GH Axis

Meaning

This refers to the Growth Hormone axis, a critical neuroendocrine pathway that involves the coordinated signaling between the hypothalamus, the pituitary gland, and the liver. The primary function is the pulsatile secretion of Growth Hormone (GH) from the pituitary, which then stimulates the production of Insulin-like Growth Factor 1 (IGF-1) in the liver. This axis is central to somatic growth, metabolic regulation, and body composition throughout the lifespan.
