Phase-resolved dynamic wavefront imaging of cilia metachronal waves. [PDF]
Quant Imaging Med Surg, 2023 The coordination and the directional order of ciliary metachronal waves are the major factors that determine the effectiveness of mucociliary clearance (MCC). Even though metachronal waves play an essential part in immune response, clinical diagnostic tools and imaging techniques that can reliably and efficiently capture their spatial distribution and ...

THE METACHRONAL WAVE OF LATERAL CILIA OF MYTILUS EDULIS [PDF]
The Journal of Cell Biology, 1972 The form of beat of cilia and the structure of the metachronal wave on the lateral gill epithelium of Mytulus edulis have been studied on living material by interference-contrast microscopy and stroboscopic illumination, and compared with the same features in rapid-fixed preparations studied by light microscopy and with the scanning electron microscope.

Emergence of metachronal waves in active microtubule arrays [PDF]
Physical Review Fluids, 2019 The physical mechanism behind the spontaneous formation of metachronal waves in microtubule arrays in a low Reynolds number fluid has been of interest for the past several years, yet is still not well understood. We present a model implementing the hydrodynamic coupling hypothesis from first principles, and use this model to simulate kinesin-driven ...

Emergence of metachronal waves in cilia arrays. [PDF]
Proc Natl Acad Sci U S A, 2013 Propulsion by cilia is a fascinating and universal mechanism in biological organisms to generate fluid motion on the cellular level. Cilia are hair-like organelles, which are found in many different tissues and many uni- and multicellular organisms. Assembled in large fields, cilia beat neither randomly nor completely synchronously—instead they display

Why antiplectic metachronal cilia waves are optimal to transport bronchial mucus [PDF]
Physical Review E, 2019 The coordinated beating of epithelial cilia in human lungs is a fascinating problem from the hydrodynamics perspective. The phase lag between neighboring cilia is able to generate collective cilia motions, known as metachronal waves. Different kinds of waves can occur, antiplectic or symplectic, depending on the direction of the wave with respect to ...

Bilateral Asymmetry shown by the Metachronal Waves in Protochordate Gill Slits [PDF]
Nature, 1949 MULLER1 stated that metachronal waves travelled round the gill slits of Amphioxus "am vordern Rande aufwarts, am hinten abwarts" ; but he figured them moving in the opposite direction on the left side of the pharynx. Franz2 did not clear up the contradiction, though he, too, noted and figured the metachronal waves.

Metachronal waves in the flagellar beating of Volvox and their hydrodynamic origin. [PDF]
J R Soc Interface, 2015 Groups of eukaryotic cilia and flagella are capable of coordinating their beating over large scales, routinely exhibiting collective dynamics in the form of metachronal waves. The origin of this behaviour—possibly influenced by both mechanical interactions and direct biological regulation—is poorly understood, in large part due to a lack of ...

Hydromechanical properties of metachronal swimming in polychaetes [PDF]
Scientific ReportsFree-swimming polychaetes are common in marine habitats and exhibit a unique form of swimming whereby a metachronal wave occurs simultaneously with a bending body wave.

Synchronous multi-segmental activity between metachronal waves controls locomotion speed in Drosophila larvae [PDF]
eLife, 2022 Abstract The ability to adjust the speed of locomotion is essential for survival. In limbed animals, the frequency of locomotion is modulated primarily by changing the duration of the stance phase. The underlying neural mechanisms of this selective modulation remain an open question.
