What is the name of the lower jawbone?

• A. Maxillae.
• B. Mastoid.
• C. Mandible.
• D. Zygoma.

Answer: (C)

The lower jawbone is called the mandible. It is the largest and strongest bone in the human face and is pivotal for various functions such as chewing and speaking. The mandible is the only movable bone of the skull, which allows for the opening and closing of the mouth. This mobility is crucial for the mechanics of mastication (chewing) and plays a significant role in the articulation of speech. In contrast, the maxillae refers to the two upper jawbones that form the upper jaw and hold the upper teeth. The mastoid is a bony prominence behind the ear, and the zygoma, also known as the cheekbone, contributes to the structure of the face but is not involved in the jaw's movement or function. Each of these bones has distinct functions and locations within the skull, separating them from the role of the mandible.
