The image below represents the hGH hormonal axis that exists in the human body. Notice that arrows represent activation (or stimulation) of tissues, while the blunt ends represent inhibition of tissues. GHRH = growth hormone releasing hormone, SS = somatostatin, GH = growth hormone, AA = amino acid, IGF-1 = insulin-like growth factor
16 paź 2019 · Regulation of growth hormone (GH) gene expression and secretion during pregnancy and lactation in the rat: role of insulin-like growth factor-I, somatostatin, and GH-releasing hormone.
8 lut 2024 · Growth hormone, either directly or indirectly, affects almost every tissue in the body, especially skeletal muscle and cartilage cells (chondrocytes). The overall effects, arising from an interplay between GH and IGF-1, are important for the following: Skeletal growth. Muscle strength.
Triggers ovulation and development of the corpus luteum and the production of progesterone. Triggers testosterone production. Triggers growth of ovarian follicles. Triggers sperm production. Affects uterine contractions in pregnancy and birth and stimulate the release of breast milk.
26 kwi 2018 · This document provides an overview of growth hormones including: - Their structure, synthesis in the pituitary gland, regulation by hypothalamic hormones, and actions in the body. - Growth hormones are released in a pulsatile fashion and stimulate growth and metabolism.
28 gru 2021 · Growth hormone (GH), produced by the anterior pituitary, accelerates the rate of protein synthesis, particularly in skeletal muscles and bones. Growth hormone has direct and indirect mechanisms of action.
Growth hormone-releasing hormone (GHRH) and somatostatin (GHIH) are two important hormones that regulate the release of GH from the pituitary gland. Additionally, factors such as sleep, exercise, stress, and nutrition can also influence GH secretion.
