Which prefix denotes the rib?

Which prefix denotes the rib?

• A. Omo
• B. Myo
• C. Hypo
• D. Costo

Answer: (D)

Costo- designates the rib in anatomical terms. You’ll see it in words like costochondral (rib to cartilage) and costovertebral (rib to vertebra), which clearly ties the root to the rib. The other options point to different ideas: omo- relates to the shoulder region, myo- means muscle, and hypo- means under. Hence costo- is the prefix that denotes the rib.
