Computer Simulation of Flagellar Movement:I. Demonstration of Stable Bend Propagation and Bend Initiation by the Sliding Filament Model

摘要: A program has been developed for digital computer simulation of the movement a flagellar model consisting straight segments connected by joints at which bending occurs. The finds values rate each joint solving equations balance active, viscous, and elastic moments joint. These rates are then used to compute next position model. Stable swimming movements, similar real can be generated routinely with 25-segment using 16 time steps/beat cycle. results depend on four assumptions about internal mechanisms: (a) Bending is sliding filament process. (b) active process controlled locally curvature flagellum. (c) Nonlinear resistances stabilize amplitude movement. (d) Internal viscous wavelength explain relatively low sensitivity changes in external viscosity.
