system).
		The sympathetic nerves are part of the autonomic nervous system which basically controls functions.
		A sympathetic nerve block involves injecting medicine around the sympathetic nerves in a lumbar or cervical area.

		Reflex Sympathetic Dystrophy (RSD) is a somewhat rare, complicated and devastating disease.
		This system has two subdivisions: the sympathetic and the parasympathetic nervous systems and each oppose the other thus; the sympathetic system is the “fight” component of the well-known "fight or flight" response.
		Reflex Sympathetic Dystrophy is one form of disturbance of the function of the autonomic nervous system as outlined above.

	eMedicine - Reflex Sympathetic Dystrophy : Article Excerpt by: Don R Revis, Jr, MD
		Background: Reflex sympathetic dystrophy (RSD) is a clinical syndrome of variable course and unknown cause characterized by pain, swelling, and vasomotor dysfunction of an extremity.
		In patients with either of these conditions, evidence of sympathetic mediation of the pain (ie, improvement with sympathetic blockade) may or may not be present.
		At least partial sympathetic mediation of this phenomenon is likely because of the ability of sympathetic nerve blockade to relieve pain and other features of RSD in some patients.

	Reflex Sympathetic Dystrophy Prolotherapy
		It is a pain syndrome that occurs due to an increase in the activity of the sympathetic nervous system.
		The result of sympathetic stimulation on the blood vessels causes them to constrict, therefore, decreasing the blood supply to the tendons, ligaments, bones, and skin of the limb.
		RSD patients may receive multiple sympathetic blocks, to the point of having anesthetic pumps placed in their backs, or even have the sympathetic nerves severed in an attempt to find relief from their pain.

	p990624a - Reflex Sympathetic Dystrophy
		Abstract: BACKGROUND: Reflex sympathetic dystrophy/complex regional pain syndrome type I (RSD/CRPS I) is a painful neuropathic disorder that may develop as a disproportionate consequence of a trauma affecting the limbs without overt nerve injury.
		To quantify sympathetic vasoconstrictor function, phasic (induced by deep inspiration) and tonic (induced by controlled thermoregulation) sympathetic reflexes were analyzed.
		The term sympathetically maintained pain (SMP) was also evaluated and considered to be a variable phenomenon associated with a variety of disorders, including CRPS types I and II.

	Reflex sympathetic dystrophy
		Reflex sympathetic dystrophy is the feeling of pain associated with evidence of minor nerve injury.
		There are several theories such as sympathetic overflow (over activity), abnormal circuitry in nerve impulses through the sympathetic system, and as a post-operative complication for both elective and traumatic surgical procedures.
		The diagnosis is simple and confirmed by a local anesthetic block along sympathetic nerve paths in the hand or foot, depending on whether an arm or leg is affected.

	Reflex Sympathetic Dystrophy
		Reflex sympathetic dystrophy is generally considered a disease characterized by a group of signs and symptoms including pain, swelling, and vasomotor dysfunction (vascular instability) in a limb following a minor trauma or occurring spontaneously.
		The generally accepted theory with regard to the cause of RSD is based upon an unrestricted sympathetic response, the closing of blood vessels, to an injury.
		This sympathetic response soon is replaced by a vasodilatation, the blood vessels open, to allow increased blood flow, and increased delivery of nutrients designed to hasten tissue repair.

	Reflex Sympathetic Dystrophy - Symptoms, Treatment and Prevention
		Reflex sympathetic dystrophy (RSD) is a term commonly used to describe severe pain and burning in an upper or lower limb following injury.
		In 1947, it was argued that the causalgia and related syndromes were merely manifestations of one disease entity and the all-encompassing name of reflex sympathetic dystrophy was adopted.
		The pain relief may be dramatic, with a duration outlasting the action of the anesthetic.

	Sympathetic System (Site not responding. Last check: 2007-10-20)
		Structurally, the two systems differ as to where the cell bodies of the first motor neurons are located within the spinal chord and as to what distance from the spinal chord the first motor neurons synapse with the second motor neurons.
		The cell bodies of the sympathetic system's first motor neurons lie in the thoracic and lumbar sections of the spinal chord.
		The sympathetic system often produces the "fight-or-flight" reactions in organs preparing the organism for emergency situations.

		If this is done within 10 days following the injury, the chances are almost nil of later sympathetic ophthalmia in the good eye.
		Local cortlcosteroids and atropine (and possibly systemic cortlcosteroids) may be administered immediately if sympathetic inflammation has been diagnosed.
		Untreated, sympathetic ophthalmia can progress to complete bilateral blindness over a period of months or years.

	Reflex Sympathetic Dystrophy Syndrome
		Reflex sympathetic dystrophy syndrome (RSDS), also known as complex regional pain syndrome, is a rare disorder of the sympathetic nervous system that is characterized by chronic, severe pain.
		The sympathetic nervous system is that part of the autonomic nervous system that regulates involuntary functions of the body such as increasing heart rate, constricting blood vessels, and increasing blood pressure.
		Excessive or abnormal responses of portions of the sympathetic nervous system are thought to be responsible for the pain associated with reflex sympathetic dystrophy syndrome.

	Sympathetic Division
		Some preganglionic neurones do not end in the paravertebral sympathetic ganglia but pass through to further ganglia known as the collateral ganglia which are mainly located in the abdomen close to the aorta and it's major branches.
		The post ganglionic neurones then branch off to form sympathetic nerves which serve the smooth muscles of the abdomen and the pelvic viscera and the endocrine glands found in that area.
		This is caused by the effect of the sympathetic nervous system contracting the walls of blood vessels thus narrowing the diameter and therefore allowing less blood to flow through those vessels at that time.

	sympathetic
		Agreeably suited to one's disposition or mood; congenial: sympathetic surroundings.
		As he writes, he vividly expresses a tone of sympathetic, since as a Puritan he already holds onto the belief that he is saved by God, whereas the others may suffer at the hands of God.
		As a result, he then intends to sympathize with the people, telling them that although he does not feel the same feelings as they do towards God, he does know that the others will nevertheless suffer in the end.

	Reflex Sympathetic Dystrophy (RSD) Syndrome - New York State Department of Health
		RSD is an older term used to describe one form of Complex Regional Pain Syndrome (CRPS).
		Initially, the condition was thought to be a malfunctioning of the sympathetic nervous system but researchers are questioning this theory.
		Since it is most often caused by trauma to the extremities, some conditions that can bring RSD about are sprains, fractures, surgery, damage to blood vessels or nerves and certain brain injuries.
