Which prefix denotes the adrenal gland?

• A. Splen-
• B. Adreno-
• C. Pharyng-
• D. Ili-

Answer: (B)

The prefix being tested signals the adrenal gland. Adreno- (adren/o) is the combining form used for terms related to the adrenal glands, which sit on top of the kidneys and release hormones like adrenaline and corticosteroids. You’ll see this root in words such as adrenocorticotropic (acting on the adrenal cortex) or adrenaline itself, tying directly to the adrenal glands. The other prefixes point to different organs: splen- to the spleen, pharyng- to the pharynx, and ili- to the ilium/iliac region. So adreno- is the correct indicator for the adrenal gland.
