The term endorphin implies a pharmacological activity (analogous to the activity of the corticosteroid category of biochemicals) as opposed to a specific chemical formulation. It consists of two parts: endo- and -orphin; these are short forms of the words endogenous and morphine, intended to mean "a morphine-like substance originating from within the body. Endorphins are the human body's natural morphine,that are stimulated in response to pain. In chronic pain disorders it is thought that there is a lack of these endogenous chemicals.
