negative feedback loop


Show Summary Details

Quick Reference

A physiological loop for the control of hormone production by a gland. High levels of a circulating hormone act to reduce production of the releasing factors triggering its own production, i.e. they have a negative feedback on these trigger factors. As circulating levels of the hormone fall, the negative feedback is reduced and the releasing factor starts to be produced again, allowing the hormone level to rise again.
