The sutura coronal is a fibrous joint located at the top of the skull, connecting the frontal bone to the two parietal bones. This joint plays a crucial role in the structure of the skull, allowing for growth during childhood and providing stability in adulthood. As a type of suture, the sutura coronal is one of several important joints in the human skull, including the sutura sagittalis and sutura lambdoidea. These sutures are essential for protecting the brain and supporting the overall shape of the head.
