The major type of gastric gland is the oxyntic gland that is present in the fundus and the body of the stomach making up about 80 per cent of the stomach area. These glands are often referred to simply as the gastric glands. The oxyntic gland contains the parietal cells that produce hydrochloric acid and intrinsic factor, and chief cells that ...
Mucous gland metaplasia, the reversible replacement of differentiated cells, occurs in the setting of severe damage of the gastric glands, which then waste away (atrophic gastritis) and are progressively replaced by mucous glands. Gastric ulcers may develop; it is unclear if they are the causes or the consequences. Intestinal metaplasia ...
Gastric colonization of this bacterium triggers a robust immune response leading to moderate to severe inflammation, known as gastritis. Signs and symptoms of infection are gastritis, burning abdominal pain, weight loss, loss of appetite, bloating, burping, nausea, bloody vomit, and black tarry stools.
Stomach cancers usually occur due to fluctuations in acidity level and may present with vague symptoms of abdominal fullness, weight loss and pain. The actual cause of stomach cancer is not known but has been linked to infection with Helicobacter pylori , pernicious anemia , Menetriere's disease, and nitrogenous preservatives in food.
- Foveolar hyperplasia (black arrow), as a tortuosity in the "neck" region of the gastric glands. - Scant or minimal inflammatory cells (white arrow), i.e. lack of large numbers of neutrophils and plasma cells.. - Smooth muscle hyperplasia in the lamina propria (in black oval). The diagnosis is by examination of tissue, e.g. a stomach biopsy.
By Jose Sepulveda, Buzz60 Appendicitis is one of those conditions that you wouldn't wish on your worst enemy. The pains are so excruciating you feel like you're going to die, and if left untreated ...
Glands differ where the stomach meets the esophagus and near the pylorus. [23] Near the gastroesophageal junction lie cardiac glands, which primarily secrete mucus. [22] They are fewer in number than the other gastric glands and are more shallowly positioned in the mucosa. There are two kinds - either simple tubular glands with short ducts or ...
The gastric folds consist of two layers: Mucosal layer – This layer releases stomach acid. It is the innermost layer of the stomach. [5] It is affected by the hormone histamine, which signals it to release hydrochloric acid (HCl). Sub-mucosal layer – This layer consists of different vessels and nerves, ganglion neurons, and adipose tissue ...
