PATHOLOGY

Detailed explanation-1: -Epinephrine (also called adrenaline), norepinephrine, and dopamine make up a small but important hormone family called catecholamines. Epinephrine and norepinephrine are the hormones behind your “fight-or-flight” response (also called the fight, flight, or freeze response).

Detailed explanation-2: -Adrenaline is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for ‘fight or flight’.

Detailed explanation-3: -Epinephrine and norepinephrine are similar chemicals that act as both neurotransmitters and hormones in the body. Both substances play an important role in the body’s fight or flight response, and their release into the bloodstream causes increases in blood pressure, heart rate, and blood sugar levels.

Detailed explanation-4: -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.
