WitrynaThe neurohormonal theory explains the major mechanism of heart failure; according to this theory, the level of BNP in the blood increases through activation of the natriuretic peptide system, which acts as a counter-regulatory system, to counteract the impaired neurohormonal balance in response to activation of the … Releasing hormones also known as hypophysiotropic or hypothalamic hormones are synthesized by different kinds of specialized neurons in the hypothalamus. They are then transported along neuronal axons to their axon terminals forming the bulk of the median eminence, where they are stored and released into the hypophyseal portal system. They then rapidly reach the anterior pituitary where they exert their hormonal action. The residual hormones pass into the systemic c…
