Growth Hormone Secretion

Meaning

Growth Hormone Secretion is the regulated, pulsatile release of Somatotropin (GH) from the somatotroph cells of the anterior pituitary gland into the peripheral circulation. This hormone plays a pivotal role in mediating somatic growth during development and maintaining metabolic balance, including lipolysis and protein synthesis, in adulthood. The timing and amplitude of these secretory events are tightly controlled by hypothalamic input. Optimal secretion profiles are critical for tissue anabolism and regenerative capacity.
