In the nasal mucosa capillaries with fenestrated and continuous endothelium have been described. Fenestrated capillaries are distributed all over the tunica propria. They are increasing in number subepithelially and close to the nasal glands. Particularly subepithelially the endothelial fenestrations are facing the epithelium. This interesting, morphological feature has already been described as "polar differentiation" in capillaries of other tissues and has been interpreted as a functional differentiation. The same observations could be made in muscularised veins of the nasal mucosa. Only a few fenestrations could be detected in the endothelium of these vessels, but they were all facing the adjacent epithelium. The results indicate that the morphological peculiarities of the vascular endothelium of the nasal blood vessels are transient specialisations of this particular type of cells due to different physiological needs.
在鼻黏膜中，已描述了具有有孔内皮和连续内皮的毛细血管。有孔毛细血管分布于整个固有层。它们在上皮下和靠近鼻腺处数量增加。特别是在上皮下，内皮窗孔面向上皮。这种有趣的形态学特征在其他组织的毛细血管中已被描述为“极性分化”，并被解释为功能分化。在鼻黏膜的肌化静脉中也可观察到相同的情况。在这些血管的内皮中仅能检测到少数窗孔，但它们都面向相邻的上皮。结果表明，鼻血管血管内皮的形态学特性是这种特定类型细胞由于不同生理需求而产生的短暂特化。
