摘　　要：为探讨红腹锦鸡小脑皮层形态结构特征,用光镜和透射电镜观察了红腹锦鸡的小脑皮层显微和亚显微结构.结果表明,红腹锦鸡小脑皮层可分分子层、Purkinje细胞层、颗粒层3层.分子层含少量小细胞,细胞大小在4.5～8.3μm;Purkinje细胞层细胞体呈梨状,底宽在17.8～25.6μm之间,高约为18～30μm,细胞中含有丰富的粗面内质网、游离核糖体、线粒体、高尔基体、溶酶体等;颗粒层的颗粒细胞细胞核大,细胞质少.有髓鞘神经纤维中轴突直径多在0.66～1.62μm之间,轴突或树突中含有线粒体等细胞器,也含有丰富的微管,髓鞘厚约为0.13μm.血-脑屏障的内皮细胞的细胞核呈扁平形,细胞质中多含有线粒体和少量吞饮小泡.To explore morphological characteristics of cerebellar cortex of Chrysolophus pictus, microscopic and submicroscopic of cerebellar cortex of Chrysolophus pictus are observed by light microscope and electron microscope. Result shows that cerebellar cortex of Chrysolophus pictus comprises molecular layer, Purkinje cell layer and granular layer. There are some little cells with diameter 4.5～8. 3μm in molecular layer. Purkinje cell is like a pear in Purkinje cell layer, it＇s base width is 17.8～25. 6μm, it＇s height is 18～30 μm. There are lots of rough endoplasmic reticulum, free ribosome, mitochondria, golgi body, lysosome, etc. in Purkinje cell. Granular cell ratio of nucleus to cytoplasm is high in granular layer. Diameter of axons in myelinated nerve fiber is between 0.66 μm and 1.62 μm. There are some mitochondria and microtubes in the axons. Myelin of myelinated nerve fiber is about 0.13μm thick. Nucleus of endothelial cell in blood-brain barrier is flat. There are always some mitochondria and pinosome in the cytoplasm of endothelial cell.
