摘要
采用光镜和透射电镜对成人嗅粘膜进行形态学观察。嗅粘膜以基底膜为界分为上皮层和固有层;固有层内含有大量的Bowmai腺,其胞浆内含有大量分泌颗粒。上皮层有支持细胞、嗅神经原和基底细胞三种成分。前两者胞浆内含有较多的线粒体和内质网。基底细胞接近基底膜,胞浆内细胞器少,在电镜水平成人嗅上皮有三种主要的改变:不典型嗅囊,介于嗅上皮和呼吸上皮之间的上皮结构及邵分呼吸上皮化生。本观察结果对理解嗅觉生理机制和临床疾病对嗅觉功能的影响将有一定帮助。
The morphological observation of abult human mucous membrane has been investigated with the light microscope and T.E.M Olfactory mucous membrane is separated into epithlium and lamina propria by basement membrane The lamina propria contains a lot of Bowman’s glands.There are many;secretory granules in the cytoplasm of Bowman’s gland cells The epithelium consists of sup-porting cells, olfactory neurons and basal cells Supportin cells and olfactory neurons contain plenty of mitochondria and endoplasmic reticula in the cytoplasm The basal cell is attached to the basenent mem-brane, few organelle in the cptoplasm Transmission electron microscope reveals that abult human olfac-tory epithelium has three major changes:atypicl olfactory vesicle respiratory metaplasia and mixing of respirdatory and olfactory epithelial tissues The observations provide the new information necessary to understand the physiological mechanism and clinical disorders that affect olfactory function in humans.
