Poikilothermia refers to the limb temperature doing what relative to the environment?

• A. Matching ambient temperature
• B. Raising above ambient
• C. Lowering below ambient
• D. Remains unchanged

Answer: (A)

Poikilothermia means a body part cannot regulate its temperature independently, so its temperature tracks the surrounding environment. The limb will warm up or cool down in step with ambient conditions rather than maintaining its own warmth. That’s why matching ambient temperature is the correct description. If the limb stayed the same as core temperature or stayed notably warmer or cooler than the surroundings, it would imply some level of thermoregulation or abnormal heat retention or loss, which isn’t characteristic of poikilothermia.
