The marginal artery, also known as the marginal artery of Drummond, is called so because it forms a continuous arterial connection along the inner border of the colon, providing marginal blood supply. It is created by anastomoses between the terminal branches of the superior mesenteric artery and the inferior mesenteric artery. This "marginal" position allows it to serve as a crucial collateral route for blood flow, especially during situations where primary vessels may be compromised. Its name reflects its anatomical location along the margin of the colon.
What else can I help you with?
Why is the marginal artery called that?
It is called the marginal artery because it passes around the lateral margin (or side) of the heart.
What vein or artery is called OM?
obtuse marginal artery
Which artery parallels the mesocolic border of the colon are called?
marginal artery
What branch is the left marginal artery from?
the left marginal artery is a branch of the circumflex artery originating from the posterior interventricular sulcus and traveling at a left margin of the heart towards the apex.
When arteries and veins are not in the correct anatomic position what is that called and under what category are the corrective procedures located?
Obtuse marginal artery
What is the consequence when the marginal artery is block?
The marginal artery, also known as the marginal artery of Drummond, supplies blood to the colon. If this artery becomes blocked, it can lead to ischemia, causing reduced blood flow to the affected segment of the colon. This condition may result in symptoms such as abdominal pain, ischemic colitis, and, in severe cases, tissue necrosis or perforation, which can be life-threatening if not addressed promptly.
What vein runs with right marginal artery?
The small cardiac veins
What blood vessel gives rise to the marginal artery and posterior interventricular artery?
They branch off from the right coronary artery which arises from the aorta.
What are the marginal branch and posterior interventricular branch branches of?
right coronary artery
Coronary artery disease in the marginal arteries affect which part of the myocardium?
The penis
Which cardiac vein travels with the right marginal artery?
small cardiac vein.
What is a muscular branch of a coronary artery?
It is the same branch as the marginal branch. It is sometimes given a different name. e.i marginal branch of right coronary artery = muscular branch Least so say my anatomy teacher.
