Which term demonstrates the use of the IPSI- prefix to indicate the same side of the body?

• A. Ipsilateral
• B. Contralateral
• C. Bilateral
• D. Unilateral

Answer: (A)

The idea being tested is how the prefix in anatomy terms conveys location relative to the body. “Ipsilateral” uses the prefix “ipsi-” meaning on the same side, combined with “lateral” for side. So ipsilateral literally describes structures or symptoms located on the same side of the body as a reference point. That’s why it’s the best choice: it directly communicates “on the same side.” For example, the right kidney and right ureter are ipsilateral. In contrast, contralateral means opposite side; bilateral means on both sides; unilateral means on one side only.
