| pancreas | <anatomy, gastroenterology> A tongue-shaped glandular organ lying below and behind the stomach. The head of the pancreas is encircled by the duodenum and its tail touches the spleen. It secretes the hormones insulin and glucagon (both regulate blood sugar), in addition to pancreatic enzymes involved in the digestion of fats and proteins in the small intestine. (27 Sep 1997) |
| pancreas accessorium | A detached portion of pancreatic tissue, usually the uncinate process, and hence most often found in the vicinity of the head of the pancreas, but may occur within the gut wall (stomach or duodenum). Synonym: pancreas accessorium. Annular pancreas, a ring of pancreas encircling the duodenum, caused by a failure of the embryologic ventral pancreas to migrate to the right of the duodenum.

| Willis' pancreas | A portion of the head of the pancreas that hooks around posterior to the superior mesenteric vessels, sometimes into the "nutcracker" formed by the superior mesenteric artery and abdominal aorta. Synonym: processus uncinatus pancreatis, lesser pancreas, pancreas minus, small pancreas, uncinate pancreas, unciform pancreas, Willis' pancreas, Winslow's pancreas. (05 Mar 2000) |
| mucinous cystic neoplasm of pancreas | <radiology> = macrocystic adenoma of pancreas, cystadenoma / cystadenocarcinoma, M:F = 1:9, 40-60 years of age, malignant or pre-malignant, large mass (mean 12 cm), multilocular cysts, thick septations, tail / body in 85% (unlike adenocarcinoma and microcystic adenoma), hypo-/avascular, Differential diagnosis: panc pseudocyst, ** Cf: microcystic adenoma (12 Dec 1998) |
| Winslow's pancreas | A portion of the head of the pancreas that hooks around posterior to the superior mesenteric vessels, sometimes into the "nutcracker" formed by the superior mesenteric artery and abdominal aorta. Synonym: processus uncinatus pancreatis, lesser pancreas, pancreas minus, small pancreas, uncinate pancreas, unciform pancreas, Willis' pancreas, Winslow's pancreas. (05 Mar 2000) |
| posterior surface of pancreas | The posterior surface of the pancreas. Synonym: facies posterior pancreatis. (05 Mar 2000) |
| head of pancreas | That portion of the pancreas lying in the concavity of the duodenum. Synonym: caput pancreatis. (05 Mar 2000) |
| hepato-pancreas | <marine biology> Digestive gland of crustaceans with functions approximately analogous to liver and pancreas of vertebrates enzyme secretion, food absorption and storage. <zoology> A digestive gland in Crustacea, Mollusca, etc, usually called the liver, but different from the liver of vertebrates.
