Final answer:
Growth hormone (GH) is the anterior pituitary hormone that is inhibited by hypothalamic Somatostatin, also known as growth hormone-inhibiting hormone (GHIH).
Step-by-step explanation:
The anterior pituitary hormone that is inhibited by hypothalamic Somatostatin is Growth hormone (GH). The hypothalamus produces a variety of regulatory hormones that control the secretion of anterior pituitary hormones. Somatostatin, also known as growth hormone-inhibiting hormone (GHIH), specifically inhibits the release of growth hormone from the anterior pituitary.
