Which bone does the mandible articulate with?

The mandible articulates with the temporal bone at the temporomandibular joint (TMJ). This joint is crucial for the movement of the mandible, allowing actions such as chewing and speaking. The TMJ is unique as it is the only movable joint in the skull, facilitating the essential functions of the jaw.

Understanding the connection between the mandible and the temporal bone is important for comprehending various dental and medical conditions, including TMJ disorders. These disorders can result in pain or dysfunction during jaw movement, highlighting the significance of this articulation in both dental practices and overall health.

The other bones listed do not directly articulate with the mandible in a way that allows for movement or functionality. The maxilla is connected to the mandible through the teeth and gums but does not form a joint. The zygomatic bone and the sphenoid bone are also adjacent to the mandible but do not provide a articulatory connection necessary for jaw movement. Therefore, the articulation with the temporal bone is the defining feature of the mandible's relationship in the skull anatomy.
