How does cilia move?

Explanation:
Cilia move with a rowing-like, coordinated beat. Many tiny hair-like projections on the cell surface beat together in a rhythmic pattern, producing a directional current across the tissue. Each cilium undergoes a power stroke that pushes fluid one way and a recovery stroke that resets, so the combined effect is a continuous flow of mucus or other substances along the surface. This motion is driven by motor proteins inside the cilium and is distinct from a snake-like, slithering movement or any irrelevant substance.
