The experiment was conducted on 36 swine fetuses divided into the three developmental groups described by Marrable (1971). In the postdiaphragmatic part, 10 to 20 primary ganglia were found in the sympathetic trunk. They had fused with the secondary structures, and hence the sympathetic trunks studied finally consisted of 6-16 ganglia. It is remarkable that the higher number of primary ganglia did not correspond with the higher number of secondary ones. The variation in the number of secondary ganglia was mainly connected with the interganglionic fusion occurring in the section studied. The standard variation in the length of the sympathetic ganglia increased considerably with the age of the fetuses as well as the analogous coefficient of variation. The analysis of the statistical parameters referring to the ganglia of the investigated section of the sympathetic trunk investigated indicated the growth of its developmental dynamics, which did not occur until the terminal period of gestation.
该实验以36头猪胎儿为对象，这些胎儿被分为Marrable（1971年）所描述的三个发育组。在膈后部分，交感干中发现有10至20个初级神经节。它们已与次级结构融合，因此最终研究的交感干由6 - 16个神经节组成。值得注意的是，初级神经节数量较多并不对应次级神经节数量较多。次级神经节数量的变化主要与所研究切片中神经节间融合有关。交感神经节长度的标准差以及类似的变异系数随胎儿年龄显著增加。对交感干研究切片中神经节相关统计参数的分析表明，其发育动态在妊娠末期才开始增长。
