1.借助电子显微镜研究了来自壁内、交感和背根神经节、延髓和小脑皮质的代表性神经元的薄切片。2.这些神经元的尼氏物质由大量的内质网组成，这些内质网显示出不同程度的取向;在内质网的池、小管和囊泡之上和之间，存在着直径为10至30微米的点状颗粒簇。3.第二个膜系统可以通过较浅和更紧密的池和不存在颗粒而与尼氏体的内质网区分开来。在两种膜系统之间存在着中间形式。尼氏体之间的细胞质含有大量线粒体、圆形脂质内含物和细丝。
1. Thin sections of representative neurons from intramural, sympathetic and dorsal root ganglia, medulla oblongata, and cerebellar cortex were studied with the aid of the electron microscope. 2. The Nissl substance of these neurons consists of masses of endoplasmic reticulum showing various degrees of orientation; upon and between the cisternae, tubules, and vesicles of the reticulum lie clusters of punctate granules, 10 to 30 mµ in diameter. 3. A second system of membranes can be distinguished from the endoplasmic reticulum of the Nissl bodies by shallower and more tightly packed cisternae and by absence of granules. Intermediate forms between the two membranous systems have been found. 4. The cytoplasm between Nissl bodies contains numerous mitochondria, rounded lipid inclusions, and fine filaments.
