What is a intraperitoneal organ?
Intraperitoneal organs include the stomach, spleen, liver, first and fourth parts of the duodenum, jejunum, ileum, transverse, and sigmoid colon. The mesentery helps attach the abdominal organs to the abdominal wall and contains many blood vessels, nerves, and lymphatics.
What are intraperitoneal and retroperitoneal organs?
The structures within the intraperitoneal space are called “intraperitoneal” (e.g., the stomach and intestines), the structures in the abdominal cavity that are located behind the intraperitoneal space are called “retroperitoneal” (e.g., the kidneys), and those structures below the intraperitoneal space are called ” …
Where are intraperitoneal organs located?
Intraperitoneal Structures Intraperitoneal organs include the stomach, the first five centimeters and the fourth part of the the duodenum, the jejunum, the ileum, the cecum, the appendix, the transverse colon, the sigmoid colon, and the upper third of the rectum.
What are Extraperitoneal organs?
Extraperitoneal structures are outside the peritoneal cavity. They have been lying outside the peritoneal cavity from the very beginning of the embryological development. The vertebrae, aorta and inferior vena cava (IVC), and kidneys lie posterior to the peritoneum: they lie retroperitoneally.
What is the difference between peritoneum and omentum?
The peritoneum is a serous membrane that lines the abdomino-pelvic cavity and supports and protects abdominal organs. Omentum, on the other hand, is a fold of the peritoneum. Omenta form connections between the stomach and the duodenum. Peritoneum divides further as the visceral peritoneum and the parietal peritoneum.
What is the medical term for intraperitoneal?
Intraperitoneal means within or administered through the peritoneum. The peritoneum is a thin, transparent membrane that lines the walls of the abdominal (peritoneal) cavity and contains/encloses the abdominal organs such as the stomach and intestines. Intraperitoneal is often abbreviated I.P. or IP.
What is the function of the perineum?
The perineum is the area between the genitals and the anus. 7 It supports the pelvic floor, the bottom of the pelvic cavity that holds your intestines, bladder, and other internal organs. Muscles and nerves that run through this small area control sexual function and the urinary and excretory systems.
What is the perineum made of?
The perineum includes all of the soft tissue caudal to the pelvic diaphragm. The deep perineum of both sexes includes the muscular external anal sphincter and the urogenital diaphragm which includes the voluntary sphincter for the urethra (Figure 4.12F).
What happens when you have your omentum removed?
Although an omentectomy is a relatively safe procedure, complications can arise. Complications can include: Pain. Lymphedema – buildup of fluid caused by lymph-vessel blockage.
Which organs are extraperitoneal?
Some organs grow in the intraperitoneal space during fetal period but become extraperitoneal during later development.These organs are called Secondary retroperitoneal organs. eg:Duodenum,pancreas,Ascending Colon,Descending colon.
What organs lie within the peritoneum?
The kidneys, adrenal glands, bladder and ureters are called retroperitoneal organs because they lie behind the peritoneum. The nerve supply to the parietal peritoneum makes it sensitive to pain. It is common for cancers to originate elsewhere and for the tumor cells to spread, or metastasize, to the peritoneum.
What is the difference between intraperitoneal and retroperitoneal?
The key difference between the intraperitoneal and the retroperitoneal organs is the location of the organs. Intraperitoneal organs are situated in the intraperitoneal space and lined by the peritoneum , whereas retroperitoneal organs are situated behind the intraperitoneal space and not lined by the peritoneum.
What are the primary retroperitoneal organs?
There are two types of retroperitoneal organs: Primary retroperitoneal and Secondary retroperitoneal. Primary retroperitoneal: These are structures which are retroperitoneal from the start of their development. These include: Urinary structures. Suprarenal glands. Kidneys. Ureters.
