The correct answer is "occipital, occipital bone". The occipital bone is a cranial bone located at the back of the skull. It forms the base of the skull and protects the brainstem and cerebellum. It is connected to the parietal and temporal bones, as well as the sphenoid bone. The occipital bone has several important features, including the foramen magnum, which allows the spinal cord to connect with the brain, and the occipital condyles, which articulate with the first cervical vertebrae.
