WORDS THAT USE ADRENO-

What does adreno- mean?

Adreno- is a combining form used like a prefix representing either adrenal or adrenaline, especially used in medical terms.

Adrenal relates to the adrenal glands, a pair of glands located above the kidneys that produce steroidal hormones, including adrenaline (also called epinephrine).

Adreno- is based on the Latin prefix ad-, meaning “toward,” and rēnēs, “kidney.” You can use that to remember where the adrenal glands are found in the body!

Examples of adreno-
