The skull is made up of many bones having their own name.  For instance, the orange bone is known as the Temporal bone and the light blue bone is known as the mandible.  The joint which allows you to open and close your mouth takes on the names of the bones which join at the joint.  That joint is known as the Temporo-Mandibular Joint also known as the TMJ.
