[edit] Biology
Endogenous substances are those that originate from within an organism, tissue or cell [1]. In biological systems endogeneity refers to the recipient of DNA (usually in prokaryotes). However, due to homeostasis, discerning between internal and external influences is often difficult.
[edit] Economics
In an economic model, an endogenous change is one that comes from inside the model and is explained by the model itself. In linear regression, any variable that appears on the left hand side is said to be endogenous.

[edit] Geology
All processes that take place inside the Earth (and other planets) are considered endogenous. They make the continents move, push the mountains up, and trigger earthquakes and vulcanism. Endogenous processes are driven by the warmth which is produced in the core of the Earth by radioactivity and gravity.
[edit] Psychology
An emotion or behaviour is endogenous if it is spontaneously generated from an individual's internal state.
