Epinephrine is a hormone produced by the adrenal medulla that helps regulate heart rate, blood pressure, and other metabolic functions. It is also known as adrenaline and is chemically similar to the neurotransmitter norepinephrine. Epinephrine plays an important role in the body's fight or flight response and is released during times of stress.
