Norepinephrine is the most often used neurotransmitter by postganglionic neurons in the sympathetic nervous system. This is because the sympathetic nervous system is responsible for the fight or flight response, which requires an increase in heart rate, blood pressure, and respiratory rate. Norepinephrine facilitates these physiological changes by binding to adrenergic receptors on target organs.
