Taxis
(redirected from Galvanotaxis)

   Also found in: Medical, Wikipedia, Hutchinson 0.07 sec.
taxis (tăk`sĭs), movement of animals either toward or away from a stimulus, such as light (phototaxis), heat (thermotaxis), chemicals (chemotaxis), gravity (geotaxis), and touch (thigmotaxis). The turning movements of plants in response to stimuli are called tropisms tropism (trōp`ĭzəm)

Taxis

A mechanism of orientation by means of which an animal moves in a direction related to a source of stimulation. There exists a widely accepted terminology in which the nature of the stimulus is indicated by a prefix such as phototaxis (light), chemotaxis (chemical compounds), geotaxis (gravity), thigmotaxis (contact), rheotaxis (water current), and anemotaxis (air current). The directions toward or away from the stimulus are expressed as positive or negative, respectively. Finally, the sensory and locomotory mechanisms by means of which the orientation is achieved are denoted by a second type of prefix forming a compound noun with taxis. Positive phototropotaxis thus describes a mechanism by means of which an animal carries out a directed movement toward a source of light along a path which permits the animal's paired eyes to receive equal intensities of light throughout the movement.

Studies on galvanotaxis of human neutrophilic leukocytes and methods of its measurement.
Some of these findings are in turn supported by in vitro studies in which isolated epidermal cells, cell clusters, and cell sheets demonstrated galvanotaxis in migrating toward the cathode.
