A lesion of the mucosal lining of the stomach is called a gastric ulcer.
The enzyme that catalyzes the digestion of peptides in the small intestine is pepsin. Pepsin is released by the mucosal lining of the stomach.
The lining of the stomach has less surface area than the lining of the small intestine. The stomach lining has a mucus coating that protects it from acid while the lining of the small intestine is less coated.
The medical term for an open lesion in the mucous membrane lining of the stomach is "gastric ulcer." Gastric ulcers occur when the protective mucosal barrier is compromised, often due to factors like Helicobacter pylori infection, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), or excessive stomach acid. These ulcers can cause pain and discomfort, and if left untreated, may lead to complications such as bleeding or perforation.
Mucosa
Alcohol and aspirin are the only two substances that can be absorbed directly across the stomach's mucosal epithelium without needing to enter the bloodstream through the small intestine. This is because these substances are lipid-soluble and can pass through the cell membranes of the stomach lining.
In frogs and all other vertebrates lining of stomach and small intestine is made up of mucosa . But mucosa of small intestine possess villi which are finger like projections which increase surface are for absorption .Villi are absent in stomach .the lining in both frogs are think, but the stomach's is shorter than the intestine's In frogs and all other vertebrates lining of stomach and small intestine is made up of mucosa .

Epithelial tissue lines the stomach, like most internal organs.
The mucosa is the lining of the stomach, and the antrum is part of the stomach. Erythema is redness, and an ulceration is an area in which a layer of skin or lining is missing. So "muscosal inflammation in the antrum with erythema and ulcerations" is stomach ulcers.
Gastritis is the inflammation of the lining of the stomach.
The lining of the small intestine is protected from stomach acid by a mucus layer that coats and lubricates the surface. Additionally, the small intestine secretes bicarbonate to help neutralize any acid that enters from the stomach. The rapid turnover of epithelial cells in the intestine also helps to repair and replace damaged cells.
Open sores that occur inside the stomach lining are called ulcers. Having these ulcers frequently is referred to as open sore stomach.
Erosion in the pre-pyloric region refers to the wearing away or breakdown of the mucosal lining of the stomach near the pylorus, which is the opening between the stomach and the small intestine. This erosion can be caused by factors such as excess stomach acid, certain medications, or underlying conditions like gastritis or peptic ulcers. Treatment typically involves addressing the underlying cause and may include medications to reduce stomach acid or promote healing of the stomach lining.
