摘　要：摘　要：神经解剖学和生理学的研究证明，迷走神经背核(dorsal motor nucleus of the vagus， DMV)是调控胃机能的重要副交感初级中枢。支配胃的迷走神经纤维主要发自于延髓的DMV。就DMV的细胞构筑和突触联系、DMV对胃的神经支配、电刺激DMV对胃机能的影响以及DMV内的神经递质和受体对胃机能的调控进行综述。

Abstract: Abstract: Neuroanatomical and physiological studies verify that the dorsal motor nucleus of the vagus (DMV) as a parasympathetic preganglionic center plays important roles in regulating gastric function. The vagus nerve dominating the gut originates mostly from the DMV. In this article， the cytoarchitecture and synaptic connection of the DMV， the projection of DMV neurons to the stomach， the effect of electrical stimulation of DMV on gastric function， and the neurotransmitters and receptors within the DMV involved in regulation of gastric function are reviewed.
Key words: dorsal motor nucleus of the vagus; neurotransmitter; gastric motility; gastric acid secretion; vagus nerve
