Etymology: "Atonicity" is a plain formation: it is built from "atonic" with the suffix "-ity," which turns an adjective into a noun for a state or quality. "Atonic" itself comes from the Greek "atonos," meaning "without tension," formed from the negative prefix "a-" and "tonos," a stretching or tension, the same root that gives English "tone" and "tonic." That root explains the meaning. In the medical sense, muscle tone is the slight, constant tension that keeps muscles ready to act, so an atonic muscle is one that has lost that tension and therefore its strength and control. "Atonicity" names that condition as a whole, so it refers to the state of muscles lacking their normal tension rather than to any single muscle.
