Sutura Coronaris is a medical term referring to the area where the frontal and parietal bones of the skull meet. The word "sutura" is derived from the Latin verb "suo," which means "to sew." The spelling of "coronalis" is connected to the Latin word "corona" meaning "crown," from which the English word "coronal" is derived. The phonetic transcription of "sutura coronalis" is /su:tu:rə kɔːrɒnəlɪs/. Its precise pronunciation is important in medical discussions to ensure clarity and accuracy of meaning.
Sutura coronalis, also known as the coronal suture, is a term commonly used in anatomy and biology to refer to a specific type of suture found in the human skull. A suture, in this context, is a fibrous joint that exists between two bones, allowing for mobility and flexibility within the skull.
The sutura coronalis specifically refers to the suture found between the frontal bone and the two parietal bones at the top of the skull. This particular suture extends from the bregma - the point where the sagittal and coronal sutures intersect - to the lambda, where the sagittal and lambdoid sutures meet. The sutura coronalis is characterized by its curved, arc-like shape, resembling a crown or wreath, giving it its name.
The primary function of the sutura coronalis is to facilitate the growth and development of the skull during infancy and childhood. It allows for expansion as the brain grows, accommodating the development of the skull bones and maintaining the proper shape and proportions of the head. As an individual ages, the sutura coronalis slowly fuses, becoming ossified and forming a solid connection between the frontal and parietal bones.
The sutura coronalis is of significant importance in several medical disciplines, including neurosurgery, craniofacial surgery, and forensic anthropology. An understanding of the sutura coronalis and its variations can aid in diagnosing skull abnormalities, identifying skeletal remains, and performing surgical procedures on the skull.

The term "Sutura Coronalis" can be broken down into two parts: "Sutura" and "Coronalis".
1. "Sutura" comes from the Latin word "sutura" which means "seam" or "suture". In anatomy, it refers to the fibrous joint between two cranial bones where they are tightly bound together.
2. "Coronalis" is derived from the Latin word "corona" meaning "crown". It refers to the transverse suture or seam which runs across the top of the skull, resembling a crown.
Therefore, the term "Sutura Coronalis" likely originated from Latin and describes the anatomical junction or seam along the top of the skull that resembles a crown.
