Anatomical terminology

A cilium (Latin for eyelash;[1] the plural is cilia) is an organelle found in eukaryotic cells. Cilia are slender protuberances that project from the much larger cell body.[2]

There are two types of cilia: motile cilia and non-motile, or primary cilia, which typically serve as sensory organelles. In eukaryotes, motile cilia and flagella together make up a group of organelles known as undulipodia.[3] Eukaryotic cilia are structurally identical to Eukaryotic flagella, although distinctions are sometimes made according to function and/or length.[4] For information on biologists’ ideas about how the various flagella may have evolved, see evolution of flagella.
