Endorphins (contracted from endogenous morphine) [1] [2] [3] are peptides produced in the brain that block the perception of pain and increase feelings of wellbeing. They are produced and stored in the pituitary gland of the brain. Endorphins are endogenous painkillers often produced in the brain and adrenal medulla during physical exercise or ...
Global function of β-endorphin is related to decreasing bodily stress and maintaining homeostasis resulting in pain management, reward effects, and behavioral stability. β-Endorphin in global pathways diffuse to different parts of the body through cerebral spinal fluid in the spinal cord, allowing for β-endorphin release to affect the ...
Endorphins are generally known as neurotransmitters that are released when the body goes into pain. [3] The three endorphins that play a role in this response are α-endorphin, β-endorphin ( beta -endorphin), and γ-endorphin ( gamma -endorphin) which are all derived from the same polypeptide known as pro-opiomelanocortin .

Most people just think of men when they hear testosterone, but the primary male sex hormone is produced in women too (in the ovaries, in fact) and it turns out that more of it is released ...
The enkephalins are termed endogenous ligands, as they are internally derived (and therefore endogenous) and bind as ligands to the body's opioid receptors. Discovered in 1975, two forms of enkephalin have been found, one containing leucine ("leu"), and the other containing methionine ("met"). Both are products of the proenkephalin gene. [2]
[2] The release of dopamine from the mesolimbic pathway into the nucleus accumbens regulates incentive salience (e.g. motivation and desire for rewarding stimuli ) and facilitates reinforcement and reward-related motor function learning; [ 3 ] [ 4 ] [ 5 ] it may also play a role in the subjective perception of pleasure .
Peptides and amines released by PNEC are involved in normal fetal lung development including branching morphogenesis. The best-characterized peptides are GRP, the mammalian form of bombesin, and CGRP; these substances exert direct mitogenic effects on epithelial cells and exhibit many properties akin to growth factors.
A neurohormone is any hormone produced and released by neuroendocrine cells (also called neurosecretory cells) into the blood. [1] [2] By definition of being hormones, they are secreted into the circulation for systemic effect, but they can also have a role of neurotransmitter or other roles such as autocrine (self) or paracrine (local) messenger.
