Think of the skull base as a central hub, and the sphenoid bone sits right in the middle of it. It forms joints with almost all the other cranial bones—frontal at the top, the parietals and temporals on the sides, the ethmoid in front, and the occipital at the back—helping to create the floor of the cranial cavity. This central bridging role is why the sphenoid is described as articulating with multiple bones and is often called the keystone of the skull. While the occipital bone also contributes to the base and does meet other bones, it doesn’t connect with as many cranial bones as the sphenoid. The frontal bone and the maxilla are more involved in the face and the upper facial structure rather than forming the skull base. So, the bone forming the base of the skull and articulating with others is the sphenoid.
