A. Growth Hormone-Releasing Hormone (GHRH) and Somatostatin

The release of hormones by the pituitary gland is regulated by releasing hormones and inhibiting hormones produced by the hypothalamus.
Specifically, the growth hormone-releasing hormone (GHRH) stimulates the release of growth hormone (GH) from the pituitary, while somatostatin inhibits its release.
