norepinephrinephenylethanolamine‐N‐methyltransferasetyrosine hydroxylaseThe catecholamines, norepinephrine and epinephrine (formerly named noradrenaline and adrenaline) are released from the adrenal gland and neurons in the brain. Norepinephrine is also released from the majority of postganglionic, sympathetic ...
Norepinephrine and epinephrine are part of a group of hormones known as catecholamines. These hormones are released by your adrenal glands, which sit above your kidneys. In some cases, they also are released from the brain as neurotransmitters. The other major member of the group isdopamine. As...

medulla as a hormone, although small amounts are produced in the nerves and act as a neurotransmitter. Noradrenaline is mainly produced in the nerves, although small amounts are also produced in the adrenal medulla. Both norepinephrine and epinephrine are released during a fight-or-flight response...
The electrodes were found to be electrochemically stable, reusable and can be used for the analysis of EP and NE in real life samples. Norepinephrine (NE) is an important catecholamine neurotransmitter in the mammalian central nervous sys- tem. It is secreted and released by the adrenal glands,...

Using the microdialysis technique in the porcine heart, we investigated whether epinephrine, taken up by and released from cardiac sympathetic nerves, can increase norepinephrine concentrations in myocardial interstitial fluid (NE(MIF)) under basal conditions and during sympathetic activation. METHODS AND ...
The sympathetic nervous system exerts its effect through two major modulators,epinephrineandnorepinephrine(Moore and Bloom 1979). Norepinephrine is the primaryneurotransmitterin the sympathetic nervous system; it is released from sympathetic nerve terminals into the circulation (Robertson 2004; Stjarne 2000)...
