The hypothalamus produces hormones and other factors that regulate production of hormones by the anterior pituitary gland. The thyroid gland is part of the hypothalamic-pituitary-thyroid axis, and control of thyroid hormone secretion is exerted by classical negative feedback, as depicted in the diagram. Cytokines also modify this neuroendocrine axis. The hypothalamus–pituitary complex can be thought of as the “command center” of the endocrine system. The posterior pituitary gland does not produce hormones, but rather stores and secretes hormones produced by the hypothalamus. The pituitary gland itself consists of a larger anterior lobe that makes the following hormones: adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), growth hormone (GH) and Prolactin . The paraventricular nuclei produce the hormone oxytocin, whereas the supraoptic nuclei produce ADH. Parts of Pituitary gland. The pituitary gland is called the "Master Gland" because it directs a multitude of endocrine functions in the body.It regulates hormone activity in other endocrine glands and organs. The unstained cells in the image are those that secrete the other pituitary hormones. These hormones travel along the axons into axon terminals within the posterior pituitary. A final point to be made is that individual cells within the anterior pituitary secrete a single hormone (or possibly two in some cases).
