Adrenal Axis

Meaning

The Adrenal Axis, formally known as the Hypothalamic-Pituitary-Adrenal (HPA) axis, is a crucial neuroendocrine system responsible for regulating the body’s stress response. It represents a complex feedback loop connecting the central nervous system and the endocrine system, governing the release of cortisol and other adrenal hormones. This intricate communication pathway maintains homeostasis and influences mood, immunity, metabolism, and energy levels. Understanding the HPA axis is fundamental to clinical practice in hormonal health.
