Endocrine Command Chain

Meaning

The Endocrine Command Chain is a conceptual term representing the hierarchical and interconnected network of glands and hormones that govern physiological function, most notably the Hypothalamic-Pituitary-Axis (HPA, HPT, HPG). This chain describes the sequential communication that begins with the brain’s signaling centers, progresses through the pituitary gland, and culminates in the target endocrine organs like the thyroid, adrenals, or gonads. Maintaining synchronized communication within this chain is paramount for systemic homeostasis, as a disruption at any level can cascade into widespread hormonal imbalance.
