Noradrenergic Cell Groups

	Noradrenergic Cell Groups Noradrenergic cell groups refers to collections of neurons in the central nervous system that have been demonstrated by histochemical fluorescence to contain the neurotransmitter norepinephrine (noradrenalin). They are named * Noradrenergic cell group A1 * Noradrenergic cell group A2 * Noradrenergic cell group A4 * Noradrenergic cell group A5 * Noradrenergic cell group A6 * Noradrenergic cell group A7 Noradrenergic cell group A7 is a group of cells fluorescent for norepinephrine that is located in the pontine reticular formation ventral to the superior cerebellar peduncle of the pons The pons (from Latin , "bridge") is part of the brains ... * Noradrenergic cell group A6sc * Noradrenergic cell group Acg See also * Adrenergic cell groups References External links * More information aBrainInfo Norepinephrine {{neuroanatomy-stub ...

picture info	Norepinephrine Norepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic chemical in the catecholamine family that functions in the brain and body as both a hormone and neurotransmitter. The name "noradrenaline" (from Latin '' ad'', "near", and '' ren'', "kidney") is more commonly used in the United Kingdom, whereas "norepinephrine" (from Ancient Greek ἐπῐ́ (''epí''), "upon", and νεφρός (''nephrós''), "kidney") is usually preferred in the United States. "Norepinephrine" is also the international nonproprietary name given to the drug. Regardless of which name is used for the substance itself, parts of the body that produce or are affected by it are referred to as noradrenergic. The general function of norepinephrine is to mobilize the brain and body for action. Norepinephrine release is lowest during sleep, rises during wakefulness, and reaches much higher levels during situations of stress or danger, in the so-called fight-or-flight response. In the ...

	Noradrenergic Cell Group A1 Noradrenergic cell group A1 is a group of cells in the vicinity of the lateral reticular nucleus of the medullary reticular formation that label for norepinephrine in primates and rodents. They are found in the ventrolateral medulla The ventrolateral medulla, part of the medulla oblongata of the brainstem, plays a major role in regulating arterial blood pressure and breathing. It regulates blood pressure by regulating the activity of the sympathetic nerves that target the hear ... in conjunction with the adrenergic cell group C1.

	Noradrenergic Cell Group A2 Noradrenergic cell group A2 is a group of cells in the vicinity of the dorsal motor nucleus of the vagus nerve in the medulla that label for norepinephrine Norepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic chemical in the catecholamine family that functions in the brain and body as both a hormone and neurotransmitter.

	Noradrenergic Cell Group A4 Noradrenergic cell group A4 is a group of cells exhibiting noradrenergic fluorescence that, in the rat, are located in the Tegmen ventriculi quarti (roof of the fourth ventricle) ventral to the cerebellar nuclei, and in the macaque, are found at the edge of the lateral recess of the fourth ventricle The fourth ventricle is one of the four connected fluid-filled cavities within the human brain. These cavities, known collectively as the ventricular system, consist of the left and right lateral ventricles, the third ventricle, and the fourth ve ... caudally, extending to beneath the floor of the ventricle where they merge with the noradrenergic group A6, the locus ceruleus.

	Noradrenergic Cell Group A5 Noradrenergic cell group A5 is a group of cells in the vicinity of the superior olivary complex in the pontine tegmentum Pontine may refer to: * Having to do with the pons, a structure located in the brain stem (from ''pons'', "bridge") * Pontine Marshes, a region of Italy near Rome * Pontine Islands The Pontine Islands (, also ; it, Isole Ponziane ) are an ar ... that label for norepinephine in primates, rodents and other mammals. The noradrenergic A5 pontine cell group receives inputs from the hypothalamus and several brainstem areas extending from the midbrain to the medulla. It has reciprocal connections with these areas. Its major output is to the spinal cord. These anatomical connections suggest a role in autonomic regulation and A5 has been implicated in control of heart rate, blood pressure and respiration. It may also be involved in modulation of pain as part of the descending mesencephalic to spinal cord system.Pertovaara, Antti. "Noradrenergic pain modulation." P ...

	Adrenergic Cell Groups Adrenergic cell groups refers to collections of neurons in the central nervous system that stain for PNMT, the enzyme that converts norepinephrine to epinephrine (adrenaline). Thus, it is postulated that the neurotransmitter they produce may be epinephrine (adrenaline). Located in the medulla, they are named adrenergic cell group C1, adrenergic cell group C2, and adrenergic cell group C3.
