| 释义 | cilium noun[ C ] biology specializeduk /ˈsɪl.i.əm/ us /ˈsɪl.i.əm/pluralciliauk /ˈsɪl.i.ə/ us /ˈsɪl.i.ə/ one of the very small parts like hairs on the surface of a cell that move regularly and keep the surrounding liquid moving around it or help an organism with only one cell to move纤毛（细胞表面上伸出的微小毛状突起，其有节律的运动可产生其周围的液体移动，或帮助单细胞生物的移动） STEVE GSCHMEISSNER/SPL/Science Photo Library/GettyImages Cells actin anaphase anti-platelet assort axoplasm histochemistry histography homologous chromosomes infiltration intercellular neoplasia nerve fibre neurofibril neurofibrillary neuroglia teratoma tetrad thrombocyte thymocyte turgor The body is covered with uniform cilia except at the anterior extremity. The cilia move very rapidly when quite fresh, and are therefore not easily seen. The cilia which propel them secure the aeration of the system. The entire body is covered with uniform and delicate cilia, which are placed in longitudinal rows. They are little oval bodies with two cilia, which may sometimes be rendered visible by staining with iodine. Examples of ciliumcilium For some of these papillae a cilium could be seen extended from the central stoma. The action of cilia moves the mucus along with the bacteria out of the lung. Apart from evidence that the primary cilium can detect flow, its function is still largely unknown. In some types of cultured mammalian cells one of the centrioles, the maternal centriole, often develops a rudimentary cilium during interphase. The bean-shaped nucleus of each flame cell was situated laterally to the cilia tuft (fig. 4). At present, the renal primary cilium and its role in cyst formation provide the paradigm for understanding its structure and function. Monoclonal antibodies specific for an acetylated form of a-tubulin recognise the antigen in cilia and flagella from a variety of organisms. A novel myosin-like protein (myocilin) expressed in the connecting cilium of the photoreceptor : molecular cloning, tissue expression and chromosomal mapping. As metacercariae mature, these papillae become shorter with a thickening of the tegument but still retaining an opening to the cilium within. Occasionally, a cilium could be seen extended from the central stoma. The mature embryo is a true hexacanth but does not possess swimming appendages like cilia. An approach to digital image analysis of bending shapes of eukaryotic flagella and cilia. The primary cilium might also be involved in chemosensation. Patients have reduced or absent cilia motility, and a wide range of abnormalities in the ultrastructure of the cilia are associated with this phenotype. The cilia are used to latch the trap shut.
