What is the combining form for head in medical terminology?

The combining form for "head" in medical terminology is cephal/o. This term is derived from the Greek word "kephalē," which means head. It is commonly used in various medical terms related to the head, such as cephalalgia (headache) and cephalometry (the measurement of the head).

The other terms listed refer to different anatomical structures: cerebr/o pertains to the brain, dent/o refers to teeth, and derm/o relates to the skin. Each of these forms is utilized in specific contexts that do not correspond to the general term for head, which is why cephal/o is the correct choice. Understanding these combining forms is essential for accurately interpreting medical terminology.
