Mandible (2023-2024 FICHE DE COURS UE spé 2,3,5): An unpaired, mobile bone of the facial skeleton, connected to the skull at the temporal bone via the temporo-mandibular joint, enabling mouth opening and mastication.
Only mobile bone of the facial skeleton (2023-2024 FICHE DE COURS UE spé 2,3,5): The mandible is unique among facial bones because it is the only bone capable of movement, primarily due to the action of masticatory muscles.
Connected to the skull at the temporal bone via temporo-mandibular joint (2023-2024 FICHE DE COURS UE spé 2,3,5): The mandible articulates with the temporal bone through the temporo-mandibular joint, allowing jaw movements such as opening, closing, and lateral motions.
Mandible consists of two parts: horizontal body and vertical branches (2023-2024 FICHE DE COURS UE spé 2,3,5): The horizontal body forms the main chin area, while the vertical branches extend upward to connect with the skull.
