ep·i·neph·rine

(ĕp′ə-nĕf′rĭn)
A hormone secreted by the adrenal gland in response to physical or mental stress, as from fear. The release of epinephrine causes the heart to beat faster and more strongly, the pupils to dilate, and the rate of breathing to increase. Epinephrine also causes an increase in the amount of sugar in the blood, which can be used by the body as fuel when more alertness or greater physical effort is needed. Also called adrenaline.

epinephrine

(or adrenaline) A hormone produced by the adrenal glands to prepare the body for “fight or flight” in conditions of stress.
