What coronary artery branches into the circumflex and the anterior interventricular artery?
What coronary artery branches into the circumflex and the anterior interventricular artery?
What coronary artery branches into the circumflex and the anterior interventricular artery?
The left coronary artery (LCA) extends along the coronary sulcus and supplies the left portion of the heart. It further branches into the circumflex artery and the anterior interventricular artery (left anterior descending artery).
What are the two major branches of the left coronary artery?
The left coronary artery continues into the superior aspect of the anterior interventricular groove where it bifurcates into its two terminal branches; the left anterior descending artery (anterior interventricular artery) and the circumflex artery.
What are the branches of left anterior descending artery?
| Left anterior descending artery | |
|---|---|
| Branches | septals, diagonals |
| Supplies | anterolateral myocardium, apex, interventricular septum, 45-55% of the left ventricle (LV) |
| Identifiers | |
| Latin | ramus interventricularis anterior arteriae coronariae sinistrae |
Where do the branches of the circumflex artery originate?
The atrial and anterior ventricular branches arise at the proximal segment of the circumflex artery and supply the sternocostal (anterior) surface of the left atrium and ventricle. The left marginal branch originates perpendicularly from the left coronary, around the left cardiac margin.
Which is part of the heart supply the left ventricles?
Left anterior ascending and descending arteries b. Left anterior descending and circumflex arteries d. Right coronary and left posterior descending arteries 5. The right atrium, right ventricles, and part of the left ventricle are supplied by the: a. Circumflex artery b. Left anterior descending artery d. Right coronary artery 6.
Where does the left marginal branch of the circumflex originate?
The left marginal branch originates perpendicularly from the left coronary, around the left cardiac margin. It descends down the rounded left cardiac margin towards the apex of the heart. When the marginal branch is larger in diameter, it supplies the lateral aspect of the left ventricle, all the way to the apex.
Which is the left branch of the circumflex artery?
From Wikipedia, the free encyclopedia “Circumflex branch” redirects here. For the circumflex branch of the posterior tibial artery, see Circumflex fibular artery. The ” LCX “, or left circumflex artery (or circumflex artery, or circumflex branch of the left coronary artery) is an artery of the heart.
Where does the left anterior descending artery supply blood to?
The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the left side of the heart. The circumflex artery branches off the left coronary artery and encircles the heart muscle.
Where are the main arteries of the heart located?
The rest of the right coronary artery and its main branch, the posterior descending artery, together with the branches of the circumflex artery, run across the surface of the heart’s underside, supplying the bottom portion of the left ventricle and back of the septum.
Where does the lateral circumflex femoral artery wrap around the neck?
The branch then pierces vastus lateralis and wraps around the neck of femur, where it contributes to the formation of the cruciate anastomosis. It is an anastomosis between the transverse branch of the lateral circumflex femoral, transverse branch of the medial circumflex, inferior gluteal and first perforating arteries.
