Which combining form means bone?

Which combining form means bone?

• A. Scol/o
• B. Tract/o
• C. Oste/o
• D. Arthr/o

Answer: (C)

Bone is expressed by the combining form oste/o (often seen as osteo- in many terms). This form is what you’d attach to suffixes to talk about bone-related concepts, like osteology (study of bones), osteoporosis (loss of bone density), or osteoblast (a bone-forming cell). That linkage is what makes it the right choice here. The other roots point to different body parts or ideas: scol/o means curved (as in scoliosis), tract/o relates to a tract or to drawing/pulling, and arthr/o means joint.
