The document summarizes prenatal and postnatal development of the maxilla. It describes how the palate develops from the primary and secondary palatal shelves between weeks 5-10 of development. The palatal shelves initially grow vertically on either side of the tongue, then reorient horizontally above the tongue where they fuse in the midline. Ossification of the palate begins around week 8 from the maxillae and palatine bones. Postnatally, the maxilla continues growing through processes like sutural growth, surface remodeling, and pneumatization of the maxillary sinuses.
