What is mandibular fossa?

The mandibular fossa is a shallow depression located on the underside of the temporal bone of the skull. It is part of the temporomandibular joint (TMJ), which is the joint that connects the jawbone (mandible) to the skull. The mandibular fossa acts as the socket for the condyle of the mandible, allowing for smooth movement of the jaw during activities such as talking, chewing, and yawning.

The mandibular fossa is lined with a dense, smooth cartilage known as the articular disc, which helps cushion the joint and reduce friction during movement. It is also surrounded by ligaments and muscles that help stabilize the joint and allow for controlled movement. Dysfunction of the TMJ, such as temporomandibular joint disorder (TMD), can cause pain, clicking, or difficulty moving the jaw, and may require treatment by a healthcare professional.
