Ciliary metachronal wave propagation on the compliant surface of Paramecium cells
Cytoskeleton, 2015Ciliary movements in protozoa exhibit metachronal wave‐like coordination, in which a constant phase difference is maintained between adjacent cilia. It is at present generally thought that metachronal waves require hydrodynamic coupling between adjacent cilia and the extracellular fluid.

Metachronal wave of artificial cilia array actuated by applied magnetic field
Japanese Journal of Applied Physics, 2016Abstract In this paper, a biomimetic microstructure related to cilia, which are effective fluidic and conveying systems in nature, is described. Authors have already reported that a magnetic elastomer pillar actuated by a rotating magnetic field can work like a natural cilium. In the present work, we show examples of a cilia array with a

The Phan–Thien–Tanner non-Newtonian model of fluid flow is considered to mathematically model the cilia governed flow inside the human body. The collective action of cilia generates a rhythmic motion in form of metachronal wave traveling along the wall ...

International Journal of Modern Physics B, 2021
In this paper, the two-phase flow of non-Newtonian fluid is investigated. The main source of the flow is metachronal waves which are caused by the back and forth motion of cilia attached to the opposite walls of the channel. Magnetohydrodynamics (MHD) of

Nature of the mammalian ciliary metachronal wave
Journal of Applied Physiology, 1993The temporal and spatial coordination of ciliary beat (metachronicity) is fundamental to effective mucociliary transport. Metachronal wave period (MWP) and ciliary beat frequency (CBF) of fresh excised sheep and canine tracheal epithelial tissues were measured with the use of a newly developed alternating focal spot laser light scattering system.

Synchronization, phase locking, and metachronal wave formation in ciliary chains [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2008 Synchronization and wave formation in one-dimensional ciliary arrays are studied analytically and numerically. We develop a simple model for ciliary motion that is complex enough to describe well the behavior of beating cilia but simple enough to study collective effects analytically.

AbstractA mathematical model is proposed to explain the dependence of the direction and the length of the metachronal wave on parameters that characterize the ciliary beat, the dimensions of the cilia, and the geometry of their arrangement on the ciliated surface.

Metachronal wave analysis for magnetized Williamson fluid through a ciliated curved channel
Proceedings of the Institution of mechanical engineers. Part E, journal of process mechanical engineeringCilia play an important role in many psychological processes such as locomotion, alimentation, circulation, respiration, and reproduction. Therefore, the present investigation is modeled to study the impact of velocity slip on the cilia motion of ...

Reconstitution of Metachronal Waves in Ciliated Cortical Sheets of Paramecium: I. Wave Stabilities
Journal of Experimental Biology, 1994ABSTRACT We reconstituted metachronal waves on ciliated cortical sheets prepared from detergent-extracted Paramecium multimicronucleatum cells. Ciliary movements of the cortical sheet, whose intracellular side adhered to a glass coverslip, were reactivated by perfusion of a basic reactivation medium containing ATP. In this condition, the
