Briggs Bridging the Gap (BTG) Medical Interpreter Training Practice Test

The meaning of micro- in medical terms is small. It comes from the Greek mikros and is used to indicate something is tiny in size, amount, or scale. You’ll see it in words like microorganism (a tiny organism), microscopic (visible only under a microscope), and microgram (one millionth of a gram). It does not indicate something large, new, or between, so it wouldn’t be used to convey those ideas. This is why the correct interpretation is that micro- means small.
