用扫描电镜较全面地观察了人胎儿脑室系统──侧脑室、第三脑室和第四脑室壁的超微结构。结果发现人和某些动物一样，几个脑室室管膜表面都覆盖着大量的纤毛和微绒毛。纤毛的分布在区域上有一定的差别。并证实了３个脑室内存在着接触脑脊液神经元的胞体、树突和轴突。该神经元的胞体为梭形或球形，可见到一个或两个以上的突起。室管膜上神经纤维发自神经细胞或自室腔外穿入而来。另外，在室管膜上还观察到了神经胶质样细胞和类组织细胞。神经胶质样细胞呈不规则球形，表面比较光滑，有较多的丝状或棘状突起自胞体伸出，没有轴突和树突之分。类组织细胞，大多呈球形，表面有微绒毛或泡状结构，突起较少。在某些区域还可见其聚集成群。本文并对上述各种结构的功能进行了讨论。
Scanning electron microscopy more comprehensive observation of human fetal ventricular system ─ ─ lateral ventricle, third ventricle and the fourth ventricle ultrastructure. The results showed that, like some animals, several ventricular ependymal surfaces are covered with a large amount of cilia and microvilli. Cilia distribution in the area there are some differences. And confirmed the presence of cell bodies, dendrites, and axons in 3 of the ventricles that contact cerebrospinal fluid neurons. The cell body of the neuron is fusiform or spherical, and one or two or more protrusions can be seen. Ependymal nerve fibers from nerve cells or from the perforation of the chamber came. In addition, glial-like cells and histiocytes were also observed on the ependymal membrane. Glial-like cells were irregular spherical, the surface is relatively smooth, there are more filamentous or spine-like protrusions protruding from the body, no axons and dendritic points. Tissue cells, mostly spherical, microvilli or bubble surface structure, less protrusions. In some areas can also be seen gathered in groups. This article also discussed the various functions of the above structure.
