What passes through the hepatoduodenal ligament?
What passes through the hepatoduodenal ligament?
The hepatoduodenal ligament runs from the porta hepatis to the proximal 2 cm of the duodenum. The hepatic artery proper, common bile duct, and portal vein run through the ligament near its free edge to reach the liver. These three structures are often referred to as the portal triad.
Which structures are contained within the hepatoduodenal ligament?
The hepatic artery proper bifurcates near the porta hepatis divides into the right and left hepatic arteries that enter the liver. At this point, the artery finally bifurcates into the right and left hepatic arteries, however there are some common anatomical variations of this part of the vessel.
What is in the hepatogastric ligament?
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.
What are the contents of porta hepatis?
The porta hepatis is the central intraperitoneal fissure of the liver that separates the caudate and the quadrate lobes. It is the entrance and the exit for several important vessels including the portal vein, the hepatic artery, the hepatic nervous plexus, the hepatic ducts and the lymphatic vessels.
What is Gastrophrenic ligament?
Gastrophrenic ligament. (Science: anatomy) The portion of the greater omentum that extends from the greater curvature of the stomach to the inferior surface of the diaphragm. Synonym: ligamentum gastrophrenicum, gastrodiaphragmatic ligament, phrenogastric ligament.
Which of the following is the most posteriorly located structure within the hepatoduodenal ligament?
The main portal vein courses cranially toward the liver as the most posterior structure within the hepatoduodenal ligament to divide into the left and right portal veins near the liver hilum. A small branch to the right side of the caudate is commonly encountered just before or after the main portal vein branching.
What is Hepatogastric?
[ hĕp′ə-tō-găs′trĭk ] adj. Relating to the liver and the stomach.
What is the role of Ligamentum Venosum?
The ligamentum venosum serves primarily as a landmark and source of controlling the left hepatic vein during dissections that require control of the vessel.
Is the porta hepatis covered by peritoneum?
The surface of the liver is covered by visceral peritoneum (serosa), with a Glisson capsule underneath. At the porta hepatis, the Glisson capsule travels along the portal tracts (triads), carrying branches of the hepatic artery, the portal vein, and the bile ducts into the liver substance.
How do you remember porta hepatis?
Mnemonic
- D: ducts (right and left hepatic duct branches)
- A: arteries (right and left hepatic artery branches)
- V: vein (portal vein)
- E: epiploic foramen (of Winslow)
What does the Gastrophrenic ligament connect?
The posterior surface of the esophagus and stomach are devoid of peritoneum close to the gastroesophageal (GE) junction and phrenicoesophageal ligament is attached to the posterior surface of the esophagus while the gastrophrenic ligament is attached to the posterior surface of the stomach.
Where is the Gastrophrenic ligament?
stomach
(Science: anatomy) The portion of the greater omentum that extends from the greater curvature of the stomach to the inferior surface of the diaphragm.
