Cilium and flagellum structure,artwork. Cilia and flagella (collectively known as undulipodia) are hair-like protrusions from a cell membrane. They have the same structure,but cilia are generally shorter and more numerous. The core,or axoneme,contains 20 microtubules (white and yellow circles),arranged as a central pair surrounded by nine other pairs,or doublets. Attached to each outer doublet are two dynein arms (blue). Dynein is a motor protein that converts chemical energy into a sliding movement that causes the undulipodium to beat | |
