Annyeong friend!
********************************************************************************************
Feedback loops are used extensively to regulate secretion of hormones in the hypothalamic-pituitary axis. ... When blood concentrations of thyroid hormones increase above a certain threshold, TRH-secreting neurons in the hypothalamus are inhibited and stop secreting TRH.

The feedback mechanism regulates the timing and amount of hormone to be secreted.
Feedback means that some element in the physiological response to a hormone feeds back to the endocrine gland either directly or indirectly and effects its secretion rate. The feedback may be negative or positive.
For example
1) insulin regulates the amount of blood glucose. When the level of blood glucose is high, insulin secretion is turned on by the pancreas which acts on target tissues like liver to convert excess sugar into glycogen. When the blood glucose concentration is normal the insulin secretion is stopped.
2) if a person has more sugar in his blood, it is detected by the cells of the pancreas. As a result, more insulin will be secreted to oxidise the sugar. As blood sugar level falls, insulin secretion is reduced.
