Show answer and explanation
Correct answer: D. Zygomatic arch
- A. The condyle IS part of the mandible and is the most common site of mandibular fracture in children (subcondylar fracture).
- B. The ramus IS a part of the mandible and can fracture.
- C. The body of the mandible IS a part of the mandible — a common fracture site.
- D. The ZYGOMATIC ARCH is part of the ZYGOMATIC BONE (malar bone), NOT part of the mandible. It is a separate facial bone. Therefore, it cannot be a 'mandibular fracture' — this is the exception.
