  2. Hypothalamic–pituitary hormone - Wikipedia

    en.wikipedia.org/wiki/Hypothalamicpituitary...

    Hypothalamicpituitary hormones are hormones that are produced by the hypothalamus and pituitary gland. Although the organs in which they are produced are relatively small, the effects of these hormones cascade throughout the body.

  3. Neuroendocrinology - Wikipedia

    en.wikipedia.org/wiki/Neuroendocrinology

    The pituitary gland is divided into three lobes: the anterior pituitary, the intermediate pituitary lobe, and the posterior pituitary. 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 ...

  4. Neurohormone - Wikipedia

    en.wikipedia.org/wiki/Neurohormone

    The hypothalamus releasing hormones are neurohypophysial hormones in specialized hypothalamic neurons which extend to the median eminence and posterior pituitary. The adrenal medulla produces adrenomedullary hormones in chromaffin cells , cells which are very similar in structure to post-synaptic sympathetic neurons , even though they are not ...

  5. Hypothalamus - Wikipedia

    en.wikipedia.org/wiki/Hypothalamus

    It synthesizes and secretes certain neurohormones, called releasing hormones or hypothalamic hormones, and these in turn stimulate or inhibit the secretion of hormones from the pituitary gland. The hypothalamus controls body temperature, hunger, important aspects of parenting and maternal attachment behaviours, thirst, [4] fatigue, sleep ...

  6. Hypothalamic–pituitary–adrenal axis - Wikipedia

    en.wikipedia.org/wiki/Hypothalamicpituitary...

    Schematic of the HPA axis (CRH, corticotropin-releasing hormone; ACTH, adrenocorticotropic hormone) Hypothalamus, pituitary gland, and adrenal cortex The hypothalamicpituitary–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 ...

  7. Neuroendocrine cell - Wikipedia

    en.wikipedia.org/wiki/Neuroendocrine_cell

    Here hypothalamic neurosecretory cells release factors to the blood. Some of these factors (releasing hormones), released at the hypothalamic median eminence, control the secretion of pituitary hormones, while others (the hormones oxytocin and vasopressin) are released directly into the blood.

  8. Pituitary gland - Wikipedia

    en.wikipedia.org/wiki/Pituitary_gland

    The pituitary gland or hypophysis is an endocrine gland in vertebrates. In humans, the pituitary gland is located at the base of the brain, protruding off the bottom of the hypothalamus. The human pituitary gland is oval shaped, about 1 cm in diameter, 0.5–1 gram (0.018–0.035 oz) in weight on average, and about the size of a kidney bean. [2 ...

  9. 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).
