What is which bone bears the mandibular fossa?

The bone that bears the mandibular fossa is the temporal bone, which is located on the side of the skull and is part of the cranium. The mandibular fossa is a depression on the temporal bone that articulates with the mandibular condyle of the lower jawbone, also known as the mandible. This joint is called the temporomandibular joint (TMJ) and is responsible for the movement of the jaw, including talking, chewing, and yawning. Dysfunction of the TMJ can lead to pain, difficulty chewing, and other problems.
