In human anatomy, the mesentery, an organ that attaches the intestines to the posterior abdominal wall, comprises the double fold of the peritoneum. It helps in storing fat and allowing blood vessels, lymphatics, and nerves to supply the intestines.
The cystic duct is the duct that (typically) joins the gallbladder and the common hepatic duct; the union of the cystic duct and common hepatic duct forms the bile duct. Its length varies.
In anatomy, the gastroduodenal artery is a small blood vessel in the abdomen. It supplies blood directly to the pylorus and proximal part of the duodenum. It also indirectly supplies the pancreatic head.
The lesser omentum is the double layer of peritoneum that extends from the liver to the lesser curvature of the stomach, and to the first part of the duodenum. The lesser omentum is usually divided into these two connecting parts: the hepatogastric ligament, and the hepatoduodenal ligament.
The left gastroepiploic artery, the largest branch of the splenic artery, runs from left to right about a finger's breadth or more from the greater curvature of the stomach, between the layers of the greater omentum, and anastomoses with the right gastroepiploic.
The right gastric artery usually arises from the proper hepatic artery. It descends to the pyloric end of the stomach before passing from right to left along its lesser curvature, supplying it with branches, and finally anastomosing with the left gastric artery.
The superior pancreaticoduodenal artery is an artery that supplies blood to the duodenum and pancreas.
The greater omentum is a large apron-like fold of visceral peritoneum that hangs down from the stomach. It extends from the greater curvature of the stomach, passing in front of the small intestines and doubles back to ascend to the transverse colon before reaching to the posterior abdominal wall. The greater omentum is larger than the lesser omentum, which hangs down from the liver to the lesser curvature. The common anatomical term "epiploic" derives from "epiploon", from the Greek epipleein, meaning to float or sail on, since the greater omentum appears to float on the surface of the intestines. It is the first structure observed when the abdominal cavity is opened anteriorly.
The gastrocolic ligament is a portion of the greater omentum that stretches from the greater curvature of the stomach to the transverse colon. It forms part of the anterior wall of the lesser sac.
The broad ligament of the uterus is the wide fold of peritoneum that connects the sides of the uterus to the walls and floor of the pelvis.
The duodenojejunal flexure or duodenojejunal junction, also known as the angle of Treitz, is the border between the duodenum and the jejunum.
The suspensory ligament of the ovary, also infundibulopelvic ligament, is a fold of peritoneum that extends out from the ovary to the wall of the pelvis.
The lateral umbilical fold is an elevation of the peritoneum lining the inner/posterior surface of the lower anterior abdominal wall formed by the underlying inferior epigastric artery and inferior epigastric vein which the peritoneum covers. Superiorly, the lateral umbilical fold ends where the vessels reach and enter the rectus sheath at the arcuate line of rectus sheath; in spite of the name, the lateral umbilical folds do not extend as far superiorly as the umbilicus. Inferiorly, it extends to just medial to the deep inguinal ring.
The lesser tubercle of the humerus, although smaller, is more prominent than the greater tubercle: it is situated in front, and is directed medially and anteriorly.
In human anatomy, the median umbilical ligament is an unpaired midline ligamentous structure upon the lower inner surface of the anterior abdominal wall. It is covered by the median umbilical fold.
The hepatogastric ligament or gastrohepatic ligament connects the liver to the lesser curvature of the stomach. It contains the right and the left gastric arteries. In the abdominal cavity, it separates the greater and lesser sacs on the right. It is sometimes cut during surgery in order to access the lesser sac. The hepatogastric ligament consists of a dense cranial portion and the caudal portion termed the pars flaccida.
The left triangular ligament is a large peritoneal fold. It connects the posterior part of the upper surface of the left lobe of the liver to the thoracic diaphragm.
The gastrosplenic ligament is part of the greater omentum extending between the stomach and the spleen. It contains several blood vessels.
In human anatomy, the omental foramen is the passage of communication, or foramen, between the greater sac, and the lesser sac of the peritoneal cavity.
Peritoneal recesses are the spaces formed by peritoneum draping over viscera.
