Dean Vaughn Medical Terminology Practice Test

Cryo- signals cold or freezing temperatures. It comes from Greek kryos, meaning cold or frost, and is used in medical terms to describe exposure to very low temperatures or preservation at those temperatures (for example, cryotherapy or cryopreservation). It does not convey warmth or heat. While frigid also means very cold, cryo- specifically denotes the cold/freezing concept in terminology, which is why Cold is the correct temperature concept here.
