Which artery supplies the anterior wall of the heart and runs in the anterior interventricular sulcus?

• A. Left Pulmonary Artery
• B. Left Common Carotid Artery
• C. Anterior Interventricular Artery
• D. Great Cardiac Vein

Answer: (C)

The vessel responsible for supplying the anterior wall of the heart and traveling in the anterior interventricular sulcus is the anterior interventricular artery, also known as the left anterior descending artery. This artery runs down the front of the heart in that sulcus, heading toward the apex, and provides branches to the anterior wall of the left ventricle, the anterior portion of the interventricular septum, and the anterior papillary muscle. It typically originates from the left coronary artery.

Other options don’t fit because they are not coronary arteries: the left pulmonary artery is part of the pulmonary circulation to the lungs; the left common carotid artery supplies the head and neck; and the great cardiac vein is a vein that drains blood from the heart rather than supplying it.
