The prefix Spiro- means which type of coil?

• A. Pulse
• B. Coil
• C. Loop
• D. Spiral

Answer: (B)

Spiro- indicates a coiled or twisted form. It comes from Greek speira meaning coil. In medical terms, it describes objects that are wound or corkscrew-like, such as spirochete bacteria that have a coiled shape. That makes coil the best fit for what spiro- conveys. The other options refer to different ideas (pulse, a generic loop, or a straightforward spiral), which don’t capture the root meaning of spiro- as clearly.
