Sign up ×  My understanding is that there are two broad
categories of cilia: motile and non-motile (also called primary.
Examples of the former include sperm flagella and the cilia of
epithelial cells that line the airways.  Examples of the latter
are mostly single cilia that protrude from the cell and act as
an antenna, usually packed with certain receptors (HH pathway,
Notch pathway etc.)  In the inner ear, a primary cilium called
the kinocilium extends out of the center of the apical side of
hair cells and migrates to the lateral side over the course of a
few days. This cilium is non-motile, it is simply anchored to a
basal body which is pulled to one side of the cell.  Does anyone
know of another such example in any other tissue? A single non-
motile primary cilium whose basal body migrates along the apical
plane of the cell after docking with the cell cortex.
