Etymology: "Innervations" is the plural of "innervation," a term from physiology for the pattern of nerve supply to a part of the body. The noun is formed from the verb "innervate," which means to supply a body part with nerves or to stimulate it through its nerves, with the suffix "-ion" added to turn the action into a noun. The verb itself is built from "in-" and "nerve," the latter ultimately tracing back to Latin "nervus," meaning sinew or tendon, which was also used for the stringy fibers that carried sensation and movement. The suffix chain is the part of the history that does most of the work. The "-ate" ending that turns "innervate" into a verb came through Latin "-ātus," and the "-ion" ending came through Latin "-iō" (genitive "-iōnis"), which passed through Old French "-ation" into Middle English. English then combined these pieces freely, so "innervation" follows the same pattern as many older English nouns of action.
