FMA:70860 MESH:D007030 Wikipedia:Hypophyseal_portal_system hypothalamohypophyseal portal system hypothalamo hypophyseal system we represent this structure strictly as a system of blood vessels (presumably in line with the FMA). It could also be extended to include neurons and fiber tracts, as per the MESH definition UBERON:0009976 One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland (hypophysis). The hypothalamus is responsible for certain metabolic processes and other activities of the autonomic nervous system. It synthesizes and secretes certain neurohormones, often called hypothalamic-releasing hormones, and these in turn stimulate or inhibit the secretion of pituitary hormones. The hypothalamus controls body temperature, hunger, thirst, fatigue, sleep, and circadian cycles UMLS:C1512570 NCIT:C32759 venae portales hypophysiales portal veins of hypophysis hypothalamo-hypophyseal system hypophyseal portal system venae portales hypophysiales set of portal veins of hypophysis
