- In biology endogenous substances are those that originate from within an organism, tissue or cell [1]. In biological systems endogeneity (biology) refers to recipient of DNA (usually in prokaryotes). However, due to homeostasis, discerning between internal and external influences is often difficult.
- In an economic model, an endogenous change is one that comes from inside the model and is explained by the model itself.
- In geology the word endogenous refers to all processes that take place inside the Earth and all other planets. They make the continents move, push the mountains up, trigger earthquakes and vulcanism. 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.
