Root Explanation

Chronaxy is formed from "chronos" (meaning time) and "axia" (meaning worth or value). The term refers to the measurement of the time required for a stimulus to produce a response, thus relating time to its value in physiological contexts.

Memory Tip

Think of 'chronos' as relating to time, and 'axia' as relating to worth — this helps you remember that chronaxy measures the value of time in response to stimuli.
