摘要
对马、驴、牛、羊和猪的荐段交感神经进行的比较解剖认为:荐神经节的数目,马、驴及牛每侧常为5个、羊和猪常为4个,其中牛、羊和猪左右两侧荐神经节的位置基本对称,一般与荐椎的序数相对应。荐神经节通过交通支与相应的脊神经相联系,交通支的数目通常为1～3支。
By dissecting 5 specimens every horses,donkeys,ox,pigs and sheep, the result shows that the number of ganglia sacralis on each side is 5 in the horse, donkey and ox and 4 in the sheep and pig.The position of ganglia sacralis on the right and the left side is basically symmetric in ox,sheep and pig.The position of ganglia sacralis corresponds to that of the same ordinal number vertebrane sacralis. The number of communicative branches is generally 1 to 3.The ganglia sacrals and the corresponding nervi spinals are connected with communicative branches.
