Which bony prominence is located at the lower jaw?

• A. The maxilla
• B. The zygomatic bone
• C. The mandible
• D. The nasal bone

Answer: (C)

The mandible, commonly known as the lower jaw, is the only movable bone of the skull and plays a crucial role in the structure of the face. It supports the lower teeth and forms the chin, making it distinct from the other bones listed. The mandible connects with the temporal bone at the temporomandibular joint, which allows for the movement necessary for chewing and speaking. In comparison, the maxilla is the upper jawbone that contains the upper teeth, while the zygomatic bone forms the prominence of the cheeks and does not contribute to the jaw structure. The nasal bone, on the other hand, is part of the framework of the nose, which is far removed from the jaw area. Therefore, the mandible stands out as the bony prominence specifically located at the lower jaw.
