Biology

Endogenous substances are those that originate from within an organism, tissue, or cell [1].
In some 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.

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.

Psychology

An emotion or behaviour is endogenous if it is spontaneously generated from an individual's internal state.
