Kinocilia-Uterus

Some eukaryotic cells have cilia or flagellae . Kinocilia are cylindrical motile processes, which are 0.2 μm thick and about 2–5 μm long. Their central structure consists of microtubule aggregates that are covered by the cell membrane. Kinocilia occur singly or as bushels (cilia border ). Extremely long kinocilia, such as the tails of spermatozoa, are called flagellae. Cilia and flagellae have a uniformly organize d system of microtubules. Scanning electron microscopy of epithelium reveals a particular clear and impressive image of their surface relief. This f igure shows a ciliate d cell surrounded by cells from the uterine cavum epithelium. The cilia form a tight bushel. They are slender, sometimes arcuate and slightly thicker at their ends. In this preparation, the surfaces of the neighboring epithelial cavum cells can be smooth or show a more or less dense population of microvilli, which may look like buttons or rods.  In contrast to stereocilia , kinocilia are motile cell processes with a complex internal composition and structure.
