Regulation of Hormone Secretion & Feedback Control

Hormones help in maintaining internal environment of body constant. Keeping internal environment of body constant is called homeostasis. The quantity of hormone secreted is regulated according to the need of the body. Control of hormones is by two mechanisms

  1. Feed back control

  2. Neural control.

Feedback control generally high blood concentration of any hormone inhibits its further secretion and low concentration stimulates its secretion. Thus Feed back control can be

  • Negative feedback control; most of the control mechanisms operate by this mechanism, if the level of hormone is more, it acts over the hypothalamus and pituitary to inhibit its… (374 more words) …
