Cards

Term
acini cells
Definition
cells that perform exocrine function
Term
amylase
Definition
enzyme secreted by the pancreas to aid in the digestion of carbohydrates
Term
body of the pancreas
Definition
lies in the midepigastrium anterior to the superior mesenteric artery and vein, aorta, and inferior vena cava
Term
Caudal pancreatic artery
Definition
branch of the splenic artery that supplies the tail of the pancreas
Term
C-loop of the duodenum
Definition
forms the lateral border of the head of the pancreas
Term
Common hepatic artery
Definition
forms the right superior border of the body and head of the gland and gives rise to the gastroduodenal artery
Term
Courvoisier's gallbladder
Definition
enlargement of the gallbladder caused by a slow progressive obstruction of the distal common bile duct from an external mass
Term
Cystic fibrosis
Definition
a hereditary disease that causes excessive production of thick mucus by the endocrine glands; identified as fatty replacement of the glands
Term
Dorsal pancreatic artery
Definition

     branch of the splenic artery that supplies the body of the pancreas

Term
Duct of santorini
Definition
small accessory duct of the pancreas found in the head of the pancreas
Term
Duct of Wirsung
Definition
largest duct of the pancreas that drains the tail, body, and head of the gland; it joins the common bile duct to enter the duodenum through the ampulla of vater
Term
Endocrine
Definition
the endocrine function is production of the hormone insulin
Term
exocrine
Definition
production and digestion of pancreatic juice; primary function of the pancreas
Term
Glucagon
Definition

stimulates the liver to convert glycogen to glucose; produced function of

 the pancreas

Term
Head of the pancreas
Definition
lies in the C-loop of the duodenum; the gastroduodenal artery is the anterolateral border and the common bile duct is the posterolateral border
Term
Hypercalcemia
Definition

elevated levels of calcium in

 the blood

Term
Hyperlipidemia
Definition
congenital condition in which elevated fat levels cause pancreatitis
Term
ileus
Definition
dilated loops of bowel without peristalsis; associated with various abdominal problems, including pancreatitis, sickle cell crisis, and bowel obstruction
Term
insulin
Definition
hormone that causes glycogen formation from glucose in the liver and allows cells iwthin insulin receptors to take up glucose to decrease blood sugar
Term
islets of Langerhans
Definition
small cells that comprise the endocrine portion of the pancreas for the production of insulin, glucagon, and somatostatin
Term
Leukocytosis
Definition
an abnormal increase in white blood cells caused by infections
Term
Lipase
Definition
 pancreatic enzyme that breaks down fats; enzyme is elevated in pancreatits and remains increased longer than amylase
Term
Lymphoma
Definition
a malignant neoplasm that rises from the lymphoid tissues
Term
neck of pancreas
Definition
small area of the pancreas between the head and the body; anterior to the superior mesenteric vein
Term
Obstructive jaundice
Definition
Excessive bilirubin in the bloodstream caused by an obstruction of bile from the liver; characterized by a yellow discoloration of the sclera of the eye, skin, and mucous membranes
Term
Pancreatic ascites
Definition
occurs when the pancreatic pseudocyst ruptures into the abdomen; free-floating pancreatic enzymes are vary dangerous to surrounding structures
Term
Pancreatic pseudocyst
Definition
"sterile abscess" collection of pancreatic enzymes that accumulate in the available space in the abdomen (usually in or near pancreas)
Term
Pancreaticoduodenal arteries
Definition

help supply blood to the pancreas along with

the splenic artery

Term
Pancreatitis
Definition
inflammation of the pancreas; may be acute or chronic
Term
Portal-splenic confluence
Definition

    junction of the splenic and main portal vein; posterior border of the body of the pancreas

Term
Pseudocyst
Definition
a space or cavity that contains fluid but has no true endothelial lining membrane
Term
serum amylase
Definition
pancreatic enzyme that is elevated during pancreatitis
Term
Superior mesenteric artery
Definition

  serves as the posterior border to the body

 of the pancreas

Term
Superior mesenteric vein
Definition
lies posterior to the neck/body of the pancreas and anterior to the uncinate process of the gland
Term
tail of the pancreas
Definition
tapered end of the pancres that lies in the left hypochondrium near the hilus of the spleen and upper pole of the left kidney
Term
uncinate process
Definition
small, curved tip of the pancreatic head that lies posterior to the superior mesenteric vein
