A key to understanding the endocrine relationship between hypothalamus and anterior pituitary is to appreciate the vascular connections between these organs. As will be emphasized in later sections, secretion of hormones from the anterior pituitary is under strict control by hypothalamic hormones. These hypothalamic hormones reach the anterior pituitary through the following route: * A branch of the hypophyseal artery ramifies into a capillary bed in the lower hypothalamus, and hypothalmic hormones destined for the anterior pituitary are secreted into that capillary blood. * Blood from those capillaries drains into hypothalamic-hypophyseal portal veins. Portal veins are defined as veins between two capillary beds; the hypothalamic-hypophyseal portal veins branch again into another series of capillaries within the anterior pituitary. * Capillaries within the anterior pituitary, which carry hormones secreted by that gland, coalesce into veins that drain into the systemic venous blood. Those veins also collect capillary blood from the posterior pituitary gland., Anatomia cerca seno cavernoso, Anatomia caracteristicas dimensiones 15x10x6, Embriologia unidad hipotalamo-pituitaria 20 semanas, Celulas cambios tirotropas hipertrofia deficit t4 t3 aumenta tam hipofisis corticotropas degranulación degeneración de COOKE hialina estado de hipercortisolismo gonadotropas hipertrofia klinefelter turner menopausia, Hormonas distribucion arterial venosa relacion anatomofisiologica, Embriologia remanentes bolsa de rathke, Embriologia anterior detectable a las 4-5 semanas, Somatotropas son 50%, dimensiones 15x10x6 peso 0.5-0.9 gr, Embriologia posterior nucleo ventromedial hipotalamo evaginacion del tercer ventriculo, Celulas otras HCG tambien pero incierto origen, mecanismo inhibicion / estimulacion otros estres inanicion ejercicion sueño, claves repaso adenohipofisis neurohipofisis acidofilas basofilas cromofobas cuerpos de Herring glandula pineal organos circumventriculares, Celulas diferenciacion prop1 pit1, HORMONA crecimiento funciones acciones, HORMONA crecimiento estimula mecanismo inhibicion / estimulacion, Anatomia ver silla turca
