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).amina propria also contains glands with the ducts opening on to the mucosal epithelium, that secrete mucus and serous secretions. The lamina propria is also rich in immune cells known as lymphocytes. A majority of these cells are IgA-secreting B cells.
The SURFACE EPITHELIUM invaginates into the underlying lamina propria, the endometrial stroma, to form the UTERINE (ENDOMETRIAL) GLANDS. Make note of this stroma. The stromal cells have plump, spindle-shaped nuclei and scanty cytoplasm. This stroma is underneath the the surface epithelium.
