What is the term for the lower jaw bone?

• A. Jaw bone
• B. Mandible
• C. Zygomatic
• D. Temporal

Answer: (B)

The term for the lower jaw bone is the mandible. It is the largest and strongest bone of the face and forms the only movable articulation with the skull at the temporomandibular joints, which lets us chew and speak. The mandible holds the lower teeth and has a horizontal body with two vertical rami ending in the coronoid and condylar processes—the latter fitting into the temporal bone to create that movable joint. The other terms refer to different structures: the generic “jaw bone” isn’t the precise anatomical name, the zygomatic bone is the cheekbone, and the temporal bone is a side-skull bone near the temple.
