The distribution of postganglionic neurons innervating the spleen, intestine and kidney in paravertebral and prevertebral sympathetic ganglia was studied in rats using retrograde transport of fluorescent dyes. Labelled cells were counted in the thoracolumbar chain ganglia T6-L4, splanchnic ganglia and the solar plexus (fusion of left and right coeliac ganglia and superior mesenteric ganglion). Most splenic neurons were located in the splanchnic ganglion (64%), mesenteric neurons in the solar plexus (96%) and renal neurons in the sympathetic chain ganglia (80%). These three groups of neurons were distributed in overlapping ganglia within the paravertebral chain. Innervation of the spleen and intestine from the chain ganglia was bilateral, whereas innervation of the kidney was almost entirely ipsilateral. In conclusion, the sympathetic postganglionic neurons controlling the spleen, intestine and kidney have their cell bodies in different ganglia. These three groups of neurons are candidates for innervation by different subgroups of preganglionic neurons.
利用荧光染料逆行运输法，在大鼠身上研究了支配脾脏、肠道和肾脏的节后神经元在椎旁和椎前交感神经节中的分布。在胸腰段链状神经节T6-L4、内脏神经节和太阳神经丛（左右腹腔神经节和肠系膜上神经节融合处）中对标记细胞进行计数。大多数脾神经元位于内脏神经节（64%），肠系膜神经元位于太阳神经丛（96%），肾神经元位于交感链状神经节（80%）。这三组神经元分布在椎旁链内相互重叠的神经节中。来自链状神经节对脾脏和肠道的支配是双侧性的，而对肾脏的支配几乎完全是同侧性的。总之，控制脾脏、肠道和肾脏的交感节后神经元，其细胞体位于不同的神经节中。这三组神经元是不同亚组节前神经元支配的候选对象。
