A type of amenorrhea induced by excessive exercise is named for this structure.
This structure contains the only cells that produce orexin. A group of cells in this organ fail to migrate in Kallman's syndrome. A type of amenorrhea induced by excessive exercise is named for this structure. CART, Agouti-Related Peptide, and NPY are synthesized by a group of cells in this structure which are activated by ghrelin, are inhibited by leptin, and localize to the (*) arcuate nucleus. The magnocellular cells in this organ's paraventricular nucleus synthesize oxytocin and vasopressin, while other signaling factors synthesized here are secreted into the hypophysial portal system in order to trigger the release of hormones from the pituitary. For 10 points, name this master neuroendocrine regulatory organ found near the bottom of the brain.
