longitudinal muscular coat.

Stratified epithelial lining.
Striated muscular fiberscut across.
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).
The lamina propria (more correctly "lamina propria mucosae") is a thin layer of loose connective tissue which lies beneath the
epitheliumand together with the epithelium constitutes the mucosa. As its Latin name indicates it is a characteristic component of the mucosa, "the mucosa's own special layer". Thus the term mucosaor mucous membrane always refers to the combination of the epithelium plus the lamina propria. [H.G. Burkitt et al., eds., "Wheater's Functional Histology, 3rd ed."]
The lamina propria contains
capillariesand a central lacteal(lymph vessel) in the small intestine, as well as lymphoid tissue. Lamina propria also contains glands with the ducts opening on to the mucosal epithelium, that secrete mucus and serous secretions.
