What are interventricular grooves?

The interventricular grooves of the heart are surface depressions on the myocardium which indicate the deeper divisions of the ventricular chambers within the heart due to the interventricular septum.

What runs in the interventricular groove?

The interventricular groove runs anteriorly toward the apex and contains the great cardiac vein. Posteriorly, it continues along the inferior surface of the heart toward the right margin and contains the middle cardiac vein.

What structures are found in the interventricular septum?

The interventricular septum, also known as the ventricular septum, refers to the triangular wall of cardiac tissue that separates the left and right ventricles (i.e., the lower chambers) of the heart. The entire interventricular septum can be further divided into two parts: a muscular portion and a membranous portion.

What are the cardiac grooves?

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.

Where is the interventricular groove located?

interventricular grooves are surface depressions on the myocardium which lie over the interventricular groove. The ante- rior interventricular groove descends on the anterior surface of the heart between the left and right ventricles to the apex. It is near, and almost parallel to, the obtuse heart border (Fig. 1a).

Which artery is in anterior interventricular groove?

the left coronary artery
The left anterior descending artery, preferably known as the anterior interventricular artery (AIV), is the continuing branch of the left coronary artery. It is located subepicardially within the anterior and inferior interventricular sulci of the heart.

Which vein runs in posterior interventricular groove?

Middle cardiac vein
The middle cardiac vein, also known as the posterior interventricular vein, is a vessel located on the posterior aspect of the heart. It arises at the cardiac apex and runs within the posterior interventricular groove. It ends by draining into the right atrium via the coronary sinus.

What surface groove separates the right and left ventricles?

Shallow grooves called the interventricular sulci, containing blood vessels, mark the separation between ventricles on the front and back surfaces of the heart. There are two grooves on the external surface of the heart.

What is the posterior groove between the ventricles called?

The posterior interventricular sulcus or posterior longitudinal sulcus is one of the two grooves that separates the ventricles of the heart and is on the diaphragmatic surface of the heart near the right margin.

Where is the AV groove?

role in cardiovascular system. 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).

What is the largest artery in the heart?

The aorta is a large, cane-shaped vessel that delivers oxygen-rich blood to your body. It starts in the lower-left part of the heart and passes through the chest and abdomen.
