What does the prefix 'Cefal' refer to in medical terminology?

In medical terminology, the prefix "cefalo-" or "cephal-" pertains specifically to the head. This prefix is derived from the Greek word "kephalē," which means head. Understanding the significance of this prefix is essential, especially when interpreting medical terms related to the head or cranial area, such as "cephalalgia" (headache) or "cephalometry" (the measurement of the head).

The other options do not relate to the meaning of "cefalo." For instance, terms associated with the body often utilize prefixes like "somato-" or "corpo-," while the heart is typically referenced with prefixes such as "cardio-." Limb-related terminology might use "brachio-" for the arm or "cruro-" for the leg. Recognizing the specific meanings of these prefixes helps in accurately interpreting and understanding various medical concepts.
