Frontal drawing of a neonate skull (A) shows the sagittal suture system that divides the cranium and face into 2 halves. This system is made up of the metopic suture, the internasal suture, the intermaxillary suture, and the mandibular symphysis (outlined with a black line).

Lippincott Williams and Wilkins, Philadelphia 2001, Figure 82). B, Frontal drawing of the body of the sphenoid bone, the greater sphenoid wings, and the cartilage between them (black). The sagittal suture system divides to run on either side of the body of the sphenoid bone because it is separated from the greater sphenoid wings by cartilage. C, Frontal drawing of the midfacial structures at approximately 3 years of age. The union of the ethmoid bodies (pink) with the perpendicular plate (orange) as a result of ossification of the cribriform plates (green) makes the ethmoid bone a single bone and stabilizes the interocular and upper nasal regions. The maxilla is beige; vomer, yellow; septal cartilage, light blue.
