Illustration of adrenaline (epinephrine). Adrenaline is a hormone produced in the adrenal medulla and also functions as a neurotransmitter in the central nervous system. As a (stress) hormone, adrenaline increases heart rate, raises blood pressure by contracting blood vessels, dilates bronchioles and releases sugar from the liver to supply muscles with energy more quickly. | |
