Hydrodynamic flow patterns and synchronization of beating cilia.
We calculate the hydrodynamic flow field generated far from a cilium which is attached to a surface and beats periodically. In the case of two beating cilia, hydrodynamic interactions can lead to synchronization of the cilia, which are nonlinear oscillators. We present a state diagram where synchronized states occur as a function of the distance of cilia and the relative orientation of their be...
متن کاملCilia beating patterns are not hydrodynamically optimal
We examine the hydrodynamic performance of two cilia beating patterns reconstructed from experimental data. In their respective natural systems, the two beating patterns correspond to: (A) pumping-specialized cilia, and (B) swimming-specialized cilia. We compare the performance of these two cilia beating patterns as a function of the metachronal coordination in the context of two model systems:...
متن کاملMotile cilia-specific protein macrocomplexes and cilia beating
In Eukaryotes, except fungi and higher plants, the coordinated beating of the motile cilia propels unicellular organisms and regulate the flow of the extracellular fluids in multicellular life forms. In humans proper beating of these tiny nanomachines ensures removal of the mucus and bacteria out of the airways, circulation of cerebrospinal fluid in brain ventricles, transport of the oocytes in...
متن کاملPatterns of synchronization in the hydrodynamic coupling of active colloids.
A system of active colloidal particles driven by harmonic potentials to oscillate about the vertices of a regular polygon, with hydrodynamic coupling between all particles, is described by a piecewise linear model which exhibits various patterns of synchronization. Analytical solutions are obtained for this class of dynamical systems. Depending only on the number of particles, the synchronizati...
متن کاملCilia-like beating of active microtubule bundles.
The mechanism that drives the regular beating of individual cilia and flagella, as well as dense ciliary fields, remains unclear. We describe a minimal model system, composed of microtubules and molecular motors, which self-assemble into active bundles exhibiting beating patterns reminiscent of those found in eukaryotic cilia and flagella. These observations suggest that hundreds of molecular m...
