用电镜技术研究沙土鼠海马ＣＡ＿１区的神经组织超微结构，发现神经毯内的某些线粒体与突触小泡之间有着密切的形态学关系，在部分线粒休内存在着扁平与无颗粒的线粒体小泡，小泡的横径与线粒体嵴的厚度相近，小泡的长轴与线粒体嵴的长轴排列一致。根据突触小泡的形态、大小、电子密度、分布和排列与线粒体小泡相似的事实。笔者认为这两种小泡是同一性质的细胞器。 Using electron microscopy to study the ultrastructure of hippocampal CA 1 region in gerbils, it was found that some mitochondria and synaptic vesicles in the nerve blanket had a close morphological relationship. In some of the mitochondria, there were flat and non-granular Of the mitochondrial vesicles, the diameter of the vesicles and mitochondrial crest thickness similar to the long axis of the vesicle aligned with the long axis of the mitochondrial crest. According to the fact that the shape, size, electron density, distribution and arrangement of synaptic vesicles are similar to mitochondrial vesicles. I think these two vesicles are the same organelles.
