Published: 4 May 2021
...Junji Yano; Russell Wells; Ying-Wai Lam; Judith L. Van Houten ABSTRACT Calcium ions (Ca 2+ ) entering cilia through the ciliary voltage-gated calcium channels (Ca V ) during the action potential causes reversal of the ciliary power stroke and backward swimming in Paramecium tetraurelia . How...

... with electrical or chemical synapses. It glides along surfaces to find food, propelled by beating cilia on cells at its ventral surface, and pauses during feeding by arresting ciliary beating. We found that when endomorphin-like peptides are applied to an animal, ciliary beating is arrested, mimicking natural...

...Sukanya Lodh; Junji Yano; Megan S. Valentine; Judith L. Van Houten ABSTRACT Paramecium cells swim by beating their cilia, and make turns by transiently reversing their power stroke. Reversal is caused by Ca 2+ entering the cilium through voltage-gated Ca 2+ (Ca V ) channels that are found...

... orientation. Cell profile measurements from microscope images suggest that the characteristic front–rear body asymmetry accounts for the observed orientation rates. Gravikinesis may result from interactions between the propelling cilia and the sedimentary flow around the cell, and it seems unlikely...

...Aleksey Y. Malyshev; Pavel M. Balaban SUMMARY Beating of cilia lining the foregut of gastropods facilitates the swallowing of food and, therefore, plays a role in feeding behavior. Despite the fact that neural control of feeding is well studied in mollusks, no neurons controlling ciliary beating...

...Oliver R. Braubach; Amanda J. G. Dickinson; Carol C. E. Evans; Roger P. Croll SUMMARY Larval molluscs commonly use ciliated vela to swim and feed. In this study we used immunohistochemistry to demonstrate innervation of velar cilia and muscles by monoaminergic and peptidergic fibres...

...-HT. The goal of the present study was to characterize the anatomical and physiological differences between the three known populations of superficial ciliary cells. The pedal and dorsolateral ciliary cells shared common structural characteristics, including flat morphology, dense cilia and lateral...

... the intracellular Ca 2+ level([Ca 2+ ] i ). UV application to the upper ciliary region above the basal body induced ciliary reversal in injected cells. Furthermore,UV application to the tips of cilia induced weak ciliary reversal. Larger areas of photolysis in the cilium gave rise to greater angles of ciliary...

... that these cells contain cilio-excitatory peptides and that Tritonia crawls using ciliary locomotion, the Pd6 neurons may control or modulate cilia used in crawling, turning, or both. Tritonia diomedea Bergh were collected from Dash Point,Washington, USA by SCUBA divers and shipped overnight to Chapel Hill...

.... INTRODUCTION Cilia may be classified into two groups: those in which the ciliary beat pattern remains essentially constant and those in which it is modified. Neural control is common in the latter group and mediates such modifications as reversal of the direc- tion of the power-stroke (Aiello & Guideri, 1964...
