Anatomical terms of bone

The coronal suture (sutura coronalis) is a dense, fibrous connective tissue joint that separates the frontal bone from the parietal bones of the skull. It runs from the top of the head down the sides in a coronal plane, which is perpendicular to the sagittal suture and the lambdoid suture.

Anatomy

The coronal suture is one of the major sutures of the skull. It is located at the junction where the frontal bone meets the two parietal bones. This suture is important for the growth and development of the skull, allowing for the expansion of the brain during infancy and childhood.

Development

During fetal development, the bones of the skull are not yet fused, allowing for flexibility and growth. The coronal suture, along with other cranial sutures, remains flexible during early childhood to accommodate the rapid growth of the brain. Over time, these sutures gradually ossify and fuse completely in adulthood.

Clinical significance

Premature fusion of the coronal suture, a condition known as craniosynostosis, can lead to abnormal skull shape and potentially increased intracranial pressure. This condition may require surgical intervention to correct the deformity and prevent complications.
