  2. Hypothalamus - Wikipedia

    en.wikipedia.org/wiki/Hypothalamus

    The hypothalamus is located below the thalamus and is part of the limbic system. [1] It forms the basal part of the diencephalon. All vertebrate brains contain a hypothalamus. [2] In humans, it is about the size of an almond. [3] The hypothalamus has the function of regulating certain metabolic processes and other activities of the autonomic ...

  3. 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 ...

  4. Neuroendocrinology - Wikipedia

    en.wikipedia.org/wiki/Neuroendocrinology

    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. The hypothalamus releases tropic hormones into the hypophyseal portal system to the anterior pituitary (right).

  5. Hypothalamic–pituitary–gonadal axis - Wikipedia

    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]

  6. Hypophyseal portal system - Wikipedia

    en.wikipedia.org/wiki/Hypophyseal_portal_system

    The hypophyseal portal system is a system of blood vessels in the microcirculation at the base of the brain, connecting the hypothalamus with the anterior pituitary.Its main function is to quickly transport and exchange hormones between the hypothalamus arcuate nucleus and anterior pituitary gland.

  7. Releasing and inhibiting hormones - Wikipedia

    en.wikipedia.org/wiki/Releasing_and_inhibiting...

    The principal examples are hypothalamic-pituitary hormones that can be classified from several viewpoints: they are hypothalamic hormones (originating in the hypothalamus), they are hypophysiotropic hormones (affecting the hypophysis, that is, the pituitary gland), and they are tropic hormones (having other endocrine glands as their target).

    Hypothalamic–pituitary hormones are hormones that are produced by the hypothalamus and ... There is a pituitary portal system, with which the hormones are ...

  9. Limbic system - Wikipedia

    en.wikipedia.org/wiki/Limbic_system

    Hypothalamus: a center for the limbic system, connected with the frontal lobes, septal nuclei, and the brain stem reticular formation via the medial forebrain bundle, with the hippocampus via the fornix, and with the thalamus via the mammillothalamic fasciculus; regulates many autonomic processes
