How does endorphin differs from adrenalin?

Adrenalin drives you to do something... it pushes you to your limits. Endorphins tries to relax you when your energies were driven to its limits. Adrenalin gives you the feeling of runner's high. While endorphin triggers that feeling of bliss... almost similar.

"Runner's high" redirects here. For the album by The Pillows, see Runners High.

For other uses, see Endorphin (disambiguation).

Endorphins (or more correctly Endomorphines) are endogenous opioid biochemical compounds. They are peptides produced by the pituitary gland and the hypothalamus in vertebrates, and they resemble the opiates in their abilities to produce analgesia and a sense of well-being. In other words, they might work as "natural pain killers." Using drugs may increase the effects of the endorphins.

The term "endorphin" implies a pharmacological activity (analogous to the activity of the corticosteroid category of biochemicals) as opposed to a specific chemical formulation.

The term endorphin rush has been adopted in popular speech to refer to feelings of exhilaration brought on by pain or danger, supposedly due to the influence of endorphins, although this term does not occur in the medical literature.

Adrenalin (lat of. ad "too" and ren "kidney"; also Epinephrin (INN)) is mentioned in suprarenal body Mark formed and in stress situations hormone paid in the blood. As stress hormone adrenalin arranges an increase of the heart frequency, a rise of the blood pressure, an extension of the bronchi, a fast supply of energy reserves by fat dismantling (lipolyse) as well as a release and a biosynthesis of glucose. It adjusts likewise the blood circulation (centralization) and the stomach-intestineactivity (inhibition). In the central nervous system adrenalin occurs as neurotransmitter in adrenergen neurons . Its effects arrange adrenalin over an activation of g-protein-coupled receptors, for the Adrenozeptoren.

Basically the body releases adrenalin when under stress (flight or fight) and endorphins to combat pain and make us feel better. (runner's high) Adrenalin occurs in nervous system and endorphins originate in pitutary gland and hypothalamus. One helps us in times of emergency and the other in times of pain. Both essential to our well being.

Hope this helps a little.

endorphin is an exhilaration from fear (usually) and adrenaline is a heightened pulse rate due to excitement (usually), so they are almost the same thing
