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 anterior pituitary gland produces the following hormones and releases them into the bloodstream: 1  Adrenocorticotropic hormone, which stimulates the adrenal glands to secrete steroid hormones, principally cortisol. 2  Growth hormone, which regulates growth, metabolism and body composition.rolactin, which stimulates milk production Thyroid stimulating hormone, which stimulates the thyroid gland to secrete thyroid hormones. There are also some hormones that are produced by the hypothalamus and then stored in the posterior pituitary gland prior to being released into the bloodstream.
