Term
|
Definition
| Structures surrounded by peritoneum. In order to access structures, a surgeon will have to go through at least one layer of peritoneum. |
|
|
Term
|
Definition
| 2 layers of peritoneum suspending an organ (like lung in pleura). Allows structures (arteries, veins, lymphatics, etc.) to go to and from the organ without entering the peritoneum. |
|
|
Term
| Structures supported by two mesenteries |
|
Definition
| Spleen, stomach, and liver. Supported by both a dorsal and ventral mesentery that eventually fuse into one cavity lower in the body. |
|
|
Term
| Movement of gut tube during embryo growth |
|
Definition
| The gut tube migrates to the right (initiated by the liver) and bends at the belly, creating the superior and inferior curvatures of the stomach. With movment of the gut tube, a new space i formed posterior to the stomach which makes up the omental bursa. |
|
|
Term
|
Definition
Comes off of the lesser curvature of the stomach and connects the liver and the stomach in the developing embryo.
1. Hepatogastric ligament (On the left side of the liver posteriorly)
2. Hepatoduodenal ligament (Located at stomach-duodenum intersection. Contains the portal vein, hepatic artery, and common bile duct).
3. Epigloic foramen: connects greater and lesser sacs of stomach. Inferior to the hepatoduodenal ligament. |
|
|
Term
|
Definition
Comes off from greater curvature of the stomach.
Forms:
1. Gastrophrenic ligament (attaches to the diaphragm)
2. Gastrosplenic ligament
3. Gastrocolic ligament (attaches to transverse colon, cut for access to lesser sac)
Variable amounts of fat.
4 layers of peritoneum made up of folded dorsal mesentery. Folded dorsal mesentery fuse against themselves and the transverse colon mesentery.
Has folded recess of omentum bursa lying posterior. |

Anterior: Hepatoduodenal ligament with portal triad |
|
|
Term
| Omental Bursa (lesser sac) |
|
Definition
| Initially to the right of the peritoneal cavity, moves posteriorly with the migration of the stomach and the growth of the liver. Continuous with greater sac at the epiploic foramen. |
|
|
Term
