  Endogenous - Wikipedia, the free encyclopedia
In an economic model, an endogenous change is one that comes from inside the model and is explained by the model itself.
Endogenous processes are driven by the warmth which is produced in the core of the Earth by radioactivity and gravity.
In psychology an emotion or behaviour is endogenous if it is spontaneously generated from an individual's internal state.

 Endogenous retrovirus - Wikipedia, the free encyclopedia
Endogenous retroviruses are retroviruses thought to be derived from ancient infections of germ cells in humans and mammals; as such their proviruses are passed on to the next generation and as such now remain in the genome.
Human endogenous retroviruses (HERVs) are suspected of involvement in some autoimmune diseases, in particular with multiple sclerosis.

 Miller: Endogenous Opioids   (Site not responding. Last check: 2007-11-07)
Endorphins were named by combining the words endogenous and morphine (2) and their discovery occurred when a substance exhibiting the analgesic characteristics of morphine was extracted from the brain.
The latter pathway is vital to the understanding of the actions of endogenous opioids because the areas along the pathway are rich in opioid peptides and opioid receptors, and serotonin induces the release of opioid peptides.
The most popular action of endogenous opioids is their creation of a feeling of euphoria during exercise, which endurance athletes frequently refer to as "runner's high." Numerous investigators have observed an increase in blood plasma levels of beta-endorphin following physical activity (14).

 Neuropharmacology of Endogenous Opioid Peptides
The distinction between the effects of exogenously applied opioids and effects of endogenously released opioid peptides is important, because it is not necessarily true that a given population of receptors occupied by bath-applied drug are relevant targets for opioid peptides released from endogenous stores.
Thus endogenous dynorphin modulation of synaptic activity in the dentate gyrus region may have a prominent role in the pathological and physiological function of the hippocampus.
The endogenous opioids do not appear to be implicated in procedural memory (i.e., "learning how" to navigate the maze efficiently), but they do alter declarative memory (i.e., "learning where" the reward is) for a given trial.

Endogenous retroviruses (ERVs) are vestiges of ancestral viral infection that have been incorporated into a host's genome.
Abstract:The genomes of modern humans are riddled with thousands of endogenous retroviruses (HERVs), the proviral remnants of ancient viral infections of the primate lineage.
Endogenous retroviruses (ERVs) provide phylogenetic information in two ways: (i) by comparison of integration site polymorphism and (ii) by orthologous comparison of evolving, proviral, nucleotide sequence.
