### organic neurochemical:

Endorphin
* More endorphins are released in the pituitary gland during times of pain or stress.
* act as pain inhibitors, which block the pain signal throughout the body
  - like morphine and are the body's natural painkillers
  - on several areas the brain, particularly the hypothalamus and the limbic system
* also appear to share with morphine a potential for addiction or tolerance
  - circulate after exercise and other times of pleasure and satisfaction
  - play a role in the body's ability to regulate temperature
* also reduce pain and induce sexual feelings
  - strengthen the immune system
* are a group of proteins made naturally in the brain that help people endure pain
  - substances formed within the body that naturally relieve pain
  - a. small molecule transmitters
  - addictive, especially over time
  - another of the chemicals which are thought to produce the feel good factor
  - chemical compounds designed to act much as does any pain killer such as morphine
  - chemicals that have strong painkilling effects in humans
  - endogenous morphine- natural painkillers
  - hundreds or even thousands of times more potent than morphine on a molar basis
  - like morphine and can be addictive
  - morphine-like substances in the brain that relieve feelings of stress and pain
* are natural chemicals created in the body, which are involved in pain tolerance
  - that seem to act like antidepressants
  - opiate-like chemicals produced by the brain
* are natural opiates of the brain
  - released by the brain to signal pleasure rather than pain
* are natural pain killers in the body
  - relievers produced by the body
* are natural painkillers and also appear to affect behaviour
  - substances in the body that increase one s sense of well-being
  - naturally-occurring opioids
  - neuromodulators in that they can effect the rate at which nerves fire
* are neurotransmitters that attach to the same receptors in our brains as the opiates
  - relieve pain and induce euphoria
  - one of the body's many pain relief chemicals
  - pain killers that are normally produced by the body in response to pain
  - pain-killers
  - pain-killing chemicals that occur naturally in the brain
  - part of the body's natural pain-control network
  - peptides
  - significantly less potent than morphine narcotic
  - small-chain peptides that activate our endogenous opiate receptors
  - substances in the brain that relieves feelings of stress and pain
  - the body s natural painkillers and evoke feelings of well-being, even euphoria
* are the body's feel-good hormones that give moods a natural lift
  - internal pain regulators
* are the body's natural morphine-like chemicals
  - relaxant and pain reliever
* are the body's own natural defenses against pain
  - pain relievers
  - brain's natural painkillers and also metabolize into serotonin
  - natural sedatives of the body, and have a calming effect on the horse
  - valuable substances which are naturally produced by our body
* can further decompose to small fragments, oligomers, which are still active
  - help reduce pain
* contribute to the runner s high and diminishes pain levels.
* create feelings of pleasure and joy, and of euphoria
  - hallucinations
* effect the dopamine pathway that feeds into the frontal lobe.
* have a morphine-like effect and are sometimes referred to as the body's own opiates
  - less ability to reduce pain when serotonin is low
* help to improve the circulation of blood..
* play a role in regulating temperature, intestinal function, and appetite
  - the system which produces sensations of pain and pleasure
* probably contribute to the warm inner glow induced in susceptible chocaholics.
* produce calming, soothing effects.
* reduce the sensation of pain and affect emotions.
+ Endorphin, Types: Endocrine system :: Proteins
  * They are usually in the hypothalamus and pituitary gland. More endorphins are released in the pituitary gland during times of pain or stress. Exercise increases the endorphin release too. For the same reason, exercise results in a better mood.
