The prefix Maxill- denotes which anatomy?

• A. Lower Jawbone
• B. Upper Jawbone
• C. Cheekbone
• D. Tooth

Answer: (B)

Maxill- designates the maxilla, the upper jawbone. The maxilla is the paired bone that forms the upper jaw and contributes to the orbit and the nasal cavity. So terms built with this prefix point to structures in that upper jaw region. For example, maxillary describes something related to the upper jawbone, and maxillofacial refers to the jaw and face area. This contrasts with the lower jawbone, which uses mandibul- for terms like mandibular, and with the cheekbone, which is the zygomatic bone (not covered by maxill-). Teeth-related terms use dent- or odonto-.
