'corticotropin' originates from 'Latin', specifically the word 'cortex', where 'cortex' meant 'bark' or 'rind', and 'tropin' from Greek 'tropos', meaning 'turn' or 'change'.

'corticotropin' changed from the Latin word 'cortex' and Greek 'tropos' and eventually became the modern English word 'corticotropin'.

Initially, it meant 'a substance affecting the cortex', but over time it evolved into its current meaning of 'a hormone stimulating the adrenal cortex'.
