Microinjected → It is formed from "micro-" (from Greek "mikros", meaning small) and "inject" (from Latin "iniectus", meaning to throw in). The word "microinjected" refers to the process of injecting something in a very small quantity or into a small area.
Think of 'small' ('micro-') being 'thrown in' ('inject') — that's why microinjected means to inject something in a very small amount.
