The morphology of the choroid plexuses of the lateral, third, and fourth ventricles in dogs was studied by histological and ultrastructural techniques after in situ fixation. Most portions of the plexus in the lateral ventricle showed a parallel arrangement of capillaries, producing a fine corrugation of the overlying layer of epithelial cells. Relatively large amounts of connective tissue separated the capillaries from the epithelium. The fourth ventricle choroid plexus showed short capillary loops projecting into the ventricle and more intimately covered by epithelium. Smaller amounts of connective tissue separated the capillaries from the epithelium. The choroid plexus of the third ventricle showed characteristics seen in the plexuses of both the lateral and fourth ventricles. The total surface of the choroid plexuses in the dog averaged 10.7 cm2, of which 55% was fourth ventricle choroid plexus.
采用原位固定后，运用组织学和超微结构技术对犬侧脑室、第三脑室和第四脑室脉络丛的形态进行了研究。侧脑室脉络丛的大部分区域毛细血管呈平行排列，致使覆盖其上的上皮细胞层形成细微的皱襞。相对大量的结缔组织将毛细血管与上皮细胞分隔开来。第四脑室脉络丛可见短的毛细血管袢突入脑室内，且被上皮细胞更紧密地覆盖。较少的结缔组织将毛细血管与上皮细胞分隔开来。第三脑室脉络丛呈现出侧脑室和第四脑室脉络丛所具有的特征。犬脉络丛的总表面积平均为10.7平方厘米，其中55%为第四脑室脉络丛。
