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 ...
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 ...
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.
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 ...
- 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.
Other common symptoms that stomach disease might cause include indigestion or dyspepsia, vomiting, and in chronic disease, digestive problems leading to forms of malnutrition. [ 5 ] : 850–853 In addition to routine tests, an endoscopy might be used to examine or take a biopsy from the stomach.
