Root Explanation

**Epinephrin** → It is formed from "epi-" (meaning upon or above) and "nephros" (meaning kidney in Greek). The word refers to a substance that is produced above the kidneys, specifically by the adrenal glands.

Memory Tip

Think of something that is produced 'above' ('epi-') the 'kidneys' ('nephros') — that's why epinephrin relates to a hormone made by the adrenal glands located above the kidneys.
