The ligament of Treitz:
- Contracts to help the contents of the intestines move along.
- Helps anchor the duodenum (first part of the small intestine, just after the stomach).
- Is an important landmark in human anatomy, especially for surgeons. It forms the boundary between the upper GI tract to the lower GI tract and helps define what classifies as ...
What is the Tering of ligament at the joint?
Sprains and strains, from twisted ankles to aching backs, are among the most common injuries. A sprain is a stretching or tearing of ligaments, the tough, fibrous bands of tissue that connect bones to one another at a joint. A strain is a stretching or tearing of a tendon or muscle tissue, commonly called a pulled muscle.

What is patella ligament?
The patellar tendon is the structure that connects the kneecap (patella) to the shinbone (tibia). A ligament is a structure that connects one bone to another bone, and therefore some people refer to this as the patellar ligament.
What vertebral level is the ligament of Treitz?
The ligament most commonly (in 40–60% of cases) attaches to the third and fourth parts of the duodenum and the duodenojejunal flexure at the level of the inferior border of the first lumber vertebra (Fig. 2A). In 31–53% of cases, the ligament attaches to the third and fourth parts of the duodenum only (Fig.

Who is Treitz?
Treitz is remembered for his 1853 description of the suspensory muscle of the duodenum (musculus suspensorius duodeni), later being named the "ligament of Treitz" (also known as Treitz muscle). This ligament is a fibrous structure by which the duodenojejunal junction is fixed to the right crus of the diaphragm.
What separates the upper and lower GI tract?
The exact demarcation between the upper and lower tracts is the suspensory muscle of the duodenum. This differentiates the embryonic borders between the foregut and midgut, and is also the division commonly used by clinicians to describe gastrointestinal bleeding as being of either "upper" or "lower" origin.

What is suspensory ligament in eye?
First described by surgeon Charles Barrett Lockwood, the suspensory ligament of the eye forms a support hammock below the globe extending from the lateral orbital tubercle to the medial canthal tendon. It is formed by the fusion of the capsulopalpebral fascia just anterior to the inferior oblique.
What runs in the Gastrocolic ligament?
The gastrocolic ligament contains the gastroepiploic vessels and associated lymphatics which can help identify the ligament as the fatty plane connecting the stomach to the transverse colon.
Where is ligament of Treitz located?
The ligament of Treitz is a thin band of tissue (peritoneum) that connects and supports the end of the duodenum and beginning of the jejunum in the small intestine. It's also called the suspensory muscle of duodenum.
Which parts of duodenum are retroperitoneal?
first segmentExcept for the first segment, the rest of the duodenum is retroperitoneal and has no mesentery and is fixed to the posterior abdominal cavity.
Is the Oesophagus retroperitoneal?
Retroperitoneal organs lie behind the posterior sheath of the peritoneum and include the aorta, esophagus, second and third parts of the duodenum, ascending and descending colon, pancreas, kidneys, ureters, and adrenal glands.
What is in the hepatoduodenal ligament?
Held within the hepatoduodenal ligament are the bile duct, proper hepatic artery and the hepatic portal vein; collectively known as the portal triad. Like the lesser omentum, the hepatoduodenal ligament is formed by two layers of peritoneum, the visceral peritoneum and the parietal peritoneum.
What is the ligament of Treitz?
The ligament of Treitz is a popular eponym that is used for the suspensory muscle of the duodenum. The ligament of Treitz is actually made up of two separate structures according to the description given in 1853 by Dr. Wenzel Treitz (an Austrian physician).
Where does the second part of the ligament come from?
The second part of the ligament arises as a connective tissue band from the para-aortic connective tissue around the celiac artery. It travels between the pancreas and the splenic vein, as well as the left renal vein. It becomes a triangular structure that inserts at the left lateral aspect of the end of the fourth segment of the duodenum - the duodenojejunal flexure.
What is the DJ flexure?
It passes between the splenic vein, left renal vein and the pancreas to insert at the duodenojejunal flexure (DJ flexure) and part of the inferior aspect of the transverse duodenum. This segment is referred to as the suspensory muscle of the duodenum.
What is the point of transition between the foregut and the midgut?
This is the point of transition between the foregut and the midgut. This becomes clinically relevant when discussing gastrointestinal problems such as gastrointestinal bleeding. Bleeding within the gastrointestinal tract that occurs above the level of the ligament of Treitz is called upper gastrointestinal bleeding. However, if bleeding occurs below the level of this ligament, then it is referred to as lower gastrointestinal bleeding.
What is ligament in abdominal cavity?

Where is the Hilfsmuskel ligament located?
The Hilfsmuskel component of the ligament of Treitz (the first part of the ligament) extends from the right crus of the diaphragm and wraps around the esophageal hiatus. It continues down to the celiac artery where it joins the connective tissue around the area.
Which ligament divides the stomach and attaches to the spleen?
A portion of the greater omentum also leaves the greater curvature of the stomach and attaches to the spleen. This is known as the gastrosplenic or gastrolienal ligament. The two layers of the gastrosplenic ligament divide at the hilum of the spleen and envelopes the organ.
What is the Ligament of Treitz?
The ligament of Treitz is the non-striated muscle which is attached through connective tissues to the diaphragm, just adjacent to the oesophageal opening. The ligament of Treitz is made out of fibromuscular bands of the smooth muscle. It is very thin and therefore cannot be seen in the CT imaging. However, it lies at the spot where the jejunum begins.
What is the structure of the ligament of Treitz?
Structure of the Ligament of Treitz. The ligament of Treitz is created by a fold of the peritoneum that lies over the suspensory muscle in the duodenum. This muscle is also known as the musculus suspensorius duodenii. The ligament of Treitz has mainly two parts.
What is the Duodenojejunal junction?
The Duodenojejunal junction is supported by a thin muscle that serves as an attachment to the suspensory muscle of the duodenum. The angle of flexure increases as this suspensory muscle contracts, thereby enhancing the movement of the contents within the intestinal tract.
What ligament is used for gut rotation?
Often, it also helps in identifying the exact source of intestinal bleeding. The ligament of Treitz also has a role in the gut rotation as it offers the point of fixation. It also helps with the process of digestion, by creating a wide angle at the duodenojejunal flexure.
What is the layer of muscle that emerges from the respiratory diaphragm through its right esoph?
It is a layer of muscle that emerges from the respiratory diaphragm through its right esophageal crus. It also includes the ligamentous and the muscular fibers that emerge from the superior mesenteric artery and the celiac trunk. The muscle is voluntary in nature and is created by a tendon that has two muscular ends, each with a different function and embryological genesis. Therefore, the ligament of Treitz has quite an uncommon structure. The lower part of the muscle may be constant with the rounded as well as the longitudinal layer of muscle lying towards the duodenojejunal junction.
What is the superior portion of the ligament of Treitz?
The superior portion of the ligament of Treitz is also known as Hilfsmuskel. The above two parts are considered separately while discussing the anatomy and the suspensory muscle is used to imply only the lower structure that is attached to the ligament of Treitz.
Where is the Treitz ligament located?
The ligament of Treitz has mainly two parts. The first part of it passes through the right part of the crus of the diaphragm and goes over to join the connective tissue that surrounds the celiac artery. The second part of the ligament of Treitz emerges from the connective tissues in the duodenum, lying between the left renal vein and the pancreas.
