Endocrine gland
The adrenal glands are located above the kidneys in humans and in front of the kidneys in other animals. The adrenal glands produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. It controls the behaviour during crisis and emotional situations. It stimulates the heart and its conducting tissues and metabolic processes.
Adrenaline
In 1901, Jokichi Takamine patented a purified extract from the adrenal glands, and called it "adrenalin" (from the Latin "ad" and "renal", "near the kidneys"), which was trademarked by Parke, Davis & Co in the US. The British Approved Name and European Pharmacopoeia term for this drug is hence "adrenaline".
