GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -When you’re scared or stressed suddenly, adrenaline is quickly sent into your body. This is commonly known as an adrenaline rush because it happens so fast. You’ve probably heard of “fight or flight.” Adrenaline is what gets your body ready to fight or flee danger.

Detailed explanation-3: -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.
