Question

Quizplus · Accepted Answer

The maxillae consist of two bones, a left and a right maxilla, which are fused at the midline to form the upper jaw and palate. This is a basic anatomical fact. The mandible is a single bone, not divided into right and left. The frontal bone is also a single bone in adults, though it develops from two centers of ossification. The "malar bone" or "cheekbone" is another name for the zygomatic bone, not the sphenoid bone.
