from The American Heritage® Dictionary of the English Language, 4th Edition
- n. A hormone secreted by the adrenal medulla that is released into the bloodstream in response to physical or mental stress, as from fear or injury. It initiates many bodily responses, including the stimulation of heart action and an increase in blood pressure, metabolic rate, and blood glucose concentration. Also called adrenaline.
- n. A white to brownish crystalline compound, C9H13NO3, isolated from the adrenal glands of certain mammals or synthesized and used in medicine as a heart stimulant, vasoconstrictor, and bronchial relaxant.

- n. Adrenaline: a catecholamine hormone secreted by the adrenal gland in response to stress (when it stimulates the autonomic nervous system).

According to the scheme the epinephrine is attached to a receptor on the surface of the cell.
Remember that injectable epinephrine is emergency, rescue medication only.
"We jolt the heart with the paddles, we pump in epinephrine to force it to beat, so it’s taking up more oxygen."
Also, I.V. kits in case a doctor or nurse needs to start an I.V. And also, several drugs including epinephrine, which is used if someone has a severe allergic reaction, it has other uses too, and nitroglycerin for chest pain.
The study also found that epinephrine, which is the standard antidote for such allergic reactions, was under-utilized in emergency rooms.
Two, is that there are these things called epinephrine pens.
This substance he named acceleran, now known as epinephrine.4
(I referred to it in passing on page 41 when I talked about epinephrine, which is formed by the adrenal medulla.)
Each EpiPen Auto-Injector contains a single dose of a medicine called epinephrine, which you inject into your outer thigh.
Human physiology is fairly straightforward also; and when we perceive a threat to life or survival, we physiologically respond with a burst of adrenalin (a hormone more formally known as epinephrine, a catcholamine); and that compound initiates a series of biological reactions (e.g., increasing heart rate and sending more blood to the muscles) that prepare us to do one or both of the two behavioral options: run away from the danger or 'gird our loins' and fight.
