What does the occipital bone form in the skull?

The occipital bone is integral to the structure of the skull as it forms the back portion of the head. This bone is situated at the lower back part of the cranium and plays a crucial role in protecting the brain and providing support for the spinal column. The occipital bone features the foramen magnum, an opening that allows the spinal cord to connect to the brain, highlighting its importance in both structural integrity and neurological function. It contrasts with other bones that comprise different areas of the skull, such as the frontal bone, which forms the forehead, and the parietal bones that contribute to the top and sides of the head.
