What is the function of interventricular groove?
role in cardiovascular system 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 anterior interventricular groove?
The anterior interventricular sulcus (or anterior longitudinal sulcus) is one of two grooves that separates the ventricles of the heart, the other being the posterior interventricular sulcus. The anterior interventricular sulcus is situated on the sternocostal surface of the heart, close to its left margin.
Is interventricular groove is coronary sulcus?
There are anterior and posterior interventricular sulci or grooves and a coronary sulcus (atrioventricular groove). The coronary sulcus is circumferential and separates the atria from the ventricles. The anterior and posterior interventricular sulci or grooves separate the ventricles.
What is the Paraconal interventricular groove?
The paraconal interventricular branch was a strong vessel which was branched from the left coronary artery. First, it ran towards the paraconal interventricular groove as the descending part, and next proceed to the atrial surface of the heart as the ascending part (Figs. 1 and 2).
What is groove of the heart?
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 does the interventricular groove contains?
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. The heart has five surfaces, anterior, posterior, inferior, and a right and left.
What coronary vein lies in the anterior interventricular sulcus?
great cardiac vein
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.
Is the anterior interventricular sulcus on the surface of the heart?
The ventricles of the heart are separated by two grooves, one of which, the anterior longitudinal sulcus (or anterior interventricular sulcus), is situated on the sternocostal surface of the heart, close to its left margin.
What lies in the atrioventricular groove?
The atrioventricular groove contains the coronary sinus, which is the largest vein of the heart and lies posteriorly opening into the right atrium. The interatrial groove is covered anteriorly by the ascending aorta and the main pulmonary artery.
What do you mean by groove?
1 : a long narrow channel or depression. 2a : a fixed routine : rut. b : a situation suited to one’s abilities or interests : niche. 3 : top form a great talker when he is in the groove.
