Growth Hormone (Somatotropin) Growth hormone is a protein hormone of about 190 amino acids that is synthesized and secreted by cells called somatotrophs in the anterior pituitary. It is a major participant in control of several complex physiologic processes, including growth and metabolism.
The pituitary gland is divided into two lobes, an anterior (or front) lobe and a posterior (rear) lobe. The anterior lobe of the pituitary gland is stimulated by releasing hormones that are produced in the hypothalamus. The releasing hormones stimulate the anterior pituitary to release tropic hormones.he hypothalamus secretes hormones into this portal system and the hormones act on the anterior pituitary to trigger the synthesis/secretion of pituitary hormones. The other is a direct anatomical connection between the hypothalamus and the posterior pituitary gland.
