单词 cilium
释义
cilium

Biology
  • A short minute hairlike structure (up to 10 μ‎m long) present on the surface of many cells, notably in certain protozoans and some types of vertebrate epithelium. Cilia usually occur in large groups and are shorter than eukaryotic flagella, although both organelles have the same structure (see flagellum). Beating of cilia can produce cell movement or create a current in fluid surrounding a cell. See also axoneme.
