Final answer:
The parietal bones form most of the upper lateral side of the skull, joining at the top and are bordered by the frontal, temporal, and occipital bones, playing a crucial role in protecting the brain and shaping the skull.
Step-by-step explanation:
The parietal bones form most of the top and side walls of the cranium. These bones are paired, with one situated on each side of the skull, and they join together at the top. The parietal bones are bounded by other cranial bones - anteriorly by the frontal bone, inferiorly by the temporal bone, and posteriorly by the occipital bone. The cranial structure, including the parietal bones, serves the essential function of covering and protecting the brain. Additionally, these bones help shape the skull and provide support for surrounding structures.
