No, It is not the only one.

My lecturer said only joints are movable not bones and yes the bones of the skull are immovable unless you say facial bones. The joints of the skull are only movable when one is a baby, that is just according to my understanding
Mostly we consider the mandible as the only bone in the head that moves, however, technically more than that actually move. The controversy about whether the bones of the skull move relative to each other has absorbed more hours of discussion in the lives of Cranial Therapists than perhaps any other subject. The human skull is generally considered to consist of twenty-two bones—eight cranial bones and fourteen facial skeleton bones. The auditory ossicles (malleus, incus, and stapes) of each ear are also bones in the head separate from the skull. In the neurocranium there are the occipital bone, two temporal bones, two parietal bones, the sphenoid, ethmoid and frontal bones. One of the components of the cranial concept for practitioners who practice cranial osteopathy or craniosacral therapy is that the BONES OF THE HEAD MOVE ALONG THE SUTURES. The movement can be described as an expansion and compression that take place much how the rib cage moves during respiration. So perhaps we could say all of them move?
