What is the bone that forms the lower jaw called?

The bone that forms the lower jaw is known as the mandible. It is the largest and strongest bone of the human face and plays a crucial role in various functions, including chewing, speaking, and supporting the lower facial structure. The mandible has a U-shaped structure that allows for a range of motions at the temporomandibular joint (TMJ), which connects it to the skull.

The mandible houses the lower teeth and provides attachment points for muscles involved in mastication (chewing). Its unique structure not only allows for movement but also contributes to the overall alignment and function of the oral cavity. Understanding the mandible's anatomy is vital in fields like dentistry, orthodontics, and medicine, as it interacts closely with other craniofacial bones and structures.
