What is the Origin of Endogenous Hormone Set Points?

This terminology is rooted in control systems theory applied to endocrinology, where the concept of a 'set point' dictates the desired state for any regulated variable, much like a thermostat setting. In human physiology, these points are established during development and refined by factors such as age, genetics, and chronic environmental exposures. They define the boundaries of healthy physiological operation.

What is the Mechanism of Endogenous Hormone Set Points?

The set points function as the comparator mechanism within the endocrine feedback system. When a measured hormone level deviates below or above this predetermined range, the central nervous system or pituitary gland initiates compensatory signaling—releasing or inhibiting releasing hormones or tropic hormones. This action drives the peripheral gland activity back toward the established set point, ensuring metabolic and reproductive stability across the lifespan.

Endogenous Hormone Set Points

Meaning

Endogenous Hormone Set Points represent the genetically and developmentally determined target ranges within which the body’s regulatory systems strive to maintain circulating levels of specific hormones. These set points are dynamic yet tightly controlled by complex feedback loops involving the hypothalamus, pituitary, and peripheral glands. Deviations from these intrinsic reference ranges often manifest as clinical pathology.
