Major nerve trunks that supply abdominal viscera contain axons of postganglionic neurons that originate in the coeliac ganglion, superior mesenteric ganglion, inferior mesenteric ganglia, hypogastric nerve ganglia and the sympathetic chain ganglia. Using the retrogradely transported neuronal marker Fast Blue, we mapped the distribution of labelled nerve cells after application of the dye to either the superior coeliac nerves, inferior coeliac nerves, superior mesenteric nerve, colonic nerves or hypogastric nerves. Distinctive patterns of nerve cell locations were associated with each nerve trunk. Within the coeliac ganglion, nerve cells that projected into the superior coeliac nerves were almost exclusively lateral, whilst neurons in the medial part of the coeliac ganglion and in the rostral pole of the superior mesenteric ganglion tended to project into the inferior coeliac nerves. Nerve cells located around the emerging superior mesenteric nerve in the superior mesenteric ganglion contributed the majority of axons to that nerve. Cells in both poles of the inferior mesenteric ganglia contributed the majority of postganglionic axons to the colonic nerves, but some cells in the caudal pole of the superior mesenteric ganglion also projected into the colonic nerves. Postganglionic axons in the hypogastric nerves originated from cells predominantly located in the caudal pole of the inferior mesenteric ganglion; however, cells in the rostral pole of the inferior mesenteric ganglia, the superior mesenteric, coeliac and hypogastric nerve ganglia also contributed some axons. Nerve cells of sympathetic chain ganglia projected into each of the nerve trunks; they were distributed rostro-caudally according to the nerve injected.
支配腹部脏器的主要神经干包含节后神经元的轴突，这些节后神经元起源于腹腔神经节、肠系膜上神经节、肠系膜下神经节、腹下神经节和交感链神经节。使用逆行运输的神经元标记物快蓝，我们在将染料应用于腹腔上神经、腹腔下神经、肠系膜上神经、结肠神经或腹下神经后，绘制了标记神经细胞的分布图。每个神经干都有独特的神经细胞位置模式。在腹腔神经节内，投射到腹腔上神经的神经细胞几乎都在外侧，而腹腔神经节内侧部分和肠系膜上神经节头端的神经元倾向于投射到腹腔下神经。位于肠系膜上神经节中肠系膜上神经起始处周围的神经细胞为该神经贡献了大部分轴突。肠系膜下神经节两极的细胞为结肠神经贡献了大部分节后轴突，但肠系膜上神经节尾端的一些细胞也投射到结肠神经。腹下神经中的节后轴突主要起源于位于肠系膜下神经节尾端的细胞；然而，肠系膜下神经节头端、肠系膜上神经节、腹腔神经节和腹下神经节的细胞也贡献了一些轴突。交感链神经节的神经细胞投射到每个神经干中；它们根据注射的神经在头端到尾端的方向上分布。
