What are the mandible articular surfaces?

The mandible articular surfaces refer to the areas of the mandible that come into contact with the other components of the temporomandibular joint (TMJ). The mandibular condyle and the articular surface of the temporal bone are the key structures involved in this joint.

Focusing on the correct choice, the mandibular condyle is the rounded end of the mandible that fits into the temporal bone, specifically the mandibular fossa. This contact allows for the hinge and sliding movements necessary for chewing and speaking. The coronoid process, while an important anatomical structure of the mandible, does not participate in the articulation at the TMJ. Instead, it serves as an attachment point for muscles, particularly the temporalis muscle.

Understanding this anatomy is crucial in comprehending how the jaw functions and the mechanics involved in various movements. The correct identification of the articulating surfaces helps in diagnosing and treating TMJ disorders effectively.
