Lamina propria

Lamina propria is a dense, thick, firm supporting connective tissue containing collagenous fibres. It forms one of the two layers of the the oral mucosa, which is the mucous membrane that covers all oral structures except the clinical crowns of teeth. The oral mucosa is formed by stratified squamous epithelium supported by lamina propria.

The lamina propria may be attatched to the periosteum of the alveolar bone, or it may be interposed over the submucosa, which may vary in different regions of the mouth. For example, the dense lamina propria of the attatched gingiva is connected to the cementum and the periosteum of the bony alveolar process.
