What artery lies in the coronary sulcus?
What artery lies in the coronary sulcus?
Arteries of the Heart
|coronary, right||ascending aorta||right coronary a. usually provides the posterior interventricular a.; it courses within the coronary sulcus|
What lies in the anterior interventricular sulcus?
The interventricular sulcus contains the left anterior descending coronary artery and the left coronary vein embedded within adipose tissue. The left ventricle lies to the right of the anterior interventricular sulcus and extends to and includes the apex of the heart.
What is the anterior branch of the left coronary artery?
left anterior descending artery
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. This artery supplies blood to the outer side and back of the heart.
What lies in the atrioventricular sulcus?
One, the atrioventricular groove, is along the line where the right atrium and the right ventricle meet; it contains a branch of the right coronary artery (the coronary arteries deliver blood to the heart muscle). The other, the anterior interventricular sulcus, runs along the line between the…
Where is coronary sulcus located?
The coronary sulcus, separating the atria and ventricles, spans from the upper medial end of the third left costal cartilage to the middle of the right sixth chondrosternal joint.
Which branch of the left coronary artery lies in the anterior interventricular sulcus?
The anterior interventricular sulcus is situated on the sternocostal surface of the heart, close to its left margin. The anterior interventricular branch of the left coronary artery runs in the sulcus along with the great cardiac vein….

What is the function of anterior interventricular artery?
Function. The artery supplies the anterolateral myocardium, apex, and interventricular septum. The LAD typically supplies 45-55% of the left ventricle (LV) and is therefore considered the most critical vessel in terms of myocardial blood supply.
Is another name for the coronary sulcus?
The coronary sulcus (also called coronary groove, auriculoventricular groove, atrioventricular groove, AV groove) is a groove on the surface of the heart that separates the atria from the ventricles.
What is the function of the coronary sulcus?
The superficial branch follows the groove (coronary sulcus) between the right ventricle and atrium and supplies the cardiac muscle of both chambers. The larger deep branch supplies the ventral wall of the right ventricle, the dorsal walls of both atria, and the muscular right atrioventricular valve.
What are the branches of right coronary artery?
Right coronary artery
- Anterior branches. Conal branch. Sinuatrial nodal branch. Anterior atrial branches.
- Marginal branches. Right marginal (acute) artery. Lateral atrial branches.
- Inferior branches. Atrioventricular branches. Inferior (posterior) interventricular branch. Interventricular septal branches.
What is the largest branch of the right coronary artery?
posterior descending artery
The inferior interventricular (descending) branch (also commonly referred to as the posterior descending artery (PDA)) is the largest of these branches, and descends in the inferior interventricular groove. On its course, it supplies the interventricular septum and adjacent surfaces of both ventricles.
Which coronary artery lies in the left atrioventricular sulcus?
The circumflex artery, also referred to as the left circumflex artery, stems from the left main and courses along the left atrioventricular groove. The circumflex artery gives rise to small arterial branches that supply the aortic root and myocardium near the antrioventricular groove.
What coronary vein lies in the anterior interventricular sulcus?
The great cardiac vein (GCV) runs in the anterior interventricular groove and drains the anterior aspect of the heart where it is the venous complement of the left anterior descending artery. It is the main tributary of the coronary sinus.
What is the name of the artery that runs down the anterior interventricular sulcus and is a branch of the left coronary artery?
In general, the LAD artery and its branches supply most of the interventricular septum; the anterior, lateral, and apical wall of the left ventricle, most of the right and left bundle branches, and the anterior papillary muscle of the bicuspid valve (left ventricle).
Is sulcus the same as groove?
is that groove is a long, narrow channel or depression; eg, such a slot cut into a hard material to provide a location for an engineering component, a tyre groove, or a geological channel or depression while sulcus is (anatomy) a furrow or groove in an organ or a tissue.
What is the function of the anterior interventricular sulcus?
Shallow grooves called the interventricular sulci, containing blood vessels, mark the separation between ventricles on the front and back surfaces of the heart. Function: This cardiac vein returns deoxygenated blood (metabolic waste products) from the anterior surfaces of the left ventricle.
Which coronary artery is most commonly blocked?
Coronary artery occlusion is most common in the left anterior descending artery (LAD, also known as the left anterior interventricular artery), but it may also occur in the right coronary arteries.
Can the left main artery be stented?
However some patients with advanced coronary artery disease are candidates for a procedure called left main stenting. This procedure involves placing a metal stent coated with a time-release medication into the artery to open the blockage.
