What is the lower jawbone called, described as the largest and strongest bone of the face?

• A. Mandible
• B. Maxillae
• C. Nasal
• D. Frontal

Answer: (A)

The lower jawbone is called the mandible. It’s the largest and strongest bone of the face because it must withstand the forces of chewing and is the only movable bone of the skull, allowing the mouth to open, close, and articulate with the temporal bones at the temporomandibular joints. The mandible holds the lower teeth and defines the jawline. The other bones mentioned—maxillae form the upper jaw and hold the upper teeth, nasal bones form the bridge of the nose, and the frontal bone makes up the forehead and the upper part of the eye sockets.
