Kinocilia-Tuba Uterina

Kinocilia are motile, membrane-enclosed cell processes. They emerge from small bodies ( basal bodies or kinetosomes) under the cell membrane. Cilia are usually 2–5 μm long and have diameters of about 0.2–0.3 μm. That makes them considerably longer than microvilli and easily discernible using light microscopy. Kinocilia are often abundant (cilia border) and form very dense groups at the cell surface. Such cells are called cilia cells.

This figure shows single-layered columnar epithelial cells from the oviduct mucosa, which consists of cilia cells and secretory cells . As seen in light microscopy, the cilia originate with the row of heavily stained basal bodies ( line of basal bodies ). The secretory cells protrude like domes into the lumen of the duct . They interrupt the rows of basal bodies at the inner plasmalemma  .
