irritability
As a technical term in biology, the triggering of responses from small stimuli, such as gentle touch. It is a defining property of living organisms — as through their 'irritability' they do not obey Newtonian mechanics — for they are active and wholly or partly autonomous, in a way that non-living objects (apart perhaps from some machines) are not.
