Which two bones join to form the jaw?

The jaw is formed by the combination of the maxillae and the mandible. The mandible, also known as the lower jaw, is the only movable bone of the skull and plays a crucial role in the ability to chew and speak. The maxillae, or upper jaw, is fixed and supports the upper teeth, as well as contributing to the structure of the face and aiding in functions such as speech and feeding.

Together, these two bones create the structure of the jaw, allowing a person to open and close their mouth. The interaction and alignment of the maxillae and mandible are vital for proper dental occlusion, which is the alignment of the teeth when the jaws are closed. Understanding the anatomy of the jaw is essential for those studying esthetics and related fields, as it impacts facial aesthetics and various procedures performed in esthetics.
