The anterior or larger fontanel,also known as the bregma and occasionally as the sinciput, isa diamond-shaped space left at the point of juncture of thefrontal, coronal, and sagittal sutures. It persists as a spacethroughout labor, although somewhat diminished in area bythe approximation of the cranial bones. The posterior or.
