Is the omentum part of the digestive system?
The omentum is a membranous double layer of fatty tissue that covers and supports the intestines and organs in the lower abdominal area. The omentum is made up of the greater omentum which is an important storage for fat deposits and the lesser omentum which connects the stomach and intestines to the liver.
What system is the greater omentum in?
The greater omentum is formed along the greater curvature of the stomach by the union of the peritoneal layers of the anterior and posterior gastric surfaces. On its left it condenses into the gastrosplenic omentum, containing the short gastric branches of the splenic artery between its two layers (Fig.
What organs does the greater omentum attach to?
The omentum attaches ventrally to the greater curvature of the stomach and dorsally to the greater curvature of the stomach and the pancreas and spleen. The blood supply derives from peripheral vessels of the right and left gastroepiploic arteries.
Is the omentum part of the mesentery?
The main difference between omentum and mesentery is that omentum is a fatty blanket hanging down in front of all the intestines, whereas mesentery is the supporting tissue to both small and large intestines. Omentum and mesentery are two tissues that originate from the peritoneum of the abdominal cavity.
What is the purpose of omentum?
The Omentum is a large flat adipose tissue layer nestling on the surface of the intra-peritoneal organs. Besides fat storage, omentum has key biological functions in immune-regulation and tissue regeneration.
What is the role of the omentum?
Therefore, the omentum has been recognised as having an important role in the immune defence, specifically in the peritoneal cavity. It plays this role by adhering to sites of inflammation, absorbing bacteria and other contaminants, and providing leukocytes for the local immune response .
What is the function of the omentum?
Besides fat storage, omentum has key biological functions in immune-regulation and tissue regeneration. Omentum biological properties include neovascularization, haemostasis, tissue healing and regeneration and as an in vivo incubator for cells and tissue cultivation.
Does the omentum have nerves?
The omenta are folds of peritoneum enclosing nerves, blood vessels, lymph channels, and fatty and connective tissue.
Can the omentum cause pain?
INTRODUCTION. Torsion of the greater omentum is a rare, benign cause of acute abdominal pain, caused by twisting of the omentum around a pivotal point, usually in a clockwise direction .
What purpose does the omentum serve?
The omentum. It’s a curtain of fatty tissue that hangs down from our stomach and liver and wraps around the intestines, and is known to play a role in immune responses and metabolism, although exactly how that happens is only dimly understood.
