Lamina Propria Structure Lamina Propria Structure The lamina propria, an essential component of mucous membranes, is characterized by its loose connective tissue composition. Unlike the denser fibrous tissue of the submucosa, the lamina propria exhibits a more compressible and elastic nature. This elasticity is particularly evident in organs necessitating expansion, such as the bladder. The collagen within the lamina propria of such elastic organs is instrumental in their mechanical function ...
