Norepinephrine is made from dopamine in the medulla of the adrenal gland.
As soon as a work is "fixed in a tangible medium" that is perceptible to humans or machines
epinepherine and norepinephrine
The adrenal gland makes and secretes norepinephrine and also converts some norepinephrine into epinephrine and secretes that.
Norepinephrine is released from the sympathetic nervous system. Norepinephrine is a stress hormone which affects parts of the brain and causes the heart to beat more rapidly.
Sympathetic postganglionic neurons release norepinephrine,
Norepinephrine is made from dopamine in the medulla of the adrenal gland.
Tangible
epinephrine and norepinephrine stimulate the sympathetic nervous system
The S stands for serotonin and the N stands for norepinephrine and RI stands for reuptake inhibitor. So, obviously these drugs are supposed to work on both serotonin and norepinephrine. However, some literature uses SNRI to mean Selective Norepinephrine Reuptake Inhibitor, and this will work better on norepinephrine. Then you have the SSRI which is Selective Serotonin Reuptake Inhibitor, which works better on serotonin.
epinephrine and norepinephrine
Your case has no tangible evidence.
