Suture Frontal

The frontal suture is a scanty skin plate woven into the cranial vault along the midline. Elongated horizontally, the suture extends from the sagittal suture almost to the vertex. The length of the frontal suture in adults ranges from 5 to 7 cm (average 6 cm), the width is 3.5–5 mm (average 4 mm). In the lateral projection, the frontal suture is formed by two layers of skin - a thin superficial one and a thicker, deeper one. The skin of the suture has two layers: a superficial, thin layer covering the tendons and part of the periosteum along the line of the frontal suture, and a deep, thick layer connecting half of one parietal bone with the cheek of the opposite side. The frontal suture, which is intermediate between the temporal and occipital sutures, allows this arch to connect half of one and half of the other parietal bone. Along the entire length of the anterior edge of the suture, the skin surface layer narrows it downward, giving
