Which one of the following glands produces the Growth Hormone (Somatotropin) ?
Explanation
Growth hormone (GH), also known as somatotropin, is a peptide hormone synthesized and secreted by the somatotrophs of the anterior pituitary gland [t2][t9]. The pituitary gland, often referred to as the 'master gland', is located at the base of the brain and produces several hormones that regulate growth and other endocrine functions [t1][t6]. The secretion of somatotropin is primarily controlled by the hypothalamus, which releases growth hormone-releasing hormone (GHRH) to stimulate production and somatostatin to inhibit it [c1][t9]. While other glands like the thyroid produce thyroxine for metabolism [c1][t4], and the adrenal glands produce adrenaline and cortisol [t1], it is specifically the anterior lobe of the pituitary gland that is responsible for producing the growth hormone necessary for the development of tissues, bones, and muscles [t7][t8].
