lamina propria

lamina propria mucosa

A thin layer of loose connective tissue which lies beneath the epithelium and together with the epithelium constitutes the mucosa[WP]. The lamina propria contains capillaries and 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.

Pertanyaan yang Sering Diajukan

What is the lamina propria and where is it found?
The lamina propria is a thin layer of loose connective tissue lying directly beneath the epithelium of mucous membranes throughout the body, including the gastrointestinal tract, respiratory system, and urogenital tract. Together with the overlying epithelium, it forms the mucosa.
What structures are found within the lamina propria?
The lamina propria contains blood capillaries and lymphatic vessels (including central lacteals in intestinal villi that absorb dietary fat), lymphoid aggregates and immune cells (T cells, B cells, plasma cells, macrophages, dendritic cells), and in some regions, glands and smooth muscle fibers.
What is the immunological role of the lamina propria?
The lamina propria is a major site of mucosal immunity. It contains large numbers of immunoglobulin A (IgA)-secreting plasma cells, regulatory T cells, and innate immune cells that maintain tolerance to commensal microbiota while defending against pathogens at mucosal surfaces.
