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.

Rheological fluid motion in tube by metachronal waves of cilia [PDF]
Applied Mathematics and Mechanics, 2017 This paper presents a theoretical study of a non-linear rheological fluid transport in an axisymmetric tube by cilia. However, an attempt has been made to explain the role of cilia motion on the transport of fluid through the ductus efferentes of the male reproductive tract.

bioRxiv, 2021 Motile cilia are hair-like cell extensions present in multiple organs of the body. How cilia coordinate their regular beat in multiciliated epithelia to move fluids remains insufficiently understood, particularly due to lack of rigorous quantification ...

Metachronal waves in magnetic micro-robotic paddles for artificial cilia [PDF]
Communications Materials, 2021 AbstractBiological cilia generate fluid movement within viscosity-dominated environments using beating motions that break time-reversal symmetry. This creates a metachronal wave, which enhances flow efficiency. Artificially mimicking this behaviour could improve microfluidic point-of-care devices, since viscosity-dominated fluid dynamics impede fluid ...

Metachronal Wave of Cilia Transport in a Curved Channel
Zeitschrift für Naturforschung A, 2015 Abstract In this article, the mechanism of cilia-induced flow is discussed through a mathematical model. In this analysis two-dimensional flow of a viscous fluid is observed in a curved channel with ciliated walls. The features of ciliary structures are determined by the dominance of viscous effects over inertial effects using the long ...

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.

Advanced Engineering Materials, Volume 25, Issue 22, November 2023., 2023 A novel multifunctional magnetically actuated micro‐lamellar mechatronic platform for efficient transportation of droplets and small solid objects is reported. The propulsion is realized using a four‐pole rotating magnet, resulting in two modes of object transportation: “pushing” mode for precise positioning and “bouncing” mode for heavier solid ...

Limnology and Oceanography, Volume 67, Issue 12, Page 2706-2717, December 2022., 2022 Abstract Lobate ctenophores are often numerically dominant members of oceanic epipelagic and midwater ecosystems. Despite this, little is known about their trophic ecology. Multiple, co‐occurring species are often found in these ecosystems and appear to feed similarly via feeding currents that entrain prey.
