endorphin
en·dor·phin E0136700 (ĕn-dôr′fĭn)n. Any of a group of peptide hormones that bind to opioid receptors and act as neurotransmitters. Endorphins reduce the sensation of pain and affect emotions.
[endo(genous) + (mo)rphin(e).]endorphin (ɛnˈdɔːfɪn) n (Biochemistry) any of a class of polypeptides, including enkephalin, occurring naturally in the brain, that bind to pain receptors and so block pain sensation[C20: from endo- + morphine]en•dor•phin (ɛnˈdɔr fɪn)
n. any of a group of peptides, resembling opiates, that are released in the body in response to stress or trauma and that react with the brain's opiate receptors to reduce the sensation of pain. [1970–75; end(ogenous) (m)orphine] en·dor·phin (ĕn-dôr′fĭn) Any of a group of substances found in the nervous system, especially in the brain, that regulate the body's response to pain and other stimuli.Did You Know? In the 1970s, scientists began to wonder why drugs like morphine could kill pain so effectively. Researchers knew that morphine attached to specific body molecules called receptors, so they reasoned that these receptors probably existed because the body itself had natural painkilling compounds that also bonded to those receptors. They searched and finally found proteins called endorphins, a word that combines endogenous, meaning "naturally occurring within the body," and morphine. When your body is under stress, it can produce endorphins so that you can still function under what would otherwise be exceptionally painful conditions. Many long-distance runners, for example, claim that after they run for a while they start to feel exceptionally happy, a condition sometimes called a runner's high. High levels of endorphins in response to the strain of running seem to be responsible for this state of mind.Thesaurus| Noun | 1. | endorphin - a neurochemical occurring naturally in the brain and having analgesic propertiespeptide - amide combining the amino group of one amino acid with the carboxyl group of another; usually obtained by partial hydrolysis of proteinneurochemical - any organic substance that occurs in neural activitybeta endorphin - an endorphin produced by the pituitary gland that suppresses painenkephalin - an endorphin having opiate qualities that occurs in the brain and spinal cord and elsewhere |

endorphin any of a class of polypeptides, including enkephalin, occurring naturally in the brain, that bind to pain receptors and so block pain sensation endorphin
endorphin [en-dor´fin] one of a group of opiate-like peptides produced naturally by the body at neural synapses at various points in the central nervous system pathways, where they modulate the transmission of pain perceptions. The term endorphin was coined by combining the words endogenous and morphine. Like morphine, endorphins raise the pain threshold and produce sedation and euphoria; the effects are blocked by naloxone, a narcotic antagonist.endorphin (ĕn-dôr′fĭn)n. Any of a group of peptide hormones that bind to opioid receptors and act as neurotransmitters. Endorphins reduce the sensation of pain and affect emotions.endorphin Physiology An endogenous opioid–eg, endorphin, leu-enkephalin, met-enkephalin, dynorphin; each binds to a cognate receptor; endorphins act as neurotransmitters and neuromodulators, they are concentrated in the brain and associated with analgesia. See Enkephalin, Neuropeptide, Neurotransmitter, POMC. en·dor·phin (ĕn-dōr'fĭn) A natural substance produced in the brain that binds to opioid receptors, thus dulling the perception of pain; postulated to trigger "exercise high," a state of euphoria and exhilaration during intense exercise. endorphin a small protein produced in the nervous system of vertebrates exhibiting actions similar to morphine.See END
