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.

Synchronization, phase locking, and metachronal wave formation in ciliary chains [PDF]

open access: possibleChaos: 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.

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.

Characterization of metachronal wave in beating cilia: Distribution of phases in space

Biorheology, 1989
We have examined phase differences between beating cilia measured in different directions on the surface. The measurements were performed on tissue cultures taken from frog palate epithelium. This experiment was based on a method developed earlier, which measures simultaneously scattered light from two different and relatively small areas.

Influence of metachronal wave on hyperbolic tangent fluid model with inclined magnetic field

International Journal of Geometric Methods in Modern Physics (IJGMMP), 2019
The purpose of this paper is to discuss the theoretical study of a nonlinear problem of cilia induced flow by considering the fluid as anincompressible non-Newtonian fluid (hyperbolic tangent fluid) model by means of ciliated walls. The leading equations

Direct measurement of the velocity of the metachronal wave in beating cilia

Biorheology, 1987
Recently a computerized electro-optical method was developed which enables one to simultaneously measure the frequency and the wavelength of the metachronal waves in beating cilia. The method is based on measurement of scattered light from two areas at a given distance apart.

Structure and function of the metachronal wave in Tubifex tubifex spermatozeugmata (Annelida, Oligochaeta)

Journal of Ultrastructure and Molecular Structure Research, 1988
The spermatozeugmata of Tubifex tubifex are bundles of spermatozoa, stored in the sperma­ thecae and composed of two types of sperm cell s. The eupyrene, fertilizing , spermatozoa are stored parallel to the centrai axial cylinder, whereas the oligopyrene spermatozoa are helically arranged in the cortex. The main portions of their tails are connected by
