What is the Origin of Endorphin Response System?

The term "endorphin" is a contraction of "endogenous morphine," coined in the 1970s following the discovery of endogenous substances that could bind to the same brain receptors as opiate drugs. The discovery of these internal opioids confirmed the existence of a dedicated system for natural pain control and pleasure, which evolved to reinforce behaviors essential for survival, such as eating and reproduction.

What is the Mechanism of Endorphin Response System?

Endorphins are synthesized from precursor proteins like proopiomelanocortin (POMC) and are released from the pituitary gland and hypothalamus. They act by binding to opioid receptors, particularly the mu-opioid receptors, which are distributed throughout the central and peripheral nervous systems. This binding event inhibits the release of neurotransmitters, such as Substance P, that transmit pain signals, thereby effectively blocking the pain pathway and simultaneously activating reward circuits.

Endorphin Response System

Meaning

The Endorphin Response System refers to the body’s intrinsic neurobiological network responsible for the production and release of endorphins, which are endogenous opioid peptides. This system functions as the body’s natural analgesic and reward mechanism, primarily released in response to pain, stress, vigorous exercise, or pleasurable stimuli. It plays a critical role in stress resilience, mood elevation, and dampening the perception of physical discomfort.
