  2. 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 hypothalamicpituitaryadrenal 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 ...

    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 ...

    They stimulate synthesis of pituitary hormones, stimulate release stored pituitary hormones, stimulate hyperplasia and hypertrophy of target cells and regulate their own receptors. Anterior pituitary produces prolactin, GH, TSH, ACTH, FSH, LH. 15–20% of corticotroph cells, produce ACTH. The targets are the adrenal glands, adipocytes and ...

    The hypothalamicpituitaryadrenal 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 ...

  6. Hypothalamic–pituitary–gonadal axis - Wikipedia

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

    In oviparous organisms (e.g. fish, reptiles, amphibians, birds), the HPG axis is commonly referred to as the hypothalamus-pituitary-gonadal-liver axis (HPGL-axis) in females. Many egg-yolk and chorionic proteins are synthesized heterologously in the liver, which are necessary for ovocyte growth and development.

  7. Endocrine system - Wikipedia

    en.wikipedia.org/wiki/Endocrine_system

    The hypothalamus and the anterior pituitary are two out of the three endocrine glands that are important in cell signaling. They are both part of the HPA axis which is known to play a role in cell signaling in the nervous system. Hypothalamus: The hypothalamus is a key regulator of the autonomic nervous system.

  8. Adrenal insufficiency - Wikipedia

    en.wikipedia.org/wiki/Adrenal_insufficiency

    Adrenal hormone production is controlled by the hypothalamicpituitaryadrenal axis, in which the hypothalamus produces corticotropin-releasing hormone (CRH), which stimulates the pituitary gland to produce adrenocorticotropic hormone (ACTH), which stimulates the adrenal gland to produce cortisol. [12]

  9. Adrenocorticotropic hormone - Wikipedia

    en.wikipedia.org/wiki/Adrenocorticotropic_hormone

    Deficiency of ACTH is an indicator of secondary adrenal insufficiency (suppressed production of ACTH due to an impairment of the pituitary gland or hypothalamus, cf. hypopituitarism) or tertiary adrenal insufficiency (disease of the hypothalamus, with a decrease in the release of corticotropin releasing hormone (CRH)).
