GENERAL HISTOLOGY

Detailed explanation-1: -Epinephrine is part of your sympathetic nervous system, which is part of your body’s emergency response system to danger-the “fight-or-flight” response. Medically, the flight-or-flight response is known as the acute stress response. Epinephrine is also called a catecholamine, as are norepinephrine and dopamine.

Detailed explanation-2: -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-3: -Adrenaline (epinephrine) is a hormone your adrenal glands make to help you prepare for stressful or dangerous situations. Adrenaline rush is the name for the quick release of adrenaline into your bloodstream. This gets your body ready for a “fight or flight” response.

Detailed explanation-4: -These glands respond by pumping the hormone epinephrine (also known as adrenaline) into the bloodstream. As epinephrine circulates through the body, it brings on a number of physiological changes. The heart beats faster than normal, pushing blood to the muscles, heart, and other vital organs.
