Adrenaline crystals (polarized light micrographs). Adrenaline, also called epinephrine, is normally present in blood in small quantities. It is a hormone produced in the adrenal glands above the kidneys. The glands are controlled by the hypothalamus, the part of the brain responsible for instinct and emotion. In times of stress, more adrenaline is secreted into the bloodstream. It widens the airways of the lungs and constricts small blood vessels. This makes the muscles work harder and produces a "fight or flight" response. Adrenaline used as a drug expands the bronchioles in acute asthma attacks and stimulates the heart in cases of anaphylactic shock.
