国内外近年工作表明,产生促肾上腺皮质激素释放因子(CRF)的神经元胞体大多数不在内侧基底下丘脑(MBH),而在MBH以外的下丘脑区。但CRF神经元轴突则经过视交叉后区、MBH而到达中隆部和神经叶。电刺激大鼠和狗的下丘脑室旁核(PVH),ACTH释放增加。破坏PVH后,中隆部神经分泌物质减少。许多实验表明,在中隆部释放CRF的轴突末梢可 Recent studies at home and abroad show that the majority of neuronal somatic cells producing corticotropin releasing factor (CRF) are not located in the medial basal hypothalamus (MBH) but in the hypothalamus area other than MBH. However, the axons of the CRF neurons pass through the posterior segment of the optic chiasm and reach the mid-length and nerve lobes of the MBH. Electrical stimulation of hypothalamic paraventricular nucleus (PVH) in rats and dogs increases ACTH release. After the destruction of PVH, Chung Lung neurosecretory substances decreased. Numerous experiments have shown that axon terminals that release CRF in the midlong segment are acceptable
