A mucus is a slippery fluid that is naturally produced by the mucous membranes in your body. It is found in the nose, throat, lungs, and intestines. Mucus
MUCOUS MEMBRANE OF STOMACH The reddish-gray mucous membrane of the stomach, composed of a surface layer of epithelial cells, the lamina propria, and the muscularis mucosae, commences at the cardia along an irregular or zigzag line (referred to as the Z line). Deep to the mucosa is the submucosa and three external muscle layers of the stomach. When the stomach is empty, the mucosa appears to be formed of folds (rugae), which flatten considerably when the stomach is distended. In the region of the lesser curvature, where the mucosa is more strongly fixed to the underlying muscular layer, the folds take a longitudinal course. The rugae are generally smaller in the fundus and become larger as they approach the pyloric portion of the stomach, where they show a tendency to run diagonally across the stomach toward the greater curvature. Besides these broad folds, the gastric mucosa is further characterized by numerous shallow invaginations, which divide the mucosal surface into a mosaic of elevated areas varying in shape. When viewed under magnification, several delicate ledges, or mammillated areas, and depressions, known as gastric pits, can be seen. Gastric glands empty into the stomach lumen through the gastric pits. The gastric epithelium consists of a single layer of simple columnar cells, and it is sharply demarcated from the stratified squamous epithelium of the esophagus at the gastroesophageal junction in the cardiac area of the stomach. The columnar epithelial cells are of the mucoid type and contain mucigen granules in their outer portions and a single ovoid nucleus at their base. These cells line the tubular cardiac glands along with mucoid neck, chief, parietal, and enteroendocrine cells that allow the stomach to carry out its functions. 1. The cardiac glands are confined to a narrow zone, 0.5 to 4 cm in width, around the cardiac orifice. They are coiled and are lined almost entirely by mucus-producing epithelial cells. 2. The gastric, or fundic, glands are located in the fundus and over the greater part of the body of the stomach. They are fairly straight, simply branched tubules, with a narrow lumen reaching down almost to the muscularis mucosae. They are lined by four types of cells: (1) The mucoid neck cells are the same as seen in the cardiac region but differ from the cells of the surface epithelium in that their mucigen granules have slightly different staining qualities and their nuclei tend to be flattened or concave at the base of the cells. (2) The chief cells are found primarily in the lower half of the glands. They have a spherical nucleus and contain light-refracting granules and a Golgi apparatus, the size and form of which vary with the state of secretory activity. They produce pepsinogen, the precursor of pepsin, a digestive enzyme. (3) Parietal cells are larger and usually clustered away from the gland’s lumen, to which they connect by small gaps stemming from intra-cellular canaliculi. Their intraplasmatic granules are strongly eosinophilic; they refract light less than chief cells do. Parietal cells produce the hydrochloric acid that lowers the pH in the stomach. They also produce intrinsic factor, a glycoprotein that allows vitamin B12 to be absorbed further along in the ileum of the gastrointestinal tract. (4) Enteroendocrine cells are isolated glandular cells that release hormones into the lamina propria to modulate activity of the stomach and other digestive organs. Each enteroendocrine cell in the stomach may secrete gastrin (C cells), ghrelin, bombesin, enkephalins, vasoactive intestinal peptide, or somatostatin (D cells). Enterochromaffin-like cells secrete histamine, and enterochromaffin cells secrete serotonin. Different hormones are released by enteroendocrine cells elsewhere in the gastrointestinal tract. 3. The pyloric glands are located in the pyloric region but also spread into a transitional zone, in which both gastric and pyloric glands are found and which extends diagonally and distally from the lesser to the greater curvature. The tubes of the pyloric glands are shorter, more tortuous, and less densely packed, and their ends are more branched than the fundic glands. Pyloric gland pits are markedly deeper than those in other regions and are lined primarily by mucous cells (as in the cardiac region); occasional parietal or enteroendocrine cells may also be seen.

Mucous membrane, membrane lining body cavities and canals that lead to the outside, chiefly the respiratory, digestive, and urogenital tracts. They line many tracts and structures of the body, including the mouth, nose, eyelids, trachea and lungs, stomach and intestines, and the ureters, urethra, and urinary bladder.

Inflammation of Salivary Glands The major salivary glands and the accessory mucous glands are subject to functional abnormalities as well as inflammation. Amylasemia (ptyalism), or excessive salivation, is associated with the use of several drugs, specifically, clozapine, pilocarpine, and risperidone. Toxins such as mercury, copper, and organophosphates have also been reported to cause excessive salivation. Most often, however, excessive salivation is caused by a form of gastroesophageal reflux known as water brash. On the other hand, xerostomia, or dryness of the mouth, most often results from frequently used medications such as anticholinergic agents, radiation to the head and neck, chemotherapeutic treatment, obstructive sleep apnea, and, less often, Sjögren syndrome, vitamin deficiencies, and other systemic conditions. Inflammation of the major glands is usually shown by swelling and may be a feature of a generalized syndrome. Epidemic parotitis or Hodgkin or leukemic infiltration should be considered diagnostically whenever more than one gland is involved or when a local cause is not obvious. The submandibular gland may be the site of an acute or subacute infection, causing pain on palpation. The swelling differs from that of an alveolar abscess by being deeply seated, not complicated by trismus, and presenting as subepithelial nonadherent swelling beneath the mandible with distinct borders. The orifice of the Wharton duct is reddened, and its course is tender and edematous. Pus may sometimes be expressed by milking the duct. Swelling of the submandibular gland is most often due to obstruction in the form of a salivary calculus. Precipitation of calcium salts is probably initiated by irritation of the duct and stasis of saliva, aided by the presence of a matrix of filamentous colonies of sapro- phytic Actinomyces or other organisms. The parotid gland is subject to similar acute and chronic swellings superimposed on recurrent obstruction of its duct. It may also become infected by an ascending pyogenic infection of the Stensen duct in debilitated or postoperative patients. In this “terminal parotitis,” the onset is sudden, with severe pain, fever, and swelling of the parotid gland. Obstructive parotitis, in contrast to submandibular adenitis, is usually not associated with calculus formation. An inflammatory disturbance in the duct or catarrhal constriction causes characteristic recurrent swelling. Complete obstruction predisposes to abscess formation, with reddening of the skin and a tense, fluctuant swelling of the parotid space. Repeated parotitis may lead to stenosis of the interlobar ducts or main excretory duct. Mumps, a highly contagious viral infection causing parotid gland swelling, usually affects both glands, which have a doughy or elastic consistency. The frequency of this infection had diminished after immunization became available for young children, but now that parents are becoming more resistant to immunizations, the frequency is again increasing. The glands enlarge to the maximum size within 24 to 48 hours and remain enlarged for 7 to 10 days. Microscopically, the glands are heavily infiltrated by lymphocytes and show destruction of acinar cells in varying degrees. The danger of mumps lies in the complications, which include epididymoorchitis, oophoritis, meningoencephalitis, deafness, ocular lesions, and neuritis of the facial and trigeminal nerves.
