Description
Epinephrine (EPI), also known as adrenaline, is a hormone and neurotransmitter that is released in response to stress or danger. As a neurotransmitter, epinephrine acts as a chemical messenger, facilitating the transmission of nerve signals across nerve endings to other nerve cells, muscle cells, or gland cells. It plays a vital role in the "fight or flight" response, increasing heart rate, dilating airways, and mobilizing energy stores to prepare the body for action
