  2. Submucosa - Wikipedia

    en.wikipedia.org/wiki/Submucosa

    The submucosa (or tela submucosa) is a thin layer of tissue in various organs of the gastrointestinal, respiratory, and genitourinary tracts. It is the layer of dense irregular connective tissue that supports the mucosa (mucous membrane) and joins it to the muscular layer, the bulk of overlying smooth muscle (fibers running circularly within layer of longitudinal muscle).

  3. Neonatal-onset multisystem inflammatory disease - Wikipedia

    en.wikipedia.org/wiki/Neonatal-onset_multisystem...

    The diagnosis is based on observing the patient and finding the constellation of symptoms and signs described above. A few blood tests help, by showing signs of long-standing inflammation. There is no specific test for the disease, though now that the gene that causes the disease is known, that may change. [citation needed]

    The first symptoms often include acute abdominal pain with diarrhoea or vomiting. [7] Muscle pain and general tiredness are frequent, [7] and low blood pressure is also common. [15] Symptoms can also include pink eye, rashes, enlarged lymph nodes, swollen hands and feet, and "strawberry tongue". [6] Various mental disturbances are possible. [6]

  5. Submucosal glands - Wikipedia

    en.wikipedia.org/wiki/Submucosal_glands

    The submucosa is the tissue that connects the mucosa to the muscle outside the tube. The glands themselves are quite complex. The mucus factory is at the bottom, in the submucosa, it is composed of many little sacs (acini) where the mucus originates. Each sac (acinus) has one end that can open and close (dilate) to allow the mucus out.

    The submucosa consists of a dense and irregular layer of connective tissue with blood vessels, lymphatics, and nerves branching into the mucosa and muscular layer. It contains the submucous plexus, and enteric nervous plexus, situated on the inner surface of the muscular layer.

  7. Duodenum - Wikipedia

    en.wikipedia.org/wiki/Duodenum

    Like other structures of the gastrointestinal tract, the duodenum has a mucosa, submucosa, muscularis externa, and adventitia. Glands line the duodenum, known as Brunner's glands, which secrete mucus and bicarbonate in order to neutralise stomach acids. These are distinct glands not found in the ileum or jejunum, the other parts of the small ...

  8. Brunner's glands - Wikipedia

    en.wikipedia.org/wiki/Brunner's_glands

    Duodenal glands are situated within the mucosa and submucosa of the duodenum. They are most abundant near the pylorus, growing shorter and more sparse distally towards the terminal portion of the duodenum. [1] The duodenum can be distinguished from the jejunum and ileum by the presence of Brunner's glands in the submucosa. [citation needed]

  9. Infantile cortical hyperostosis - Wikipedia

    en.wikipedia.org/wiki/Infantile_cortical...

    In the early stages of infantile cortical hyperostosis, biopsy shows inflammation of the periosteum and adjacent soft tissues. After this resolves, the periosteum remains thickened, and subperiosteal immature lamellar bone can be seen on biopsy, while the bone marrow spaces contain vascular fibrous tissue.
