Metachronal ciliary wave motion analysis on peristaltic flow of hyperbolic tangent nanofluid through an inclined magnetic field in a symmetric channel

International Journal of Modelling and Simulation, 2023
The phenomenon of metachronal wave of artificial cilia activated by the influence of magnetic field has many biological applications. The main aim of the present investigation is to show the effect of magnetic field on peristaltic-ciliary flow of ...

Nature of the mammalian ciliary metachronal wave

Journal of Applied Physiology, 1993
The 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.

Dynamics of a magnetically rotated micro swimmer inspired by paramecium metachronal wave.

Progress in Biophysics and Molecular Biology, 2019
In the past few years, a significant body of research has been devoted to designing magnetic micron scale robotic systems for minimally invasive medicine. The motion of different microorganisms is the nature's solution for efficient propulsion of these swimmers.

Ciliary metachronal wave propagation on the compliant surface of Paramecium cells

Cytoskeleton, 2015
Ciliary 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.

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.

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 engineering
Cilia 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 ...

On metachronism in ciliary systems: A model describing the dependence of the metachronal wave properties on the intrinsic ciliary parameters

Cell Motility, 1990
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 of artificial cilia array actuated by applied magnetic field

Japanese Journal of Applied Physics, 2016
Abstract 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

Reconstitution of Metachronal Waves in Ciliated Cortical Sheets of Paramecium: I. Wave Stabilities

Journal of Experimental Biology, 1994
ABSTRACT 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

Direct measurement of directional disorder for ciliary metachronal wave

2001 Conference Proceedings of the 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
The interrelationship of cilia and the directional disorder of the ciliary metachronal wave were analyzed using digital microscopic images. The degree of synchronization between ciliary beats was determined by the correlation. factor between two different spots. Principal axes of inertia were applied to find out the uniphase directions of beating cilia.
