What is the marginal artery a branch of?
The marginal artery of Drummond, also known as the marginal artery of the colon, is a continuous arterial circle or arcade along the inner border of the colon formed by the anastomoses of the terminal branches of the superior mesenteric artery (SMA) and inferior mesenteric artery (IMA).
Where does IMA branch?
The IMA branches off the anterior surface of the abdominal aorta below the renal artery branch points, 3-4 cm above the aortic bifurcation (into the common iliac arteries) at the L3 vertebral level. All these arterial branches further divide into arcades which then supply the colon at regular intervals.
What organs are supplied by the inferior mesenteric artery and its branches?
The inferior mesenteric artery, also a branch of the abdominal aorta, supplies the distal third of the transverse colon, the descending colon and sigmoid colon, and the superior portion of the rectum as the superior hemorrhoidal artery.
How many inferior mesenteric arteries are there?
There are usually around 3 branches of this artery, which pass inferiorly and obliquely posterior to the peritoneum, but anterior to psoas major, the kidneys and ureters. These branches supply the inferior part of the descending colon and the S-shaped sigmoid colon.
What is a marginal artery?
The marginal artery of Drummond (MA) is an anatomically variable blood vessel that forms a major anastomotic network between the superior and inferior mesenteric arteries. It vascularizes the transverse and descending colons and is a major contributor to the collateral circulation of left-colic structures.
What does the marginal artery branches off?
The marginal artery gives off vasa recta to the transverse colon, the splenic flexure, and the descending colon. The sigmoid colon is supplied by branches of the left colic artery, as well as by two to four sigmoidal arteries, which are branches of the inferior mesenteric artery.
Where does IMA come from?
The inferior mesenteric artery (IMA) is one of the three non-paired major splanchnic arteries, in the abdominal cavity, arising from the abdominal aorta and supplying the hindgut. It is the smallest of the three anterior visceral branches of the abdominal aorta.
Is IMA a government body?
Indian Medical Association (IMA) is the largest Medical Association of the world. IMA is a voluntary body constituted by doctors practicing modern system of medicine. It represents the collective consciousness of over 2.7 Lakh doctors in all the 686 districts of India organised in 30 state and 1765 Local Branches.
How do you find the IMA on ultrasound?
The IMA was located by scanning the aorta in cross section starting from the renal arteries and ending at the aortic bifurcation. The IMA was identified by its characteristic origin on the left ante– rior aspect of the aorta and its course descending along the left side of the aorta (Fig. 1A).
Is the IMA retroperitoneal?
It is a retroperitoneal structure situated behind the peritoneum. Fig 1.0 The origin of the IMA from the abdominal aorta.
What does the SMA supply?
Anatomical terminology In human anatomy, the superior mesenteric artery (SMA) arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.
What does the inferior mesenteric artery supply to?
The inferior mesenteric artery, the smallest of the mesenteric arteries, is an anterior branch of the abdominal aorta. It continues in the pelvis as the superior rectal artery. It supplies the distal transverse colon, splenic flexure, descending and sigmoid colon, and the upper part of the rectum.
What are the three mesenteric arteries?
The gastrointestinal tract is supplied by the celiac trunk, the superior mesenteric artery (SMA), and the inferior mesenteric artery (IMA) [13].
Where is celiac trunk?
The celiac trunk, also known as the celiac artery, is a short vessel that arises from the aorta and passes below the median arcuate ligament, just as the aorta enters the abdomen at the level of the T12 vertebra. The celiac trunk measures about 1.5cm to 2cm in length.
How many abdominal aorta branches are there?
The abdominal aorta runs from the diaphragm and ends just above the pelvis, where it divides into the iliac arteries. There are five arteries that branch from the abdominal aorta: the celiac artery, the superior mesenteric artery, the inferior mesenteric artery, the renal arteries and the iliac arteries.
What are the 4 main arteries of the heart?
The right coronary artery, the left main coronary, the left anterior descending, and the left circumflex artery, are the four major coronary arteries. Blockage of these arteries is a common cause of angina, heart disease, heart attacks and heart failure.
What are the branches of coronary artery?
The coronary arteries consist of two main arteries: the right and left coronary arteries, and their two branches, the circumflex artery and the left anterior descending artery.
Which coronary artery is the Widowmaker?
The widow-maker is a massive heart attack that occurs when the left anterior descending artery (LAD) is totally or almost completely blocked. The critical blockage in the artery stops, usually a blood clot, stops all the blood flow to the left side of the heart, causing the heart to stop beating normally.
What is the function of the marginal artery?
It supplies the majority of the myocardium of the right ventricle of the heart. Some authors refer to this artery as the acute marginal artery, or the right marginal branch of right coronary artery. The right marginal artery gives off several collateral branches to supply the adjacent surfaces of the right ventricle.
How many arteries in the heart can be bypassed?
The grafted artery or vein bypasses (that is, it goes around) the blocked portion of the coronary artery. This new passage routes oxygen-rich blood around the blockage to the heart muscle. As many as four major blocked coronary arteries can be bypassed during one surgery.
What does IMA mean?
IMA is actually a contraction of the slang phrase I’m gonna, which means I am going to. IMA is often used just to represent I Am (as in, IMA out of here), but is also used to represent the complete phrase I Am Going To, (as in, IMA get out of here). IMA is often typed as IMMA and sometimes as I’MA.

How do you find the IMA?
The IMA comes off the anterolateral aspect of the left side of the aorta. The takeoff is below the renal arteries and just above the bifurcation of the common iliac arteries, usually at L3.
Where does the IMV drain?
The inferior mesenteric vein (IMV) drains the descending colon, the sigmoid colon, and the rectum through the left colic vein, the sigmoid branches, and the superior rectal vein, respectively. The IMV joins the splenic vein, which then joins the SMV to form the portal vein.
Where is the left colic artery?
It runs to the left behind the peritoneum and in front of the psoas major muscle. After a short, but variable, course, it divides into an ascending and a descending branch. The stem of the artery or its branches cross the left ureter and left internal spermatic vessels.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
