Definitions

1. The mesentery is a double layer of peritoneum that encircles most of the small intestine and anchors it to the posterior abdominal wall. (Web site)
2. The mesentery is a vital support structure because it contains the blood vessels and nerves that nourish and innervate the bowel. (Web site)
3. The mesentery is an extension of the visceral peritoneum that attaches the small intestine to the rear abdominal wall. (Web site)
4. The mesentery is fan-shaped; its posterior border or root, about 15 cm. (Web site)
5. The mesentery is the white, fibrous, web-like or film-like tissue that connects the various sections of intestines to each other and to the abdominal wall.

Blood Vessels

1. The ventral mesentery disintegrates everywhere except where major blood vessels or visceral organs have grown into it. (Web site)

Layers

1. From the intestinal arteries small branches are given off to the lymph glands and other structures between the layers of the mesentery. (Web site)

Part

1. A colonic volvulus occurs when a part of the colon twists on its mesentery, resulting in acute, subacute, or chronic colonic obstruction.
2. Abdominal portion becomes contained in dorsal mesentery, part of the serosal mesoderm.

Organ

1. Occasionally the whole of the organ is invested by the serous membrane, and is then connected to the liver by a kind of mesentery. (Web site)

Organs

1. Vessels and nerves often lie in the mesentery, where they can easily reach the organ where the peritoneal layers separate and reflect off the organs. (Web site)

Abdominal Cavity

1. In some places it continues beyond as a sheet of tissue called the ventral mesentery, which may hang freely in the abdominal cavity.

Bowel Obstruction

1. The mesentery of the intussusceptum is invaginated with the intestine, leading to the classic pathophysiologic process of any bowel obstruction.

Bowel

1. The surgeon sees what the camera sees on a television-type screen and can cut out a large section of the bowel and adjacent tissue, called the mesentery. (Web site)

Narrow Tube

1. Notice that it is a coiled, narrow tube, held together by tissue called mesentery. (Web site)

Bowel Wall

1. In mechanical obstruction of the small bowel, detection of ischemic changes in the bowel wall or mesentery with CT indicates strangulation. (Web site)
2. As the tissue of the bowel wall and the mesentery becomes strangled, it begins to swell, worsening the constriction and hastening the whole process. (Web site)

Sigmoid Colon

1. The mass displaces the sigmoid colon sufficiently to result in torsion of the mesentery and a resultant volvulus.

Transverse Colon

1. Only part suspended on mesentery is transverse colon c.

Posterior Abdominal Wall

1. On the posterior side, the transverse colon is connected to the posterior abdominal wall by a mesentery known as the transverse mesocolon.
2. The embryonic right colon typically has a mesentery that eventually fuses to the parietal peritoneum, resulting in adherence to the posterior abdominal wall.

Abdomen

1. On the other hand, the transverse and sigmoid colon are supported by a mesentery in the abdomen.
2. Regarding the abdomen: (a) By the fifth week of fetal life the gut tube within the peritoneal cavity is suspended by the dorsal mesentery. (Web site)

Colon

1. Lack of fixation of the mesentery of the colon and duodenum results in the formation of potential hernial pouches. (Web site)

Small Intestine

1. The mesentery of the small intestine arises from the root of the mesentery which extends from the duodenojejunal flexure to the ileocecal junction. (Web site)

Intestine

1. This can cause mesenteric ischemia (mesentery=lining of the bowel + ischemia=loss of blood supply) and potential necrosis (tissue death) of the intestine. (Web site)
2. They are placed lengthwise in the intestine, and are situated in the portion of the tube most distant from the attachment of the mesentery. (Web site)
3. The next lymph sac to appear is the unpaired retroperitoneal lymph sac at the root of the mesentery of the intestine. (Web site)

Small Bowel

1. The right inframesocolic compartment is bounded by the transverse colon and the root of the small bowel mesentery. (Web site)
2. The mass tends to develop in abdominal incisions, in the abdominal cavity (particularly the small bowel mesentery), and the retroperitoneum. (Web site)
3. Also, if the small bowel and colon have not rotated properly, the mesentery may be only narrowly attached to the back of the abdominal cavity. (Web site)

Cecum

1. Between the mesentery and the cecum and ascending colon is the right medial paracolic gutter.

Volvulus

1. Volvulus refers to the twisting of a portion of the intestine around itself or a stalk of mesentery tissue to cause an obstruction. (Web site)
2. In developing countries, a high-fiber diet results in overloading of the sigmoid colon, which twists around its mesentery and results in volvulus.
3. The small bowel mesentery in this case is a narrow pedicle and allows volvulus of the whole small intestine – volvulus neonatorum. (Web site)

Spleen

1. The spleen develops from mesenchymal cells between layers of the dorsal mesentery of the stomach. (Web site)

Largest Organ

1. The spleen is the largest organ derived from mesenchyme and lying in the mesentery. (Web site)

Abdominal Wall

1. The ileum is suspended from the abdominal wall by the mesentery. (Web site)
2. The lining of the small bowel mesentery (membrane that joins small intestine to back of abdominal wall) becomes thickened and inflamed.
3. Rarely, these blood vessels persist in the form of fibrous remnants that run between the Meckel diverticulum and the abdominal wall or small bowel mesentery. (Web site)

Peritoneum

1. Organs, like most of the intestine, that are almost completely invested by peritoneum are connected to the body wall by a mesentery. (Web site)
2. Prather C. Inflammatory and anatomic diseases of the intestine, peritoneum, mesentery, and omentum.
3. It is the shortest, the widest, and the most fixed part of the small intestine, and has no mesentery, being only partially covered by peritoneum. (Web site)

Mesentery

1. The jejunum and the ileum are suspended by mesentery which gives the bowel great mobility within the abdomen. (Web site)
2. The peritoneal reflection to the jejunum and ileum is termed the mesentery, whereas those to the colon are each known as a mesocolon. (Web site)
3. The cecum, transverse colon, and sigmoid colon are suspended from the back of the abdominal wall by the mesentery. (Web site)
