Translations
pylorus
pylorus[pə′lȯr·əs] (anatomy) The orifice of the stomach communicating with the small intestine. pylorus
pylorus [pi-lor´us] the distal aperture of the stomach, opening into the duodenum. The term has also been used to mean the pyloric part of the stomach, and the pyloric antrum, canal, opening, or sphincter. A ring of muscles, the sphincter" >pyloric sphincter, serves as a “gate,” closing the opening from the stomach to the intestine. It opens periodically, allowing the contents of the stomach to move into the duodenum. The pylorus contains many glands that help produce hydrochloric acid. Occasionally, in infants, the pyloric muscle is greatly enlarged and thickened, so that emptying of the stomach is prevented. This condition, hypertrophic pyloric obstruction or stenosis" >pyloric stenosis, can be corrected by surgery.py·lo·rus, pl. py·lor·i (pi-lōr'ŭs, pī-lōr'ī), [TA] 1. The muscular tissue surrounding and controlling the aboral outlet of the stomach. 2. A muscular or myovascular device to open (musculus dilator) and to close (musculus sphincter) an orifice or the lumen of an organ. [L. fr.

At the pylorus, the muscular coats of the stomach wall are thickened to form a strong muscle ring (a SPHINCTER) capable of closing and opening to control the movement of food.PylorusThe ring of muscle that controls the passage of material from the stomach into the small intestine.Mentioned in: Nasogastric Suction, Pyloroplasty, Ulcer Surgerypylorus
