adrenaline: [20] The hormone adrenaline is secreted by glands just above the kidneys. From their position these are called the ‘adrenal glands’ [19], a term based on Latin rēnes ‘kidney’, which has also given English renal [17] and (via Old French) the now obsolete reins ‘kidneys’ [14]. The discovery of adrenaline and the coining of its name are both disputed: they may have been the work of Dr Jokichi Takamine or of Dr Norton L. Wilson. [adrenaline etymology, adrenaline origin, 英语词源]
