from Wikipedia, the free encyclopedia

As the lamina propria ( lat. "Intrinsic layer") refers to an under epithelia encountered layer of connective tissue . Have a lamina propria

  • Mucous membranes , here referred to as lamina propria mucosae . It represents the carrier layer of the epithelium.
  • Tunica serosa ( peritoneum , pleura ), here referred to as lamina propria serosae .
  • Joint capsule (whose synovial membrane ): here referred to as the synovial lamina propria . It is a loose, cell-rich connective tissue in which fat cells are stored.
  • Eardrum , in the area of ​​the pars tensa there is a lamina propria ; One of these connective tissue fiber layers has a radial course, stratum radiatum, and the other is arranged in a circular manner, stratum circulare .

The lamina propria contains blood vessels , lymph vessels and nerves . In some mucous membranes there are also glands (e.g. oral mucosa , stomach , duodenum ). A layer of smooth muscles , the lamina muscularis mucosae, is embedded in the lamina propria only in the wall of the esophagus and the gastrointestinal tract . The lamina propria of the nasal mucous membrane contains dilated veins (venous sinuses). In addition, plasma cells in the lamina propria of mucous membranes produce immunoglobulin A , which serves the immune defense.
