📌THE PERITONEUM The Peritoneum is a thin serous membrane that lines the wall of the abdominal cavity and invests the viscera organs. Note: Deep to The extraperitoneal fascia(a fascia covering the peritoneum), is the peritoneum which is a membrane lining the abdominal cavity and investing the viscera, More superficial to the extraperitoneal fascia is the Transversalis fascia. 👉Parts of the Peritoneum -Parietal Part -Visceral Part ⏺Parietal part; is the part of the peritoneum that lines the walls of the Abdominal cavity. ⏺Visceral Part; is the part of the peritoneum that invests the abdominal organs ⏺The cavity between the Parietal and visceral part is the peritoneal cavity which is filled with a fluid called peritoneal fluid that allows free movement of both part on each other. ⏺Organs that are found between the parietal part and extraperitoneal fascia are called Retroperitoneal organs and they include kidneys, ureters, suprarenal glands, ascending and descending colon etc. ⏺Organs that are invested by the visceral part are called intraperitoneal organs e.g. Stomach, liver, pancreas, gall bladder etc ⏺The Peritoneal cavity is divided into two parts/sacs --The Greater sac; which begins superiorly from the diaphragm and end in the pelvic cavity inferiorly. --The Lesser sac or the Omental Bursa; which is found at the posterior surface of the stomach and liver. It continues as the greater sac at the omental foramen or epiploic foramen. ⏺Boundaries of the Omental foramen. --Anteriorly by the hepatic vein, hepatic artery proper and bile duct --Posteriorly by the inferior Vena Cava --Superiorly by the caudate lobe of the liver --Inferiorly by the first part of the Duodenum 🌬Knowledge is not power, it's just the essential of power.
