本文用冷冻复型与蚀刻方法,在电子显微镜下观察了狗、猫及豚鼠声带的超微形态。声带可分为三层:1.粘膜上皮层:声带最外缘由复层鳞状上皮组成,细胞扁平,一般约7～8层,细胞外缘有微绒毛,胞质少,核膜由两层组成,核脱孔贯通于这两层膜;扁平上皮往内为棘状上皮,细胞间桥粒很多。2.粘膜固有层:电镜下能清晰看见胶原纤维的微丝平行排列,固有 In this paper, the ultrastructure of vocal cords of dogs, cats and guinea pigs were observed under the electron microscope with the methods of freeze-thaw and etching. Vocal cord can be divided into three layers: 1. Mucous epithelium: the outermost vocal cords by the stratified squamous epithelium, flat cells, usually about 7 to 8 layers, the outer edge of microvilli, less cytoplasm, the nuclear membrane from the two layers Composition, nuclear holes through the two films; flat epithelial inward spine-like epithelial cells, many desmosomes. 2. Mucous lamina propria: electron microscopy can clearly see the collagen fibers arranged in parallel microfilaments, inherent
