The prefix INFRA- means?

The prefix INFRA- means?

• A. In front of
• B. Above
• C. Normal
• D. Beneath

Answer: (D)

INFRA- is a positional prefix used to indicate something located below or beneath another structure. This makes it the opposite of terms that mean above or in front of. When you see infra-, think of being underneath. For example, infraclavicular means below the clavicle; infrapatellar means below the kneecap; infrared refers to light just below the red end of the spectrum. So the meaning that fits INFRA- is beneath. The other options describe in front of (anterior), above (superior), or normal (normo-), which do not match the sense of below.
