cilium
Microscopic cellular whip
A cilium is a tiny hair-like projection from a cell, typically one of many that beat in coordinated waves to move fluid or propel the cell itself.
Cilia line the respiratory tract, sweeping mucus upward.
In single-celled organisms like paramecia, cilia provide locomotion.
Plural: cilia.
