【摘要】 为了揭示双斑蟋Gryllus bimaculatus(1773,DeGeer)腹末神经节内DUM神经元的分布形式,我们应用了中性红染色法和氯化镍逆行染色法.结果表明:DUM神经元主要沿着中线排列成4簇,前三簇的细胞体数量相差不多,只有最后一簇细胞体数量相对较多.这4簇DUM神经元的轴突主要经N3、N5、N7和N8这4条神经侧根传出腹末神经节.更多还原

【Abstract】 In order to probe into distributional of dorsal unpaired median(DUM) neurons of terminal Abdominal Ganglion of Gryllus bimaculatus,We used neutral red staining and cobalt back-filling methods.The result indicates that DUM neurons arrange four bunches along the midline,and the sum of three anterior cell cluster is similar,only the last one is major.Other results are:the axons of four cell cluster com out from nerve lateral roots N3、N5、N7 and N8 mainly.更多还原
