What is the interventricular sulcus of the heart?
What is the interventricular sulcus of the heart?
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 are coronary sulcus and interventricular 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 does anterior interventricular sulcus contain?
The interventricular sulcus contains the left anterior descending coronary artery and the left coronary vein embedded within adipose tissue. The right ventricle lies to your left and toward the base relative to the anterior interventricular sulcus.
Is the interventricular septum the same as the interventricular sulcus?
The anterior interventricular sulcus is a groove located on the anterior part of the heart, while the posterior interventricular sulcus is located on the posterior part of the heart. These two landmarks form the margins of the interventricular septum.
What is the function of the posterior interventricular sulcus?
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.
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.
Where is the interventricular sulcus?
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.
How do the coronary arteries relate to 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).
Why is interventricular septum located in the heart of birds and mammals What is its function?
The interventricular septum is located in the heart of birds and mammals because they have 4-chambered heart, that is, 2 atria and 2 ventricles. This is where the separation of oxygenated and de-oxygenated blood takes place.
What is the function of the interventricular septum in the heart?
The interventricular septum divides the right and left ventricles, running in the plane of the anterior and posterior interventicular grooves.
What is the function of interventricular artery?
What part of the heart does the posterior interventricular artery serve?
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.
