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.
1 The anterior pituitary or adenohypophysis is a classical gland composed predominantly of cells that secrete protein hormones. 2  The posterior pituitary or neurohypophysis is not a separate organ, but an extension of the hypothalamus.hese hypothalamic hormones reach the anterior pituitary through the following route: 1  A branch of the hypophyseal artery ramifies into a capillary bed in the lower hypothalamus, and hypothalmic hormones destined for the anterior pituitary are secreted into that capillary blood.
