MEDICAL PHYSIOLOGY

Detailed explanation-1: -Norepinephrine (Noradrenaline) Norepinephrine, also known as noradrenaline, is both a neurotransmitter and a hormone. It plays an important role in your body’s “fight-or-flight” response.

Detailed explanation-2: -About Norepinephrine When working alongside adrenaline, norepinephrine supports the fight-or-flight response by increasing your heart rate, breaking down fat, and increasing glucose levels. It gives your brain and body the energy it needs to take action.

Detailed explanation-3: -First identified in the 1940s by Swedish physiologist Ulf von Euler, norepinephrine, also known as noradrenaline, is a neurotransmitter of the brain that plays an essential role in the regulation of arousal, attention, cognitive function, and stress reactions.

Detailed explanation-4: -Catecholamines are the primary mediators of the fight-or-flight response. Norepinephrine is the major neurotransmitter in the peripheral sympathetic nervous system, whereas epinephrine is the primary hormone secreted by the adrenal medulla. The release of both is increased during stress.
