The sagittal suture is a fibrous joint located on the top of the skull, running from the front to the back. It connects the two parietal bones, which are part of the cranial structure. This suture plays a crucial role in the growth and development of the skull during childhood. As a type of suture, the sagittal suture is one of several that make up the human skull, including the coronal suture and the lambdoid suture. These sutures allow for slight movement between the bones, accommodating brain growth and providing structural integrity to the head.
