What is the Origin of Hormonal Feedback Regulation?

This is a core concept in endocrinology, derived from the study of homeostatic control systems in biological regulation. The term describes the cyclical, closed-loop communication between the hypothalamus, pituitary, and peripheral glands. Regulation signifies the active maintenance of a set point.

What is the Mechanism of Hormonal Feedback Regulation?

Negative feedback, the most common form, involves elevated circulating hormone levels binding to receptors on the hypothalamus or pituitary, signaling them to decrease releasing hormone or tropic hormone output. For example, high cortisol inhibits the release of ACTH and CRH. This dampening effect ensures that the endocrine system remains responsive to immediate physiological needs without overshooting the required concentration.

Hormonal Feedback Regulation

Meaning

The intricate physiological mechanism where the concentration of a final hormone product influences the secretion rate of the upstream endocrine glands responsible for its production. This self-regulating system maintains hormonal homeostasis, preventing excessive or deficient signaling. Both negative and positive feedback loops are crucial components of this governance.
