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 allows for slight movement, accommodating the growth of the brain. Over time, it typically fuses in adulthood, contributing to the stability of the skull. Proper formation and fusion of the sagittal suture are important for overall cranial health and development.
