In the most basic terms, the 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 what has been called the fight-or-flight response.n the sympathetic nervous system norepinephrine is used as a neurotransmitter by sympathetic ganglia located near the spinal cord or in the abdomen, and is also released directly into the bloodstream by the adrenal glands.
Norepinephrine. In addition to epinephrine, we see norepinephrine, which is a second hormone secreted by the adrenal medulla that increases heart rate, blood pressure, cardiac output and blood glucose levels.So we see that norepinephrine is very similar to epinephrine.t the center of the adrenal glands we see the adrenal medulla. This portion of the gland is stimulated by the sympathetic nervous system to secrete catecholamines, which are hormones that help you deal with short-term stress. There are two catecholamines. One is called epinephrine or adrenaline.
