Cranio is a prefix for which structure?

• A. Nerve
• B. Lung
• C. Heart
• D. Skull

Answer: (D)

Cranio- denotes the skull, coming from the Greek kranion. It’s used as a prefix to describe structures or procedures related to the skull, such as cranial bones or cranial nerves (nerves connected with the brain and passing through the skull). Other prefixes name different structures—neur- or neuro- for nerves, pulmon- or pneumono- for lungs, and cardio- for the heart—so cranio specifically points to the skull.
