dull, sickening, poorly localized to midline
Term
referred pain
Definition
pain in a cutaneous region of the body that shares a dermatome with the diseased organ
Term
falciform ligament
Definition
suspends the liver from the anterior abdominal wall
Term
coronary ligament
Definition
suspends the liver from the diaphragm, consists of anterior and posterior layers of peritoneum
Term
porta hepatis
Definition
the crossbar of the "H", portal vein and hepatic artery proper enter the liver, right and left hepatic ducts exit the liver
Term
bare area of the liver
Definition
small, posterosuperior region of the liver's exterior which is not covered with peritoneum

Term
hepatopancreatic ampulla
Definition
unity of common bile duct with main pancreatic duct at 2nd part of duodenum, opens into the duodenum at the major duodenal papilla, encircled by hepatopancreatic sphincter
Term
pancreas
Definition
head, neck and body are secondarily retroperitoneal; tail is intraperitoneal
Term

Definition
peritoneal ligament that extends from the visceral surface of the liver to the lesser curvature and upper border of proximal half of 1st part of duodenum
Term
greater omentum of stomach
Definition
arises from the greater curvature and the lower border of the proximal half of the 1st part of the duodenum
Term
1st part of duodenum
Definition
extends to the right as it lies above the head of the pancreas
Term
2nd part of duodenum
Definition
extends downward as it lies to the right of the head of the pancreas
Term
3rd part of duodenum
Definition
extends to the left as it lies below the head of the pancreas
Term
4th part of duodenum
Definition
extends to the left and upward as it lies below the head and neck of the pancreas
Term
duodenum
Definition
all except proximal half of 1st part (intraperitoneal) is retroperitoneal, extends from pylorus of stomach to duodenojejunal flexure, C-shaped around head, neck and body of pancreas
Term
celiac artery origin
Definition
abdominal aorta just below the aortic opening of the diaphragm
Term
celiac artery branches
Definition
1) left gastric
2) splenic
3) common hepatic
Term
left gastric artery
Definition
esophageal branches to lower third of esophagus, and gastric branches to upper part of lesser curvature of stomach
Term
splenic artery
Definition
largest branch of celiac artery, supplies body and tail of pancreas, short gastric arteries to fundus of stomach, splenic branches to spleen, left gastroepiploic artery to upper part of greater curvature of stomach
Term
