posterior interventricular sulcus

In the coronary circulation, the posterior interventricular artery (PIV, PIA, or PIVA), most often called the posterior descending artery (PDA), is an artery running in the posterior interventricular sulcus to the apex of the heart where it meets with the anterior interventricular artery or also known as Left Anterior

What is the function of the interventricular sulcus?

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.

What is located in the posterior coronary sulcus?

The coronary sinus is located in the posterior portion of the coronary sulcus on the diaphragmatic or posterior surface of the heart.

What structures are found in the interventricular sulcus?

The anterior interventricular branch of the left coronary artery runs in the sulcus along with the great cardiac vein.

What part of the heart does the posterior interventricular artery supply?

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 posterior interventricular artery?

The origin of the posterior interventricular artery accounts for the termed dominance of the heart. The main function of the posterior interventricular artery is to supply a small posterior aspect of the interventricular septum [7] and the posterior aspect of the right ventricle [6].

What does the 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 internal structure of the heart is marked by the anterior and posterior interventricular sulci?

Located between the left and right ventricles are two additional sulci that are not as deep as the coronary sulcus. The anterior interventricular sulcus is visible on the anterior surface of the heart, whereas the posterior interventricular sulcus is visible on the posterior surface of the heart.

Which vein runs in posterior interventricular groove?

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 happens when RCA is blocked?

When one or more of the coronary arteries suddenly becomes completely blocked, a heart attack (injury to the heart muscle) may occur. If the blockage occurs more slowly, the heart muscle may develop small collateral blood vessels (or detours) for other coronary arteries to reroute the blood flow, and angina occurs.

What is the function of the interventricular septum quizlet?

Interventricular septum is a muscular wall that separates right and left ventricles. It prevents the mixing of oxygenated and deoxygenated blood.

What is a sulcus in 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.
