Where can the ramus be found?

• A. The Maxilla
• B. The Sphenoid Bone
• C. The Temporal Bone
• D. The Mandible

Answer: (D)

The ramus is a part of the mandible—the vertical portion that rises from the angle of the lower jaw. It ends in two key features: the condylar process at the back, which forms the jaw joint with the temporal bone, and the coronoid process at the front for muscle attachment. The inner surface of the ramus also contains the mandibular foramen, through which the inferior alveolar nerve passes. This combination of features is unique to the mandible, so the ramus isn’t found in the maxilla, sphenoid, or temporal bones.
