ADRENALINE
One of the best known transmitters is the hormone epinephrine (adrenaline). When a
person is suddenly stressed or frightened, the brain instantly sends a message to the adrenal
glands, which quickly release epinephrine. Within moments, this chemical has the entire
body on alert, a response sometimes called preparation for fight or flight. The heart beats
more rapidly and powerfully, the eyes dilate to allow more light in, breathing quickens, and
the activity of the digestive system decreases to allow more blood to go to the muscles.
