The sutura coronal is a fibrous joint located at the top of the skull, where the frontal bone meets the two parietal bones. This joint runs from ear to ear across the forehead and plays a crucial role in the structure of the skull, allowing for growth during childhood. As a type of suture, the sutura coronal is important for protecting the brain and providing shape to the head. It typically fuses in early adulthood, which helps stabilize the skull. Proper development of the sutura coronal is essential for overall cranial health and alignment.
