Where do the nerves that supply the peritoneum come from?

The transverse mesocolon fuses with what?
the posterior layer of the greater omentum
Which mesenteries are lost during development?
duodenum, ascending colon, descending colon and cecum
True or False?
Peritoneal ligaments usually transmit nerves and vessels
true
What is the greater omentum?
broad, 2-4-layered sheet of peritoneum that attaches the stomach to other viscera
The lesser omentum is subdivided into what two ligaments?
hepatogastric ligament
hepatoduodenal ligament
Coronary ligaments, right and left triangular ligaments, falciform ligament, ligamentum treres hepatic are all peritoneal ligaments associated with what?
the liver
What is a fold?
a ridge or elevation in the peritoneum produced by underlying vessels
