摘  要:中华绒螯蟹神经节存在神经细胞和胶质细胞两类细胞。神经细胞膜为3 层; 细胞质由内质网和核蛋白体的聚合体所构成的尼氏体、高尔基体、线粒体、液泡等细胞器组成; 核膜双层, 核仁明显。胶质细胞内含有似神经细胞的细胞器结构。根据细胞核的形态及核内染色质的分布情况, 可把胶质细胞分成3 类: 星形胶质细胞核最大, 卵圆形; 少突胶质细胞核较小, 圆形; 小胶质细胞核最小, 呈三角形或卵圆形。神经细胞的数量与附肢的生理活动强弱有一定的关系。神经细胞数量多, 附肢活动力强, 反之则弱。Neuron and glial cells of ganglion in the crab Eriocheir sinensis were studied by using optical and transmission electron microscope.Each ganglion consists of many neuron and glial cells.According to the size and shape of cell,nuclei and the distribution of chromatin,the glial cells can be distinguished into three types:astrocyte,oligodendrocyte and microglial cell.The cell membrane appears three layered,and the cytoplasm inclusions of neuron consist of Nissl body,Golgi body,endoplasmic reticulum and mitochondrium.There are many organelles in glial cytoplasm which are similar to those in neuren cell.Astrocyte nucleus is the largest and is ellipse;oligodendrocyte nucleus is spherical;microgolal nucleus is triangle or ellipse and is the smallest one.There is relationship between the quantity of neuron cells and the ability of physiological activity of appendix,that is,the more neuron cells,the stronger the ability of appendix.
