Epinephrine is not only a hormone, but it is also one of the important neurotransmitters that is used by the nervous system to send messages to other nerves and muscle tissue.

Epinephrine the hormone, is produced by the adrenal glands when the body is faced with a stressful (or even life-threatening) situation that causes them to either stand and fight or get away - this is called the "flight or flight" response, which is the way humans react when they are frightened and possibly in danger.

Epinephrine causes blood pressure to raise, the heart rate to beat faster, increased metabolism and blood glucose levels, increased energy production and blood flow to the extremeties is also increased.
