The mesentery of the small intestine arises from the root of the mesentery (or mesenteric root) and is the part connected with the structures in front of the vertebral column. The root is narrow, about 15 cm long, 20 cm in width, and is directed obliquely from the duodenojejunal flexure at the left side of the second lumbar vertebra to the ...

The comb sign is a radiological sign seen on computed tomography or magnetic resonance imaging scans, primarily used to identify inflammation in the mesentery. [1] It refers to the appearance of engorged mesenteric vessels resembling the teeth of a comb, which is a key feature seen in several abdominal conditions, particularly those associated with inflammatory bowel diseases, such as Crohn's ...
These parts of the tract have a mesentery. Regions of the gastrointestinal tract behind the peritoneum (called retroperitoneal ) are covered with adventitia . They blend into the surrounding tissue and are fixed in position (for example, the retroperitoneal section of the duodenum usually passes through the transpyloric plane ).
In the short, upper part of the mesentery only one set of arches exists, but as the depth of the mesentery increases, second, third, fourth, or even fifth groups are developed. The differences between the ileal arteries and the jejunal arteries can be summarized as follows: [ 1 ]
The superior mesenteric glands receive lymph from the jejunum, ileum, cecum, vermiform process, and the ascending and transverse parts of the colon; lymph drains into the preaortic glands. Additional images
The duodenal bulb is a remnant of the mesoduodenum, a mesentery that suspends the organ from the posterior abdominal wall in fetal life. [10] The first part of the duodenum is mobile, and connected to the liver by the hepatoduodenal ligament of the lesser omentum. The first part of the duodenum ends at the corner, the superior duodenal flexure.
In the anatomy of the human digestive tract, there are two colic flexures, or curvatures in the transverse colon. The right colic flexure is also known as the hepatic flexure, and the left colic flexure is also known as the splenic flexure. [1] Note that "right" refers to the patient's anatomical right, which may be depicted on the left of a ...
