一、输卵管的结构输卵管分为间质部、峡部、壶腹部、伞部等四部分,各部既有组织结构的变化,也有独自的功能及内部环境。输卵管壁内层为粘膜,外层为肌肉。粘膜上皮由纤毛细胞和分泌细胞(无纤毛细胞)组成,管腔中并有分泌细胞分泌的液体潴留,为卵子、精子及受精卵提供了维持生命的必要环境。粘膜的功能与形态随月经周期而变化,同时各部的结构也有所不同。纤毛细胞在伞部和壶腹部最多,峡部最少,而分泌细胞则愈接近峡部愈多。另外,排卵期成熟分化型细胞增加,分泌细胞具有发达的微绒毛,分泌功能旺 First, the structure of the fallopian tube Fallopian tube into the interstitial part, isthmus, ampulla, umbrella and other four parts, the existing organizational structure changes, but also has its own function and internal environment. Tubal wall lining for the mucosa, the outer layer of muscle. The mucosal epithelium is composed of ciliated cells and secretory cells (ciliated cells). The fluid in the lumen, secreted by secreted cells, retains the environment necessary for the maintenance of eggs, sperm and fertilized eggs. Mucosal function and morphology with the menstrual cycle and change, while the structure of the ministries are also different. Ciliated cells in the umbrella and ampulla most, isthmus at least, while the more secreting cells are close to the isthmus. In addition, ovulation mature differentiated cells increased secretion of cells with well-developed microvilli, secretion function Wang
