Human tooth development the dentogingival junction. This junction has three epithelial types: gingival, sulcular, and junctional epithelium. These three types form from a mass of epithelial cells known as the epithelial cuff between the tooth and the mouth. Much about gingival formation is not fully understood, but it is known that hemidesmosomes form between the gingival epithelium and the tooth and are responsible for the "primary epithelial attachment". Hemidesmosomes provide anchorage between cells through small filament-like structures provided by the remnants of ameloblasts. Once this occurs, junctional epithelium forms from reduced enamel epithelium, one of the products of the enamel organ, and divides
The Outermost House Endicott Peabody declared. It was also revealed during this ceremony that the National Park Service (part of the U.S. Department of the Interior) referred to "The Outermost House" on several occasions in its reports that were filed when making its evaluation of the Outer Cape land for National Park status in the 1950s. Today, there are still "Outermost House" types of structures on the Outer Beach, where occupants live in the same fashion that Beston did in the 1920s. Although Beston's original house was claimed by the elements, the Henry Beston Society of Cape Cod has begun a campaign to
