There are many important characteristics of the temporal bone.ġ Occipital bone – It makes up part of the base of the skull and is located at the back of the head. Surrounding the eyes are ridges called supraorbital margins that constitute the orbital cavities (eye sockets).Ģ Parietal bones – The skull's sides and roof are made up of these bones.Ģ Temporal bones – you can see that the zygomatic and parietal bones of the head are usually joined by fibrous immovable joints with the occipital, parietal, sphenoid, and sphenoid bones. The skull consists of the following bones:ġ Frontal bone – Also known as the forehead bone, this bone is found at the front of your head. Nerves, blood vessels, and lymph nodes pass through the numerous perforations of the bones (e.g., foramina, fissures). A large number of the bone joints (sutures) in the mature skull are fixed (fibrous). Dura mater, also known as the outer layer of the periosteum, lines the inner surface of the skull bones. Brains rest upon a base and are surrounded and covered by a vault. The skull consists of a cranium and a face, each of which is separate from the spinal column.īones arranged in irregular shapes and patterns make up the skull, which protects the brain from injury. In the human body, the bones that make up these structures collectively make up the axis, the central bony core.
The skull, vertebral column, ribs, and sternum make up the axial skeleton. The skeletal system consists of two groups of bones: the axial and appendicular skeletons.
