肾上腺与肾脏交感神经低级中枢及外周神经元定位研究进展

交感神经是植物性神经系统的重要组成部分。人们采用不同的研究方法,如染质溶解法、HRP法,对交感神经低级中枢位置即交感节前神经元定位和交感神经的外周神经元即交感节后神经元定位进行了广泛和深入的研究。结果表明,交感节前神经元位于胸腰段脊髓中间带区的不同核团内,支配不同器管的交感节前神经元在脊髓内有一定的分布节段;交感节后神经元位于外周植物性神经节内,如交感干神经节、腹腔神经节、肠系膜前神经节、主动脉肾神经节,支配不同器官的交感节后神经元在不同交感干神经节内有一定的分布节段。

Progress on Localization of Sympathetic Preganglionic Neurons and Sympathetic Postganglionic Neurons

Localization of sympathetic preganglionic neurons and sympathetic postganglionic neurons werestudied by using different methods ,such as HRP methods . All the results indicate that the sympatheticpreganglionic neurons were foundin the different neuclei of intermediate zone of the spinal cord .The pre-ganglionic neuronsinnervating different organs were distributedin a certain different spinal segments .Thepostganglionic neurons were observedin the sympathetic trunk ganglia of different segments ,coeliac gan-glion, mesenteric ganglion,aorticorenal ganglion.
