The lamina propria is a layer of interlocking fibers, which gives strength to the epithelium above. It consists mostly of tough collagen fibers, some elastic fibers, and reticulin. In between the fibers are fibroblasts and other connective tissue cells. Beneath the lamina propria of the mucosa is usually a layer called the submucosa. It is a loose connective tissue containing fat, blood vessels, nerves, and lymphatics. In some areas such as the hard palate, the submucosa is also fibrous and binds the overlying mucosa quite firmly. However, there is no submucosa at all beneath the gingival mucosa. The lamina propria of the gingiva is bound directly onto the periosteum. It is therefore often referred to as a mucoperiosteum (▶ Fig. 3.2).
