Hypothalamic–pituitary hormones are hormones that are produced by the hypothalamus and pituitary gland. Although the organs in which they are produced are ...
ATC code H01 Pituitary and hypothalamic hormones and analogues is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products.
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 nuclei are located within these specific regions and zones. [8] It is found in all vertebrate nervous systems. In mammals, magnocellular neurosecretory cells in the paraventricular nucleus and the supraoptic nucleus of the hypothalamus produce neurohypophysial hormones, oxytocin and vasopressin. [9]
Herring bodies or neurosecretory bodies are structures found in the posterior pituitary. They represent the terminal end of the axons from the hypothalamus, and hormones are temporarily stored in these locations. They are neurosecretory terminals. [1]
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 ...
A prolactin modulator is a drug which affects the hypothalamic–pituitary–prolactin axis (HPP axis) by modulating the secretion of the pituitary hormone prolactin from the anterior pituitary gland. Prolactin inhibitors suppress and prolactin releasers induce the secretion of prolactin, respectively. [1] [2]
CRH is a 41-amino-acid peptide hormone that is secreted by the parvocellular neurosecretory cells, which are found within the paraventricular nucleus of the hypothalamus. [9] Stimuli for the release of CRH from the hypothalamus include: Forskolin [10] Interleukin-6 [10] Pituitary adenylate cyclase-activating peptide (PACAP) [10] Stress or trauma
