The sutura sagital 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 joint plays a crucial role in the growth and development of the skull during childhood. As a type of suture, the sutura sagital allows for slight movement, accommodating the expansion of the brain. Over time, this joint typically fuses in adulthood, becoming a solid connection. Proper development of the sutura sagital is essential for the overall shape and function of the human skull.
