- Skull. The skull is composed of 22 bones that are fused together except for the mandible. These 21 fused bones are separate in children to allow the skull and brain to grow, but fuse to give added strength and protection as an adult.
- Hyoid and Auditory Ossicles. The hyoid is a small, U-shaped bone found just inferior to the mandible. The hyoid is the only bone in the body that does not form a joint with any other bone—it is a floating bone.
- Vertebrae. Twenty-six vertebrae form the vertebral column of the human body. They are named by region: Cervical (neck) - 7 vertebrae. Thoracic (chest) - 12 vertebrae.
- Ribs and Sternum. The sternum, or breastbone, is a thin, knife-shaped bone located along the midline of the anterior side of the thoracic region of the skeleton.

The bones also facilitate body movement by acting In cooperation with numerous muscles attached to the bones by tendons. Bone growth and development continues from birth to about twenty years of age. Cartilage furnishes elastic, supporting connective tissues which protect the bones at the joints from shock and give the skeleton more flexibility.
