The interventricular sulcus is a superficial groove or depression between the ventricles. It is of importance because this is where some of the large coronary arteries and veins run. Those vessels carry blood to and from the walls of the heart.
What does the posterior interventricular sulcus do?
This artery runs in the posterior (inferior) interventricular sulcus. Its main function is to supply the diaphragmatic (inferior) surface of the myocardium and interventricular sulcus of the heart. The posterior interventricular artery can arise from either the left or right coronary artery.
Where is the anterior interventricular sulcus located on 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 is posterior interventricular?
The posterior interventricular artery (in 90% of individuals), which supplies the posterior one-third of the interventricular septum, the inferior surface of the right ventricle and a portion of the inferior surface of the left ventricle.
What is the function of the anterior interventricular artery?
It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system. Hence, blockage of this artery due to coronary artery disease can lead to impairment or death (infarction) of the conducting system.
What does anterior interventricular sulcus contain?
The other, the anterior interventricular sulcus, runs along the line between the right and left ventricles and contains a branch of the left coronary artery.
What does the interventricular sulcus separate?
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.
What is the function of the interventricular septum quizlet?
lies on the posterior interventricular sulcus, supplying oxygenated blood to both ventricles. Principle vein of the coronary circulation, draining the left anterior portion of the heart.
Where is the anterior interventricular artery?
The anterior interventricular artery, often clinically termed the left anterior descending artery, is a branch of the left coronary artery. It originates at the left margin of the pulmonary trunk, anterior to the left atrial auricle.
Where is the atrioventricular sulcus located?
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).
Is the posterior interventricular sulcus on the surface of the heart?
The ventricles are separated by two grooves, one of which, the anterior longitudinal sulcus, is situated on the sternocostal surface of the heart, close to its left margin, the other posterior longitudinal sulcus (posterior interventricular sulcus, inferior interventricular groove), on the diaphragmatic surface near
