足神经节

足神经节表层神经元胞体无分区分布的现象；

There was no phenomenon of neuronal cell bodies zonation in the pedal ganglia 's surface layer .

其分布的主要特征为：5HT免疫阳性细胞在每对步足神经节都呈对称排列；

The distribution characteristics of the 3 immunoreactive substances are as follows : 5 HT immunoreactive cells in each leg ganglion are symmetrically distributed ;

同时，本工作发现，褶纹冠蚌中枢神经系统脑、足、脏神经节神经元均存在较强的自发荧光：在荧光显微镜下可以观察到神经元发出绿色或红色荧光。

Meanwhile , we found that neurons in the cerebral , pedal and visceral ganglia demonstrate a strong red and green autofluorescence .

三疣梭子蟹胚胎期腹神经链由1对大颚、2对小颚和2对颚足所对应的神经节以及腹部神经链组成。

The ventral nerve cord of the crab in the embryo included 1 pair mandibular neuromere , 2 pairs neuromeres of maxillae , 2 pairs neuromeres of maxillipede and abdomen nerve cord .
