What are the two bones of the skull?

The skull or cranium is also called the brain case. All the bones of the skull (except the mandible) are firmly interlocked along structures called sutures. Cranium or brain case or helmet is composed of eight bones including the frontal, occipital, sphenoid, and ethmoid bones, along with a pair of parietal and temporal bones. The skull, in an adult, is only one bone made of 8 fused bones. The lower jaw or mandible, is not part of the skull but is part of the face.


What are the 7 skull bones that can move?

I'm not sure, but isn't the skull on big bone? oh well i must be wrong. ---- No, the skull is not one big bone. The skull is made up of 22 bones, excluding the ossicles of the ear (small bones in the middle ear space which serve to transmit sound). There are 6 ossicles in total, three in each ear, and these bones are mobile. The only other skull bone that is able to move is the mandible (jaw bone). Thus, the seven bones that are able to move are: - Mandible - Left Malleus Ossicle - Right Malleus Ossicle - Left Incus Ossicle - Right Incus Ossicle - Left Stapes Ossicle - Right Stapes Ossicle. I hope this helps. Qu.mstr


What bone in the skull is a definitive feature of mammals?

Actually, it's the lack of bones. Mammals' jaws have only the dentary (the lower jaw bone) and the squamosal (the upper jaw bone). Non-mammalian amniotes have two more bones in the skull: the articular in the lower jaw and the quadrate in the upper jaw. In them, the articular and the quadrate fuse to form the joint. In mammals, the articular is the malleus of the middle ear, and the quadrate is the incus.
