What is the posterior interventricular sulcus?
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.
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.
Which posterior branch of the right coronary artery lies in the posterior interventricular sulcus?
It is typically a branch of the right coronary artery (70%, known as right dominance). Alternately, the PIV can be a branch of the circumflex coronary artery (10%, known as left dominance) which itself is a branch of the left coronary artery….

What is the 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. There are two grooves on the external surface of the heart.
What is the posterior interventricular artery?
A large coronary artery called the posterior interventricular artery, or posterior descending artery (PDA), runs lengthwise along the back of the heart, supplying blood to its posterior (bottom) portion. Like the other coronary arteries, the posterior descending artery can be affected by coronary artery disease.
What 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.
Where does the posterior interventricular artery supply blood to?
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 quizlet?
Anterior interventricular artery – also called the left anterior descending artery, supplies the anterior surface of both ventricles and most of the interventricular septum 2. Circumflex artery – supplies the left atrium and ventricle. -Shorter coronary artery that is hidden anteriorly by the pulmonary trunk.
What is the function of interventricular septum?
The interventricular septum divides the right and left ventricles, running in the plane of the anterior and posterior interventicular grooves.
Where is posterior interventricular artery?
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.
