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 ...
Secretin family: secretin, glucagon, vasoactive intestinal peptide and gastric inhibitory peptide; Somatostatin family; Motilin family; Substance P. Ghrelin is a peptide hormone released from the stomach and liver and is often referred to as the "hunger hormone" since high levels of it are found in individuals that are fasting. Ghrelin ...
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.
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 ...
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 ...
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 ...
Congenital disorders of the stomach include pernicious anaemia, in which a targeted immune response against parietal cells results in an inability to absorb vitamin B12. Other common symptoms that stomach disease might cause include indigestion or dyspepsia, vomiting, and in chronic disease, digestive problems leading to forms of malnutrition.
A prime example of this is pepsin, which is secreted in the stomach by chief cells. Pepsin in its secreted form is inactive . However, once it reaches the gastric lumen it becomes activated into pepsin by the high H+ concentration, becoming an enzyme vital to digestion. The release of the enzymes is regulated by neural, hormonal, or paracrine ...
