The primary stimulus for the release of growth hormone (GH) is growth hormone-releasing hormone (GHRH) produced by the hypothalamus. Additionally, factors such as sleep, exercise, stress, and low blood sugar levels can also stimulate GH release. Conversely, somatostatin inhibits its release. Overall, the regulation of GH is a complex interplay of various hormonal signals and physiological conditions.
Actions of Growth Hormone.
The growth hormone is the most important stimulus of epiphyseal plate activity, as it is responsible for stimulating the growth of bones during childhood and adolescence. It acts on the epiphyseal plates to promote bone growth and elongation.
calcium
Growth hormone is primarily released in response to low blood glucose levels, stress, exercise, sleep, and certain amino acids. Growth hormone-releasing hormone (GHRH) from the hypothalamus stimulates the pituitary gland to release growth hormone in response to these stimuli.

The Parathyroid hormone has a decrease in plasma calcium. It uses a Pentagastrin as stimulation for its release.
growth hormone
This accounts for Growth Hormone Regulatory Hormone, also called Growth Hormone Releasing Hormone, and also GRHF (for Growth Hormone Regulatory Factor). This is one of the two hypothalamic hormones (or previously named 'factors') that, respectively, stimulate or inhibit the release of growth hormone from the pituitary gland. The other hormone that inhibits the release of growth factor is called Growth Hormone Releasing-Inhibiting Hormone (or factor).
thyroid
Growth hormone stimulates the release of insulin-like growth factor 1 (IGF-1) into the blood.
Norepinephrine stimulates the release of adrenaline (epinephrine) from the adrenal medulla.
