Which one of the following glands produces the Growth Hormone (Somatotropin) ?
Explanation
Growth Hormone (GH), also known as somatotropin, is primarily produced and secreted by the pituitary gland, specifically by the somatotroph cells in the anterior pituitary [t1][t3]. The hypothalamus regulates this process by releasing Growth Hormone-Releasing Hormone (GHRH) to stimulate secretion or somatostatin to inhibit it [c1][t2]. While other glands mentioned have distinct roles—the adrenal glands produce cortisol and adrenaline, the pancreas secretes insulin and glucagon, and the thyroid produces thyroxine—none of these are the source of somatotropin [t2][t6]. Somatotropin is essential for controlling skeletal growth, protein synthesis, and fat metabolism [t5][t8]. It acts both directly on tissues and indirectly by stimulating the liver to produce insulin-like growth factors (IGFs) [t1][t8]. Therefore, the pituitary gland is the correct site of production for this hormone.
