What is the term used for the lower jaw bone?

The lower jaw bone is referred to as the mandible. This bone is the largest and strongest of the facial bones and plays a crucial role in mastication (chewing) as well as supporting the lower teeth. The mandible forms the lower jaw and is anchored to the skull at the temporomandibular joint, which allows for movement necessary for speaking and eating. Its structure is vital for overall facial symmetry and function.

The zygomatic bone, commonly known as the cheekbone, and the maxilla, which forms the upper jaw and holds the upper teeth, do not refer to the lower jaw. The palatine bone is a small bone that helps form the hard palate of the mouth and the floor of the nose but is not related to the jaw's movement or function. Understanding these anatomical distinctions helps clarify the role that each bone plays in the human skull and facial structure.
