  2. 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 ...

  3. Hypothalamic–pituitary–thyroid axis - Wikipedia

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

    The TSH, in turn, stimulates the thyroid to produce thyroid hormone until levels in the blood return to normal. Thyroid hormone exerts negative feedback control over the hypothalamus as well as anterior pituitary, thus controlling the release of both TRH from hypothalamus and TSH from anterior pituitary gland. [2]

  4. 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]

  5. Hypothalamic–pituitary hormone - Wikipedia

    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.

  6. Hypothalamic–pituitary–adrenal axis - Wikipedia

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

    The hypothalamic–pituitary–adrenal axis (HPA axis or HTPA axis) is a complex set of direct influences and feedback interactions among three components: the hypothalamus (a part of the brain located below the thalamus), the pituitary gland (a pea-shaped structure located below the hypothalamus), and the adrenal (also called "suprarenal ...

    If you have low testosterone, it can lead to problems with drive, muscle mass levels, fat distribution, bone density, and even red blood cell production. These signs and symptoms may vary in ...

  8. 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 ...

  9. Neuroendocrinology - Wikipedia

    en.wikipedia.org/wiki/Neuroendocrinology

    The hypothalamus controls the anterior pituitary's hormone secretion by sending releasing factors, called tropic hormones, down the hypothalamo-hypophysial portal system. [3] For example, thyrotropin-releasing hormone released by the hypothalamus in to the portal system stimulates the secretion of thyroid-stimulating hormone by the anterior ...
