To get full appreciation of the ultrastructural features in the stria vascularis of human fetal cochlea.
The Stria vascularis in human fetal cochlea were observed by scanning electron microscope.
The cells of the fetal stria vascularis present round. All cell surfaces are covered with a thick layer of microvilli. The transition zone is between the stria vascularis and the spiral prominence. The shape of cells gradually changes on the spiral prominence and becomes more irregular. Several cells have a structure of elongated hexagons. The structure of the intermediate cells, basal cells and capillary were also observed from the fractural surface in the stria vascularis.
The surface structures of the whole stria vascularis were observed by scanning electron microscope, especially the surface appearance of the marginal cells. New information will be provided for understanding the structure and function in the stria vascularis.
全面了解人胎儿耳蜗血管纹的超微结构特征。
采用扫描电子显微镜观察人胎儿耳蜗血管纹。
胎儿血管纹细胞呈圆形。所有细胞表面均覆盖有一层厚厚的微绒毛。血管纹与螺旋隆起之间为过渡区。螺旋隆起上细胞形状逐渐改变，变得更加不规则。部分细胞呈拉长六边形结构。从血管纹的断裂面还观察到中间细胞、基底细胞和毛细血管的结构。
通过扫描电子显微镜观察了整个血管纹的表面结构，尤其是边缘细胞的表面形态。为了解血管纹的结构和功能提供了新的信息。
