在下丘脑室旁核的小细胞性神经元末梢有加压素(VP),这些神经元又可合成促肾上腺皮质激素释放因子(CRF)。已发现,VP和CRF存在于同一正中隆起外区纤维的神经分泌细胞颗粒中。但是,平行测定垂体门脉中的 VP 和 CRF 显示,VP 的浓度变化与 CRF 的浓度变化不相关,说明它们可能来源于不同部位。Holmes 等最近提出,VP 可能来源于正中隆起的两个区,其中一个区是正中隆起的外区,它可同时释 Vasopressin (VP) is present in the parietal neurons of the hypothalamic paraventricular nucleus, which in turn synthesize corticotropin releasing factor (CRF). It has been found that VP and CRF are present in the neurosecretory cell granules of the same mid-lump outer zone fibers. However, the parallel determination of VP and CRF in the pituitary portal revealed that the change in VP concentration was not correlated with the change in CRF concentration, suggesting that they may originate from different sites. Holmes et al. Recently suggested that VP may be derived from two areas of the uplifted mid-rise, one of which is an uplifted outer area that can be released at the same time
