eMedicine - Carcinoma of the Ampulla of Vater : Article Excerpt by: Pankaj Chaturvedi, MBBS, MS Background: Carcinoma of the ampulla of Vater is a malignant tumor arising within 2 cm of the distal end of the common bile duct, where it passes through the wall of the duodenum and ampullary papilla. The most distal portion of the common bile duct is dilated (ie, forms the ampulla of Vater) and is surrounded by the sphincter of Oddi, which spirals upward around the terminal portion of the duct. Because of biliary outflow obstruction, carcinoma of the ampulla of Vater tends to manifest early, as opposed to other pancreatic neoplasms that often are advanced at the time of diagnosis. www.emedicine.com /med/byname/carcinoma-of-the-ampulla-of-vater.htm   (560 words)

Hepatopancreatic ampulla - Wikipedia, the free encyclopedia The hepatopancreatic ampulla, also commonly called the "Ampulla of Vater," is an opening in the wall of the descending duodenum formed by the union of the pancreatic duct and the bile duct. Various smooth muscle sphincters regulate the flow of bile and pancreatic juice through the ampulla: the sphincter of the pancreatic duct, the sphincter of the bile duct, and the hepatopancreatic sphincter (sphincter of Oddi). The eponymical term "Ampulla of Vater" is named after Abraham Vater (1684-1751), a German anatomist who first published a description of it in 1720. en.wikipedia.org /wiki/Ampulla_of_Vater   (162 words)

If the head moves in such a way to cause fluid to move from the semicircular canal through the ampulla and toward the utricle, the stereocilia will easily bend as they are not "protected" by the kinocilium. However, this time the fluid is moving from the utricle side of the ampulla into the semicircular canal due to the movement of the head in space. www.uwm.edu /~tking/king6_8.htm   (203 words)

Pilgrim Signs and Religious Goods from Billy and Charlie - Ampullae Ampullae were commonly distributed at shrines which had sources of sacred or thaumaturgically active water. To produce these ampullae, a mold with a large cavity is filled up entirely with molten metal, then as the metal starts to freeze from the outside first, the still molten center of the pool is poured back out, leaving a hollow shell. The inscription on this spectacular ampulla can be translated "Thomas is the best doctor of the worthy sick." Pilgrims to Canterbury would have taken home water from the shrine in an ampulla like this one, then saved it until the day when it was needed as a specially powerful medicine. www.billyandcharlie.com /ampul.html   (299 words)

FRS: Uterine Tubes The ampulla is the middle, one-third region in which fertilization usually occurs. The ovum moves down the infundibulum of the uterine tube toward the ampulla, assisted by peristaltic contractions of the smooth muscle in the wall of the tube as well as fluid moved by ciliated epithelial cells in the mucosa of the tube. The tunica muscularis is sparse in the infundibulum and the ampulla but thick in the isthmus consisting of an inner circular and an outer longitudinal layer of smooth muscle. www.cvm.okstate.edu /instruction/mm_curr/histology/fr/HiFRp12.htm   (1062 words)
