One can envisage the approach of resistive force theory by approximating the bent filament as a sequence of straight rods connected at their ends and then computing the drag force density for the individual rods. We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. Both the frequency of the flagellar beat and the wavelength of the flagellar bending waves were reduced, resulting in lower values for the net speed of translational motion see Table 2. User Name Password Sign In. A curved mean shape of the flagellum results in curved sperm swimming paths. An asymptotic solution of the Stokes Flow equations for a self-propelling filament is presented. Self-propulsion at low Reynolds number.

Winding the clock forever. The chirality of ciliary beats. All these findings suggest that the mean curvature of the flagellum depends on active processes within the flagellum. We used parameters in accordance with experimental data see Table 1:
