1 When blood concentrations of thyroid hormones increase above a certain threshold, TRH-secreting neurons in the hypothalamus are inhibited and stop secreting TRH. 2  This is an example of negative feedback.
The rate of hormone biosynthesis and secretion is often regulated by a homeostatic negative feedback control mechanism. Such a mechanism depends on factors that influence the metabolism and excretion of hormones.Thus, higher hormone concentration alone cannot trigger the negative feedback mechanism.he rate of hormone biosynthesis and secretion is often regulated by a homeostatic negative feedback control mechanism.
