The lamina propria is a constituent of the moist linings known as mucous membranes or mucosa, which line various tubes in the body (such as the respiratory tract, the gastrointestinal tract, and the urogenital tract).s its Latin name indicates it is a characteristic component of the mucosa, the mucosa's own special layer. Thus the term mucosa or mucous membrane always refers to the combination of the epithelium plus the lamina propria. The connective tissue of the lamina propria is very loose allowing it to be very cell rich.
