But virtually all other cells have a primary cilium. Likewise, for many years it was generally assumed that the entire phylum Nematoda, comprising roundworms, completely lacked cilia or flagella.

Structure of a cilium of the green alga Clamydomonas reinhardtii (tomographic segmentation): the cilium is covered by a protein layer (FMG 1). Underneath lies the inner glycocalyx and the ciliary ...

However, its exact structure was previously unknown ... and transmit the force needed for gliding motility from inside the cilium, but instead form a protective layer that regulates the ...

In mature cells, the cilia are disassembled and go away completely. However, the centriole, the structure from which the cilium grows, remains docked on the surface of these mature cells.

Presumably the bundle of fibrils which make up a cilium or flagellum contains both conducting and contractile elements 1. Trypanosome flagella, in common with most flagella and cilia, have 9 ...
