The lower arch is called the ___.

Explanation:
The lower arch is the mandible, the movable lower jawbone that supports the lower teeth. The upper jaw is the maxilla, a fixed bone, while the zygomatic bone is the cheekbone. The alveolar ridge is the bony crest on each jaw that holds the tooth sockets, not the name of the arch itself.
