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

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

Answer: (C)

The main concept is the coronary artery that travels in the anterior interventricular sulcus to supply the front of the heart. The artery that sits in that groove and provides arterial blood to the anterior wall of the heart (the left ventricle) is known as the anterior interventricular artery, also called the left anterior descending (LAD) artery. It runs along the front surface in that sulcus and gives branches to the anterior wall and the interventricular septum.

Other options don’t fit: the left pulmonary artery is part of the pulmonary circulation and doesn’t run in that sulcus. The left common carotid artery supplies the head and neck, not the heart. The great cardiac vein travels in the same groove but is a vein, not an artery, draining blood from the heart back toward the coronary sinus.
