Coronary Sulcus[edit]
The coronary sulcus, also known as the atrioventricular groove, is a significant anatomical feature of the heart. It is a groove that encircles the heart, marking the division between the atria and the ventricles. This sulcus is an important landmark in the study of cardiac anatomy and is involved in the passage of major blood vessels that supply the heart.
Anatomy[edit]
The coronary sulcus is located on the external surface of the heart. It runs obliquely around the heart, separating the right atrium and right ventricle on the anterior surface, and the left atrium and left ventricle on the posterior surface. The sulcus is more pronounced on the posterior aspect of the heart.
Contents[edit]
The coronary sulcus contains important structures, including:
- The right coronary artery, which travels within the sulcus on the right side of the heart.
- The circumflex artery, a branch of the left coronary artery, which runs in the sulcus on the left side.
- The coronary sinus, a large venous channel that collects blood from the heart muscle and drains into the right atrium.
Function[edit]
The primary function of the coronary sulcus is to house and protect the coronary arteries and veins that supply blood to and from the heart muscle. These vessels are crucial for maintaining the myocardium's oxygen and nutrient supply, which is essential for the heart's continuous pumping action.
Clinical Significance[edit]
The coronary sulcus is a key landmark in various medical procedures and diagnostic techniques. It is often used as a reference point in echocardiography and during coronary artery bypass grafting (CABG) surgery. Understanding its location and contents is vital for cardiologists and cardiac surgeons.
