cilia
Microscopic cellular paddles
Cilia are tiny hair-like structures that project from cells.
In the respiratory tract, cilia wave in coordinated motion to sweep mucus and debris toward the throat.
Some single-celled organisms use cilia for locomotion.
The singular is cilium, though it rarely appears outside technical writing.
