迷走神经背核的研究进展

迷走神经背核（ＤＭＶ）是一个重要的内脏运动核团和内脏感觉核团。ＤＭＶ与中枢及外周存在广泛的纤维联系。ＤＭＶ和孤束核、最后区一起构成了“迷走感觉运动中枢”。ＤＭＶ存在神经－体液回路，使ＤＭＶ神经元可以直接感受外周血及脑脊液中的信息。ＤＭＶ含乙酰胆碱、儿茶酚胺、神经肽类等多种递质及相应受体。ＤＭＶ参与中枢调节胃肠、心血管及内分泌等生理功能。

Progress in the Study of the Dorsal Motor Nucleus of the Vagus Nerve

Dorsal motor nucleus of the vagus nerve(DMV) is an important visceral motor and sensory nucleus which establishes widely connections with the central nervous system and peripheral viscera.The DMV together with the solitary tract nucleus and the area postrema form the so-called vagal sensory and motor center.There is a nerve-CSF circuit on the neurons of the DMV,The CSF-contacting neurons of the DMV could receive chemical message directly from the blood and the CSF,The DMV contains a great variety of neurotransmitters including acetylcholine,catecholamine,neuropeptide,etc.and their receptors.The DMV is involved in the central regulation of gastrointestinal,cardiovascular and endocrine functions.
