The dense fibrous periosteum of the developing mandibular and maxillary alveolar bones is continuous with the dense collagenous connective tissue of the gum ridge. The polarized columnar basal cell of the gum ridge epithelium is always intimately associated with the dense connective tissue. Cytoplasmic extensions of these cells are seen to penetrate into the connective tissue. Fine reticular fibers appear to connect the cytoplasmic extensions of the basal cell with the dense collagen bundles of the connective tissue. A similar condition prevails in the hard palate between the basal cell of the epithelium and the periosteum of the palatine bone. The connective tissue of the lip, cheek and soft palate is loosely arranged. The epithelial‐connective tissue junction of the cuboidal cell is smooth. Some fine reticular fibers are seen to connect the layer of the epithelium to the sheath of striated muscle fibers.
