Anatomical terminology

The coronal suture is a dense, fibrous connective tissue joint that separates the two parietal bones from the frontal bone of the skull.

Structure[edit]

The coronal suture lies between the paired parietal bones and the frontal bone of the skull.[1] It runs from the pterion on each side.

Nerve supply[edit]

The coronal suture is likely supplied by a branch of the trigeminal nerve.[2]

Development[edit]

The coronal suture is derived from the paraxial mesoderm.

Clinical significance[edit]

If certain bones of the skull grow too fast then premature fusion of the sutures may occur.[1] This can result in skull deformities.[1] There are two possible deformities that can be caused by the premature closure of the coronal suture:
