- Related terms: Sagittal border
Definition
The term ‘sagittal border of parietal bone’ describes the medial or inner edge of this curved, rectangle-shaped bone. It is the longest and thickest of the parietal bone’s four borders. This edge is dentated and connects with its matching edge on the other side, creating the sagittal suture as the center midline of the skull’s top. The sagittal suture, or the medial or sagittal border of each parietal bone, stretches from the front at a point known as the bregma, all the way to the back, ending at a point called the lambda.
