The coronal suture is a fibrous joint located in the human skull. It runs horizontally across the top of the head, connecting the frontal bone to the two parietal bones. This suture plays a crucial role in the structure of the skull, allowing for growth during childhood and providing stability as the bones fuse together in adulthood. As a type of suture, the coronal suture is one of several that make up the cranial structure. Other important sutures include the sagittal suture, which runs along the midline of the skull, and the lambdoid suture, located at the back. These sutures help protect the brain and support the overall shape of the head.
