Which prefix is used to denote bone?

Which prefix is used to denote bone?

• A. Aden-
• B. Ost-
• C. Megal-
• D. Proct-

Answer: (B)

Bone-related terms use the combining form oste/o- (often shortened to ost-). This root signals that the word concerns bone, which is why it’s the best fit for terms about the skeletal system or bone conditions. For example, osteoblasts are bone-forming cells and osteoporosis describes a condition involving bone loss. The other prefixes point to different structures: aden- refers to glands, megaly indicates enlargement, and proct- relates to the rectum, so they don’t denote bone.
