Kinesis

Origin

From Ancient Greek κίνησις (kinēsis, "motion, movement").

Noun

1. the movement of an organism in response to an external stimulus

Usage notes

Unlike taxis, the movement can be in any direction or even random. Its rate — that is, the frequency of turning or reorientation, or of activity — depends on the intensity of the stimulation.
