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 ...
In the pyloric region the glands are known as pyloric glands, and in the rest of the stomach they are called gastric glands. [1] Several types of endocrine cells are found in the gastric glands. The pyloric glands contain gastrin-producing cells ; this hormone stimulates acid production from the parietal cells.
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.
Those with autoimmune atrophic gastritis (Type A gastritis) are statistically more likely to develop gastric carcinoma (a form of stomach cancer), Hashimoto's thyroiditis, and achlorhydria. Type A gastritis primarily affects the fundus (body) of the stomach and is more common with pernicious anemia . [ 1 ]
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 ...
Fundic gland polyposis is a medical syndrome where the fundus and the body of the stomach develop many fundic gland polyps. The condition has been described both in patients with familial adenomatous polyposis (FAP) and attenuated variants (AFAP), and in patients in whom it occurs sporadically.
Also known as the stomach flu or bug, norovirus often triggers painful gastrointestinal symptoms as well as fever, aches and headaches within days of exposure. 7 common stomach flu symptoms you ...
Additional cells present include parietal cells that secrete hydrochloric acid and intrinsic factor, chief cells that secrete pepsinogen (this is a precursor to pepsin- the highly acidic environment converts the pepsinogen to pepsin), and neuroendocrine cells that secrete serotonin. [22] [citation needed] Glands differ where the stomach meets ...
