cilia /cil·ia/ (sil´e-ah) sing. cil´ium   [L.]

1. the eyelids or their outer edges.

2. the eyelashes.

3. minute hairlike processes that extend from a cell surface, composed of nine pairs of microtubules around a core of two microtubules. They beat rhythmically to move the cell or to move fluid or mucus over the surface.

Cilia

Tiny, hair-like projections from a cell. In the respiratory tract, cilia beat constantly in order to move mucus and debris up and out of the respiratory tree, in order to protect the lung from infection or irritation by foreign bodies.

Mentioned in: Bronchiectasis, Pneumonia, Sinusitis, Situs Inversus, Whooping Cough

cilia

[L.] plural of cilium.

1. the eyelashes.

2. minute hairlike processes that extend from a cell surface, composed of nine pairs of microtubules around a core of two microtubules. They beat rhythmically to move the cell or to move fluid or mucus over the surface. Of particular importance in the respiratory epithelium, contributing greatly to the mucociliary escalator.

ectopic cilia

arise from the conjunctival surface of the eyelids and cause corneal irritation.

eyelid cilia

the eyelashes; smaller and shorter on the lower lids and may be absent altogether in dogs and pigs. There are also longer tactile hairs on the external surface of the eyelids.
