Overview of Hypothalamic and Pituitary Hormones. The pituitary gland is often portrayed as the master gland of the body. Such praise is justified in the sense that the anterior and posterior pituitary secrete a battery of hormones that collectively influence all cells and affect virtually all physiologic processes. The pituitary gland may be king, but the power behind the throne is clearly the hypothalamus.
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.
