The combining form laryng/o refers to which structure?

• A. Uterus
• B. Jejunum (second part of small intestine)
• C. Larynx (voice box)
• D. Milk

Answer: (C)

Understanding how combining forms name body parts helps you decode medical terms. The combining form laryng/o points to the larynx, the voice box located in the throat that houses the vocal cords and is essential for sound production. That’s why terms built with laryng/o refer to the larynx, such as laryngitis (inflammation of the larynx) or laryngoscope (instrument to view the larynx). The other options aren’t related to this root: uterus comes from uter/o, the jejunum from jejun/o, and milk from lact/o or galact/o. So, laryng/o corresponds to the larynx—the voice box.
