Adrenaline Meaning and Definition in Wikipedia


Epinephrine, also known as adrenaline, is a hormone in the body. The Latin roots ad-+renes and the Greek roots epi-+nephros both mean into/onto the kidney, which is a reference to the adrenal glands. In medical jargon, epinephrine is shortened to just "epi" (pronounced eh-pee).

The hormone was first isolated and purified in 1901 by Japanese chemist Jokichi Takamine.
