Which root means nose?

Which root means nose?

• A. Nas(o)
• B. Neur(o)
• C. Necr(o)
• D. Neo-

Answer: (A)

The concept here is recognizing roots that name body parts. The root for nose is nas/o-, which shows up in terms like nasal or nasogastric, both relating to the nose. The other roots point to different ideas: neur- is about nerves and the nervous system; necr- refers to death or tissue decay; neo- means new. So nas/o- is the correct root because it directly names the nose, while the others refer to entirely different concepts.
