Norepinephrine is a hormone secreted by certain nerve endings of the sympathetic nervous system, and by the medulla (center) of the adrenal glands. Its primary function is to help maintain a constant blood pressure by stimulating certain blood vessels to constrict when the blood pressure falls below normal.
Identification. Norepinephrine is classified as a catecholamine chemical that plays a significant role in how the body responds to stress. The body's fight-or-flight response is coordinated by both epinephrine (adrenaline) and norepinephrine (noradrenaline).However, noradrenaline is more involved with maintaining normal body functions like heart rate, blood pressure and sugar levels than responding to perceived threats.rain Processes. Norepinephrine's effects on the brain involve the areas that regulate attention, sleep, learning and emotions. When released, it stimulates the emotional and cognitive centers of the brain. When produced in normal amounts, it can create a sense of well-being, as well as euphoria.
