What part of the jaw does the mandible form?

The mandible constitutes the lower part of the jaw. It is the only movable bone of the skull and plays a critical role in functions such as chewing and speaking. The mandible consists of a body and two ramus (vertical extensions), which connect to the temporal bone at the temporomandibular joint (TMJ). This anatomical positioning allows for the essential movement required for mastication.

The upper part of the jaw is formed by the maxilla, while the side and front parts incorporate a range of structures that include the maxilla, zygomatic bones, and others within the craniofacial skeleton. Understanding the mandible's role and positioning is fundamental in dental anatomy and procedures, as it can affect tooth alignment, dental occlusion, and overall oral health.
