The cilium (from Latin, meaning 'eyelash'; the plural is cilia) is an organelle found on eukaryotic cells and are slender protuberances that project from the much larger cell body.There are two types of cilia: motile and non-motile cilia. The non-motile cilia are called primary cilia which typically serve as sensory organelles. There is a third type of cilium that is only transiently present in the early embryo. These are known as nodal cilia and are crucial in the establishment of the left to right body asymmetry.In eukaryotes, motile cilia and flagella together make up a group of organelles known as undulipodia.
Eukaryotic cilia are structurally identical to eukaryotic flagella, although distinctions are sometimes made according to function or length. Biologists have various ideas about how the various flagella may have evolved.
