The occipital bone also forms the atlanto-occipital joint with the atlas (the first cervical vertebra in our spine). The occipital bone (/ k s p t l /) is a cranial dermal bone and the main bone of the occiput (back and lower part of the skull).It is trapezoidal in shape and curved on itself like a shallow dish. Our occipital bone contains the foramen magnum, the hole through which the spinal cord enters the skull to attach to the brain. In this region we have eight cranial bones:Ĭollectively, these bones provide a solid bony wall around the brain, with only a few openings for nerves and blood vessels. Surrounding the brain is a region of the skull known as the cranium. Upon reaching maturity, our skull bones fuse to produce a rigid protective shell for the soft nervous tissue of our brain. Early separation of the bones provides the fetal skull with the flexibility necessary to pass through the tight confines of the birth canal.ĭuring childhood development, the skull bones remain somewhat separated, allowing for growth of the brain and skull. The only bone that remains separate from the rest of the skull is the mandible, or jaw bone. As these bones grow throughout fetal and childhood development, they begin to fuse together, forming a single skull. Depending on where they develop, osteomas can sometimes cause symptoms such as headaches or sinus infections. During fetal development, the bones of the skull form within tough, fibrous membranes in a fetus’ head. An osteoma is a benign bone tumor that typically forms on the skull.
