Sutura coronalis is a medical term that refers to the seam-like structure found in the skull's anterior section. This structure is also known as the coronal suture or frontal suture. This suture marks the point where the forehead bones meet the parietal bones of the skull. Synonyms for this term include metopic suture, anterior suture, frontoparietal suture, and frontonasal suture. These terms are often used interchangeably, depending on the context in which they are used. While these terms may differ slightly, they all refer to the same anatomical structure. Understanding these synonyms helps medical professionals to accurately communicate with one another.
