Cilia (singular: Cilium) are cylindrical organelles[1], built from microtubules, in a “9 + 2” arrangement[2], and dyneins. They are motile structures whereby the beating of cilia creates movement. Cilia are involved in mucociliary clearance in which bacteria, mucus and dust are swept up the respiratory tract into the mouth and eliminated. They are eliminated by swallowing. Furthermore, by the beating of cilia, single cells are able to propel through fluid[3]. The movement of cilia is caused by axoneme. Cilia can also be immotile (primary cilia) and have a “9+0” arrangement where they have 9 peripheral doublet microtubules and 0 single microtubules in the centre[4].
