- Kidneys.
- Ureters.
- Adrenal/suprarenal glands.
- Abdominal aorta.
- Inferior vena cava.
What are the 5 major folds of the peritoneum?
There are five major peritoneal folds:- the greater omentum, falciform ligament, lesser omentum, mesentery, and mesocolon.
What is frog peritoneum?
Peritoneum is the membrane lining the cavity of abdomen and covers the abdominal organs. There are several types of peritoneal folds which includes mesocolon, mesenteries and omenta. Mesorchium is a mesenteric peritoneal fold that attaches the testes of frog to its kidney.
What are the two folds in the peritoneum?
Two folds are of primary importance: the omentum, which hangs in front of the stomach and intestine; and the mesentery, which attaches the small intestine and much of the large intestine to the posterior abdominal cavity.
What are the 2 layers of the peritoneum?
The peritoneum is comprised of 2 layers: the superficial parietal layer and the deep visceral layer. The peritoneal cavity contains the omentum, ligaments, and mesentery.
What is the difference between omentum and mesentery?
Omentum refers to a fold of peritoneum, connecting the stomach with other abdominal organs while mesentery refers to a fold of the peritoneum, which attaches the stomach, small intestine, pancreas, spleen, and other organs to the posterior wall of the abdomen.
Is retroperitoneal and extraperitoneal same?
Extraperitoneal is the generic concept that comprises the more commonly used terms for the specific locations: retroperitoneal (posterior to the peritonal cavity), subperitoneal (inferior to the peritonal cavity) and preperitoneal (anterior to the peritonal cavity).
What structures are extraperitoneal?
Table 1
| Concept | Discussion |
|---|---|
| The SPS | The SPS is a single extraperitoneal space encompassing the entire abdomen and pelvis. It is divided into regions but remains one interconnected space. The SPS contains all the organs, vessels, lymphatics, and nerves of the abdomen and pelvis. |
What is frog mesentery?
A membrane called the mesentery holds the ileum together. Note the blood vessels running through the mesentery; they will carry absorbed nutrients away from the intestine. Absorption of digested nutrients occurs in the small intestine.
What is cloaca frog?
The frog cloaca is a short simple tube receiving at its inner end the genital and urinary ducts, the rectum, and the allantoic bladder. The female cloaca diners from the male only in the addition of the Mullerian ducts. The ducts open on a ridge of vacuolated tissue marking the boundary of cloaca and rectum.
What are the mesenteries?
The mesentery is a fold of membrane that attaches the intestine to the abdominal wall and holds it in place.
What is mesentery and omentum?
In peritoneum. …are of primary importance: the omentum, which hangs in front of the stomach and intestine; and the mesentery, which attaches the small intestine and much of the large intestine to the posterior abdominal cavity.
What is mesentery peritoneum?
A mesentery is a double layer of peritoneum, and attaches the vasculature and nerves to the intraperitoneal organs. A ligament is made up of two layers of visceral peritoneum and supports one organ or structure within the peritoneal cavity.
Is omentum the same as peritoneum?
The main difference between omentum and peritoneum is that omentum is an abdominal structure formed from the visceral peritoneum with a structure similar to the mesentery whereas peritoneum is the thin, serosal membrane, which lines the abdominal and pelvic cavities, covering most of the viscera.
