Norepinephrine. A catecholamine hormone secreted from the adrenal medulla and post-ganglionic adrenergic fibers in response to hypotension or emotional stress. Also: Norepinephrine

	Adrafinil As A Treatment "...Both drugs act on certain receptors, making them more susceptible to norepinephrine..." Adrenal Related Topic "...The medulla produces epinephrine and norepinephrine, which are specifically designed to help the body deal with stressful situations..." Adrenal Insufficiency Related Topic "A condition in which the adrenal gland is compromised in its production of epinephrine, norepinephrine, cortisol, corticosterone or aldosterone..." Adrenal Medulla Related Topic "The inner part of the adrenals, derived embryonically from spinal nerve precursors, they secrete epinephrine, norepinephrine and dopamine; used locally as neurotransmitters, sensitive receptors can be mobilized totally by the adrenal medullas..." Adrenoceptors Related Topic "Sites on nerve cells or fibers which react to epinephrine or norepinephrine..." Catecholamine Related Topic "Any of various amines (as epinephrine, norepinephrine, and dopamine) that function as hormones and/or neurotransmitters..." Cluster Headaches The Condition "...) The hypothalamus is also involved in the regulation of many important hormones, including serotonin, norepinephrine, and cortisol (stress hormones), melatonin (related to sleep), and beta endorphins (involved with pain)..." Depression Relationship to Manganese Requirement "...A deficiency may contribute to depression stemming from low levels of the neurotransmitters serotonin and norepinephrine..." Relationship to Vitamin B6 Requirement "B6 is a cofactor for the conversion of tryptophan to serotonin and for the synthesis of dopamine and norepinephrine..." Recommendation L-Tyrosine "Particular precursors such as tyrosine, which increases dopamine and noradrenaline, show beneficial results in the treatment of mild depression..." Recommendation L-Phenylalanine "...Phenylalanine is an important precursor for the production of noradrenaline and adrenaline thus increasing the body's ability to cope with stress..." Dopamine Related Topic "A neurohormone; precursor to norepinephrine which acts as a stimulant to the nervous system..." L-Phenylalanine As A Treatment "...L-phenylalanine can be converted to L-tyrosine and subsequently to L-dopa, norepinephrine, and epinephrine..." L-Tyrosine As A Treatment "...Tyrosine is a precursor to dopamine, noradrenaline, and adrenalin (epinephrine)..." Monoamine Oxidase Related Topic "An enzyme catalyzing the removal of an amine group from a variety of substrates, including norepinephrine and dopamine..." Phenylalanine Related Topic "...Precursor to tyrosine which is used to manufacture certain hormones (epinephrine, norepinephrine, dopa, dopamine) which are important for the transmission of nerve impulses..." Pheochromocytoma Related Topic "Encapsulated tumor of the adrenal gland secreting epinephrine and norepinephrine..." Premenstrual Syndrome PMS A (Anxiety) The Condition "...These enzymes are involved in the oxidation of biogenic amines - norepinephrine, epinephrine, dopamine, and serotonin - which have significant effects on mood and behavior..." Rhodiola rosea (Roseroot) As A Treatment "...During times of stress CRF leads a release of the catecholamines epinephrine and norepinephrine that alter blood glucose levels and serotonin synthesis..." St John's Wort As A Treatment "...When researchers measured urinary metabolites of noradrenaline and dopamine following administration of St..." Weight Loss As A Treatment "...Most of these drugs decrease appetite by affecting levels of the brain neurotransmitters catecholamine, serotonin and/or noradrenaline -- brain chemicals that affect mood and appetite..."
