  2. Hypothalamic–pituitary hormone - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic–pituitary...

    It is possible for the function of these hormones to be altered by physical activity. [2] In posterior pituitary we have hormones that control absorption of water and oxytocin. Anterior hypophysis, neurosecretory cells which release hormones. There is a pituitary portal system, with which the hormones are transported.

  3. Hypothalamus - Wikipedia

    en.wikipedia.org/wiki/Hypothalamus

    The hypothalamus has a central neuroendocrine function, most notably by its control of the anterior pituitary, which in turn regulates various endocrine glands and organs. Releasing hormones (also called releasing factors) are produced in hypothalamic nuclei then transported along axons to either the median eminence or the posterior pituitary ...

  4. Neuroendocrinology - Wikipedia

    en.wikipedia.org/wiki/Neuroendocrinology

    Hypothalamic interaction with the posterior and anterior pituitary glands. The hypothalamus produces the hormones oxytocin and vasopressin in its endocrine cells (left). These are released at nerve endings in the posterior pituitary gland and then secreted into the systemic circulation.

  5. Endocrine system - Wikipedia

    en.wikipedia.org/wiki/Endocrine_system

    The hypothalamus, pancreas, and thymus also function as endocrine glands, among other functions. (The hypothalamus and pituitary glands are organs of the neuroendocrine system . One of the most important functions of the hypothalamus—it is located in the brain adjacent to the pituitary gland—is to link the endocrine system to the nervous ...

  6. Endocrine gland - Wikipedia

    en.wikipedia.org/wiki/Endocrine_gland

    The hypothalamus regulates the hormonal output of the anterior pituitary and creates two hormones that it exports to the posterior pituitary for storage and later release. Four of the six anterior pituitary hormones are tropic hormones that regulate the function of other endocrine organs. Most anterior pituitary hormones exhibit a diurnal ...

  7. Hypothalamic–pituitary–gonadal axis - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic–pituitary...

    HPG regulation in males, with the inhibin/activin system playing a similar role on GnRH-producing cells. The hypothalamus is located in the brain and secretes GnRH. [1] GnRH travels down the anterior portion of the pituitary via the hypophyseal portal system and binds to receptors on the secretory cells of the adenohypophysis. [2]

  8. Hypophyseal portal system - Wikipedia

    en.wikipedia.org/wiki/Hypophyseal_portal_system

    Its main function is to quickly transport and exchange hormones between the hypothalamus arcuate nucleus and anterior pituitary gland. The capillaries in the portal system are fenestrated (have many small channels with high vascular permeability ) which allows a rapid exchange between the hypothalamus and the pituitary.

  9. Pituitary gland - Wikipedia

    en.wikipedia.org/wiki/Pituitary_gland

    Specialized cells from the hypothalamus, known as pituicytes, migrate to the posterior pituitary, where they help store and release hormones such as oxytocin and vasopressin. 3. Hormone Production and Functional Maturity By around the 12th to 16th week of gestation, the anterior pituitary begins producing hormones like growth hormone (GH ...
