This is an electron microscopy picture of a section through the flagellum of a Drosophila melanogaster sperm cell. The base of the flagellum is on the left, and the falgellum's skeleton extends ...

For example, in humans, only a few cell types have motile cilia, namely sperm, epithelia cells in ... completely lacked cilia or flagella. Now it is known that they contain primary cilia, although ...

and the 3D spatio-temporal kinematics of the flagellum can be analyzed. The large imaging volume of the platform revealed the full 3D dynamics of 2133 bovine sperm cells. By providing ...

And yet somehow, the elastic flagella can propel these cells along without provoking a response from their surroundings. The researchers found that sperm tails and algal flagella have an 'odd ...

Human sperm cells and the Chlamydomonas algae both move by wiggling their tails, or flagella. While this motion may seem innocuous, physicists are baffled as to how it works. In theory ...
