A cilium (plural cilia) is a fine projection from a eukaryotic cell.
Cilium (SILL-ee-um) (plural: cilia) A hairlike projection from a cell surface. The rhythmic beating of cilia can move fluid or mucus over a cell or can propel single-celled organisms. Cilia are shorter than flagella.
cilium pl. cilia
(silly-um) [L. eyelash]
A short cellular appendage specialized for locomotion, formed from a core of nine outer doublet microtubules and two inner single microtubules ensheathed in an extension of plasma membrane.
cilium A short, hair-like flagellum that is found in large numbers and used in movement, for pushing food particles, and in other functions.
in moving particles along the cell surface or, in ciliate protozoans, for locomotion.
Each cilium (and flagellum) grows out from, and remains attached to, a basal body embedded in the cytoplasm. Basal bodies are identical to centrioles and are, in fact, produced by them.
Each cilium or flagellum has a basal body located at its base.
Basal bodies anchor the cilia or flagella and are thought to be responsible for their formation.
basal body A structure at the base of a cilium or flagellum; consists of nine triplet microtubules arranged in a circle with no central microtubule.
base A substance that lowers the hydrogen ion concentration in a solution.
These assemblies are located, however, near the cell surface at the base of each cilium or flagellum, rather than in the centrosome near the nucleus.

Some flagella are not used for movement but in sensation and signal transduction by various cell types, e.g. rod photoreceptor cells of the eye, olfactory receptor neurons of the nose, kinocilium in cochlea of the ear ...
