The marginal artery runs in the mesentery close to the large intestine as part of the vascular arcade that connects the superior mesenteric artery and the inferior mesenteric artery. [1] It provides an effective anastomosis between these two arteries for the large intestine.
Marginal artery can refer to: Marginal artery of the colon, also known as the artery of Drummond; Right marginal branch of right coronary artery, a branch of the right coronary artery that follows the acute margin of the heart; Left marginal artery, a branch of the circumflex artery, traveling along the left margin of heart
The right marginal branch is the largest branch to split off from the right coronary artery. [1] [2] It often anastomoses with the nearby parallel posterior interventricular artery, which itself is usually a continuation of the right coronary artery. [3]
Ramus or intermediate artery; Right coronary artery. Right marginal artery; Posterior descending artery; The left coronary artery arises from the aorta within the left cusp of the aortic valve and feeds blood to the left side of the heart. It branches into two arteries, the left anterior descending and the left circumflex.
The RCA also supplies the SA nodal artery in 60% of people. The other 40% of the time, the SA nodal artery is supplied by the left circumflex artery. [citation needed] Although rare, several anomalous courses of the right coronary artery have been described including origin from the left aortic sinus. [9]
The middle colic artery is an artery of the abdomen; a branch of the superior mesenteric artery distributed to parts of the ascending and transverse colon.It usually divides into two terminal branches - a left one and a right one - which go on to form anastomoses with the left colic artery, and right colic artery (respectively), thus participating in the formation of the marginal artery of the ...
The IMA arises from the anterior aspect of the abdominal aorta. [2] [3]Its origin is situated at the L3 vertebral level, [2] [3] below the origins of the two renal arteries, [3] 3-4 cm above the aortic bifurcation, [3] [2] at the level of the umbilicus, and posterior to the inferior border of the horizontal (III) part of the duodenum.
In humans, many of these branches are named, but in smaller animals the branches are more variable. In some animals, including humans, branches of these arteries join with the marginal artery of the colon, which means that occlusion of one of the main arteries does not necessarily lead to the death of the part of the gut that it usually supplies.
