Membrane-enclosed motile structure extending from the surface of eukaryotic cells. Cilia usually occur in groups and beat rhythmically to move a cell (e.g., single-celled organism) or to move small particles or fluid along the surface (e.g., trachea cells). See also axoneme and flagellum.
Hairlike extension of a cell containing a core bundle of microtubules and capable of performing repeated beating movements. Cilia are found in large numbers on the surface of many eucaryotic cells, and they are responsible for the swimming of many single-celled organisms.
Latin = eyelid, hence, an eyelash; adjective - ciliary, or ciliated.
(Latin, = eyelid, from the hairlike appearance of a cilium; plural, cilia)
A slender organelle that extends above the free surface of an epithelial cell and generally undergoes cycles of movement; composed of a basal body and microtubules in a 9 + 2 array.
(pl. cilia) eyelash; hairlike vibrating organ on animal or vegetable tissue.
a hairlike projection from the surface of a cell; provides locomotion in free-swimming unicellular organisms
any of the short curved hairs that grow from the edges of the eyelids
Small hair-like projections that line the airway, middle ear, and paranasal sinuses that move rhythmically to clear particulates and bacteria from the lung.
(plural, cilia) A short cellular appendage specialized for locomotion.
(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.
(pl. Cilia): one of the marginal hairs bordering the auricle.
A hairlike structure on some cells. It beats rapidly to move the cell or produce feeding currents. (plural: cilia)
A short hair like structure on the surface of many cells. Cilia are typically much shorter than the length of the cells they are part of, and have a return and a power stroke involving the whole length of the structure. The plural of cilium is cilia.
A cilium (plural cilia) is an organelle found in eukaryotic cells. Cilia are thin, tail-like projections extending approximately 5–10 micrometers outwards from the cell body. There are two types of cilia: motile cilia, which constantly beat in one direction, and non-motile cilia, which typically serve as sensory organelles.
