| 摘 要： | 为了给涡虫神经生物学的比较研究提供基础资料和通过RNAi技术为研究与脑部再生有关基因的功能奠定基础,本研究使用石蜡连续切片技术,经HE和Masson染色后,对日本三角涡虫Dugesia japonica的神经系统进行观察.日本三角涡虫的中枢神经系统由脑和2条纵神经索组成,脑呈马蹄形;纵神经索从头部到尾部逐渐变细;脑部神经细胞突起连接成网状,纵神经索内神经细胞突起呈纵向排列;咽壁神经组织排列成内外2个圆筒状.这些结构差异反映出日本三角涡虫在涡虫纲系统演化中处于较高级的地位.

| Abstract: | The purpose of this study is to provide crucial insight into the comparative study of the planarians neurobiology and to establish the base for studying the functions of genes which relative to the regeneration of brain with RNAi.The nervous system of planarians(Dugesia japonica) was observed with the light microscope after continuous paraffin section,HE staining and Masson staining.The central nervous system is composed of a horseshoe-shaped brain and two main longitudinal nerve cords that become gradually... |
