Verified step by step guidance

Step 1: Understand the anatomy of the human skull. The human skull is divided into two main parts: the cranium (which houses the brain) and the facial bones (which form the structure of the face). The lower jaw is part of the facial bones.

Step 2: Identify the function of the lower jaw. The lower jaw is responsible for holding the lower teeth and facilitating movements such as chewing and speaking. This bone is unique because it is the only movable bone in the skull.

Step 3: Review the names and locations of the facial bones. The facial bones include the mandible (lower jaw), maxilla (upper jaw), zygomatic bone (cheekbone), and others. The mandible is the largest and strongest facial bone.

Step 4: Compare the options provided in the question. The zygomatic bone forms the cheek, the frontal bone forms the forehead, the maxilla forms the upper jaw, and the mandible forms the lower jaw.

Step 5: Conclude that the mandible is the correct answer because it is the bone that forms the lower jaw in the human skull.
