Which word root means 'nerves'?

Which word root means 'nerves'?

• A. cardi
• B. hepat
• C. nephr
• D. neuro

Answer: (D)

Word roots carry the essential meaning. For nerves, the root is neuro- (sometimes neur-). It shows up in terms like neurology, neuron, neural, all tying directly to the nervous system. The other roots point to different organs: cardi- means heart, hepat- means liver, and nephr- means kidney. So neuro- is the best fit because it specifically denotes nerves, not the heart, liver, or kidneys.
