Function&Application
One of the most important functions of norepinephrine is its role as the neurotransmitter released from the sympathetic neurons to affect the heart. An increase in norepinephrine from the sympathetic nervous system increases the rate of contractions in the heart.As astress hormone, norepinephrine affects parts of the brain, such as the amygdala, where attention and responses are controlled.Norepinephrine also underlies the fight-or-flight response, along with epinephrine, directly increasing heart rate, triggering the release of glucose from energy stores, and increasing blood flow toskeletal muscle.Our Advantages
