MÃ©nÃ©trierâs Disease What is Ménétrier’s disease? Ménétrier’s disease causes the ridges along the inside of the stomach wall—called rugae—to enlarge, forming giant folds in the stomach lining. The rugae enlarge because of an overgrowth of mucous cells in the stomach wall. In a normal stomach, mucous cells in the rugae release protein-containing mucus.

StomachËstÉm-Ék, -ik The cells lining the stomach secrete three important substances: mucus, hydrochloric acid, and the precursor of pepsin (an enzyme that breaks down proteins). Mucus coats the cells of the stomach lining to protect them from being damaged by acid and enzymes.

Layers of the Stomach This outermost layer of the stomach is a thin membrane that protects the stomach from other organs and the motion of the food inside. It is a thin membrane made up of areolar connective tissue and squamous epithelial tissue. This video offers much more information on the layers of the stomach:

What do I Need to Know About my Stomach Lining? 10 most extreme places on Earth. The lining of the stomach is a rather unique anatomical feature. The stomach is essentially an enlarged area of intestines turned into a bag which holds acids and other substances which help people digest their food. The stomach lining is responsible for secreting substances used in digestion, and for protecting the rest of the body from the highly acidic environment of the stomach.

Greater omentum The greater omentum (also the great omentum, omentum majus, gastrocolic omentum, epiploon, or, especially in animals, caul) is a large apron-like fold of visceral peritoneum that hangs down from the stomach.t extends from the greater curvature of the stomach, passing in front of the small intestines and reflects on itself to ascend to the transverse colon before reaching to the posterior abdominal wall. The greater omentum is larger than the lesser omentum which hangs down from the liver to the lesser curvature.

urinary bladder The inner lining of the urinary bladder is a mucous membrane of transitional epithelium that is continuous with that in the ureters. When the bladder is empty, the mucosa has numerous folds called rugae. The rugae and transitional epithelium allow the bladder to expand as it fills.

The double layer of peritoneum which covers abdominal organs and suspends the small intestine south of the ligament of Treitz—i.e., the jejunum and the ileum.he fan-shaped fold of peritoneum suspending the greater part of the small intestines (jejunum and ileum) and attaching it to the posterior abdominal wall at the root of the mesentery (radix mesenterii).

Anatomy of the Stomach In the empty state, the stomach is contracted and its mucosa and submucosa are thrown up into distinct folds called rugae; when distended with food, the rugae are ironed out and flat. The image above shows rugae on the surface of a dog's stomach. If the lining of the stomach is examined with a hand lens, one can see that it is covered with numerous small holes. These are the openings of gastric pits which extend into the mucosa as straight and branched tubules, forming gastric glands.

- Now concentrate on the cells and folding of the mucosal epithelium: 1  Surface epithelium: The surface of the stomach is lined by simple columnar cells that secrete mucus. 2  Pits: The wide-bore, funnel shaped pits are also lined by mucus-secreting cells which become shorter as one progresses deeper into the pit.

Stomach Corpus - The largest part of the stomach is the corpus (or body), which forms the lesser curvature (cranial) and the greater curvature (caudal). Pyloric part - The corpus is followed by the pyloric part, which is perpendicular to the long axis of the stomach. The pylorus sphincter marks the lower end of the stomach and the entrance to the duodenum. Microscopic Anatomy. Histologically the stomach wall is divided into five layers. 1  From superficial to deep there is the: 2  Serosa (peritoneum) 3  Subserosa. 4  Muscularis externa - It consists of an external longitudinal, a middle circular and an inner oblique layer. 5  Submucosa - This layer consists of loose connective tissue with large blood vessels.

Stomach Located between the esophagus and the duodenum, the stomach is a roughly crescent-shaped enlargement of the gastrointestinal tract. The inner layer of the stomach is full of wrinkles known as rugae (or gastric folds).

The stomach and its role in digestion The mucosa and the sub-mucosa are present as folds termed rugae. When the stomach is distended with food, the rugae are flattened out and appear smooth. Cell types in the stomach that help with digestion. There are four main types of cells for stomach secretions spread all over the inner surface of the stomach:

What Is Stomach Cancer? 1 This is where stomach acid and digestive enzymes are made. 2  Most stomach cancers start in this layer. 3  Next is a supporting layer called the submucosa. 4  Outside of this is the muscularis propria, a thick layer of muscle that moves and mixes the stomach contents.hen the term stomach cancer or gastric cancer is used, it almost always refers to an adenocarcinoma. These cancers develop from the cells that form the innermost lining of the stomach (known as the mucosa).

Gastritis The stomach has an internal lining, or mucous membrane, called the gastric mucosa. The mucosa must create hydrochloric acid to break down food, but also protect itself from the acidic contents that it creates. This delicate balance is controlled by three different glands in the lining of the stomach.

sus2 and sus4 Chords Sus is an abbreviation for suspended, it refers to chords that don't follow the common triad pattern, whether major or minor triads, of 1 (root)+ 3 + 5. There are two commonly used types of suspended chords: sus4 - A sus4 chord replaces the 1+3+5 pattern with 1+4+5, meaning the third note is replaced by the fourth. For example, the tab says you need to play a Dsus4 chord, instead of playing D+F#+A (=1+3+5) you raise the middle note or the third note by a half step.

Stomach After eating, these folds flatten, and the stomach is able to distend greatly. The stomach has three anatomical regions: cardiac, which contains mucous secreting glands (called cardiac glands) and is closest to the oesophagus. fundus, the body or largest part of the stomach which contain the gastric (fundic) glands.

Greater omentum The greater omentum is the largest of the two peritoneal folds. It consists of a double sheet of peritoneum, folded on itself so that it has four layers. The two layers of the greater omentum descend from the greater curvature of the stomach and the beginning of the duodenum.

Structure of the Digestive Tract Wall The visceral peritoneum is the serous membrane that lines the stomach, large intestine, and small intestine. The mesentery is an extension of the visceral peritoneum that attaches the small intestine to the rear abdominal wall.

What Is Stomach Cancer? The stomach wall has 5 layers: 1  The innermost layer is the mucosa. 2  Next is a supporting layer called the submucosa. 3  Outside of this is the muscularis propria, a thick layer of muscle that moves and mixes the stomach contents. 4  The outer 2 layers, the subserosa and the outermost serosa, wrap the stomach. Body (corpus): The main part of the stomach, between the upper and lower parts. 2  Antrum: The lower portion (near the intestine), where the food is mixed with gastric juice. 3  Pylorus: The last part of the stomach, which acts as a valve to control emptying of the stomach contents into the small intestine.
