The combining form crani/o means which structure?

The combining form crani/o means which structure?

• A. Skull
• B. Crani/o
• C. Spinal cord
• D. Mastoid bone

Answer: (B)

Crani/o is a combining form derived from the Greek word for skull, and it serves as a building block in medical terms. It signals that the topic is the skull, not a specific named structure itself. That’s why the correct idea it conveys is the skull. So when you see crani/o, think skull, and you’ll connect it to terms like cranium, cranial, and craniotomy. The other options correspond to different body parts (myel/o for spinal cord, mastoid/o for the mastoid bone), which aren’t what crani/o means.
