ciliated columnar epithelium 纤毛柱状上皮 pseudostratified columnar epithelium 假复层柱状上皮 pseudostratified ciliated columnar epithelium 假复层纤毛柱状上皮 Epithelium composed of a single layer of cells, appearing as layered because the column-shaped cells vary in height so the nuclei are at different levels. The basal portions of all the cells are in contact with the basement membrane. It lines the respiratory system and the male reproductive tract. The cilia in the respiratory tract are motile, while the stereocilia in the male reproductive tract are immobile. epithelium pseudostratificatum columnare ciliatum (trachea et bronchi) 上皮伪分层柱状结构（气管和支气管） 由单层细胞组成的上皮，由于柱状细胞的高度不同而呈现为分层，因此细胞核处于不同的水平。所有细胞的基底部分都与基底膜接触。它排列在呼吸系统和男性生殖道中。呼吸道中的纤毛是活动的，而男性生殖道中的静纤毛是固定不动的。
