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 growth and development of the skull during childhood, allowing for the expansion of the brain. 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 and the lambdoid suture. These joints are essential for protecting the brain and providing structural integrity to the skull.
