</html><description>Naturally occurring opioid peptides within the body.Substances, produced naturally by the brain and by other tissues that modulate pain sensitivity. Their collective name indicates their similarity to the opiates (morphine, codeine, heroin) produced from plants such as the opium poppy, which bind to the same molecular receptors in the brain that are the targets of the endogenous opioids. They also fulfill other functions.</description></oembed>
