The following information was taught to me by Coach Harris. The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments, and cartilage that connects them. The skeletal system stores calcium and endocrine regulation, that enable us to survive. They are classified in short bones, long bones, flat bones, and irregular bones. The skeletal system covers the external surface of the epiphyses. The bones contain red and yellow blood marrow.
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. The mandible remains a movable jaw bone and forms the only movable joint in the skull with the temporal bone. The bones of the superior portion of the skull are known as the cranium and protect the brain from damage. The bones of the inferior and anterior portion of the skull are known as facial bones and support the eyes, nose, and mouth.
