Coronary veins drain the heart and generally parallel the large surface arteries (see Figure 17.4. 1). The great cardiac vein can be seen initially on the surface of the heart following the interventricular sulcus, but it eventually flows along the coronary sulcus into the coronary sinus on the posterior surface.

Where does the coronary sulcus drain?
Functional Anatomy It empties the blood of the coronary veins right into the right atrium, proximal to the conjunction of the posterior interventricular sulcus and the coronary sulcus.
What is sulcus terminalis?
The terminal sulcus is a groove in the right atrium of the heart. The terminal sulcus marks the separation of the right atrial pectinate muscles from the sinus venarum. … On the internal aspect of the right atrium, corresponding to the terminal sulcus is the crista terminalis.
What vein runs along the AV groove?
The small cardiac vein runs along the right AV groove downward toward the crux, where it subsequently empties into the coronary sinus. Some of the anterior cardiac veins drain directly into the right atrium.Which large coronary vein runs through the coronary sulcus collects blood from most of the other coronary veins and empties the blood at right atrium?
The coronary sinus empties directly into the right atrium near the conjunction of the posterior interventricular sulcus and the coronary sulcus (crux cordis area), located between the inferior vena cava and tricuspid valve; this atrial ostium can be partially covered by a Thebesian valve, although the anatomy of this …
Which coronary artery is found in the anterior interventricular sulcus?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.
Article first time published onWhat is anterior interventricular groove?
The anterior interventricular sulcus (or anterior longitudinal sulcus) is one of two grooves that separates the ventricles of the heart, the other being the posterior interventricular sulcus. The anterior interventricular sulcus is situated on the sternocostal surface of the heart, close to its left margin.
Do all coronary veins drain into the coronary sinus?
Coronary sinusSourceGreat cardiac veinDrains toRight atriumIdentifiersLatinSinus coronarius
What drains into the right coronary artery?
The right coronary artery supplies blood to the right ventricle, the right atrium, and the SA (sinoatrial) and AV (atrioventricular) nodes, which regulate the heart rhythm. The right coronary artery divides into smaller branches, including the right posterior descending artery and the acute marginal artery.
Do all cardiac veins drain into the coronary sinus?
Venous Supply to the Heart. The great cardiac vein, the middle cardiac vein, and the small cardiac vein all drain into the coronary sinus (which opens into the right atrium).
Where is Vasa Vasorum located?
The vasa vasorum (VV) — “vessels on vessels” — are blood vessels located on the outside of arteries (Figure 1). Arteries are living tissue and, like all cells, require blood flow to acquire nutrients and dispose of waste.
What blood vessel is found in the anterior medial thigh?
Femoral arterySourceExternal iliac arteryBranchesSuperficial epigastric artery, superficial iliac circumflex, superficial external pudendal, deep external pudendal, deep femoral artery, continues as popliteal arteryVeinFemoral veinSuppliesAnterior compartment of thigh
What valve is located between the right atrium and right ventricle?
Open tricuspid and mitral valves Blood flows from the right atrium into the right ventricle through the open tricuspid valve, and from the left atrium into the left ventricle through the open mitral valve.
Which artery travels under the left auricle and then divides into two branches?
Left coronary artery – divides into two branches (the circumflex artery and the left anterior descending artery). Left anterior descending artery (LAD) – supplies blood to the front and bottom of the left ventricle and the front of the septum. Pulmonary veins – bring oxygen-rich blood back to the heart from the lungs.
Which artery runs along the sulcus and supplies blood to the right atrium and SA node?
right coronary artery travels along the coronary sulcus (between the right atrium and ventricle), where it typically gives off smaller branches to the right atrium, AV node (80% of people), and SA node (55% – 60% of people).
What is LAD LCX RCA?
RCA: Right coronary artery; LMCA: Left main coronary artery; LAD: Left anterior descending; LCX: Left circumflex artery.
What is a coronary sulcus?
The coronary sulcus is circumferential and separates the atria from the ventricles. The anterior and posterior interventricular sulci or grooves separate the ventricles.
What 3 vessels fill the right atrium?
The blood vessels include the superior and inferior vena cava. These bring blood from the body to the right atrium. Next is the pulmonary artery that carries blood from the right ventricle to the lungs.
What is the sulci of the heart?
Sulci of the Heart The coronary sulcus (or atrioventricular groove) runs transversely around the heart – it represents the wall dividing the atria from the ventricles. The sulcus contains important vasculature such as the right coronary artery. … They represent the wall separating the ventricles.
Which vein drains the posterior aspect of the ventricles of the heart quizlet?
Middle cardiac vein drains what area? Posterior portions of the right and left ventricles.
Which vein drains blood from small and great cardiac vein?
Drains fromSmall venules of the apex of heartDrains toCoronary sinusDrainage areaExternal layer of the myocardium of the ventricles and left atrium
Which vein drains the right anterior side?
Anterior cardiac veinsDrains toRight atriumIdentifiersLatinVenae cardiacae anteriores, venae ventriculi dextri anterioresTA98A12.3.01.012
Which vein travels with the circumflex artery?
The Anterior Great Cardiac Vein and the Circumflex artery (Cx): The great cardiac vein runs on the left side of the retro-pulmonary part of the LAD.
What two arteries run along the AV groove?
One, the atrioventricular groove, is along the line where the right atrium and the right ventricle meet; it contains a branch of the right coronary artery (the coronary arteries deliver blood to the heart muscle). The other, the anterior interventricular sulcus, runs along the line between the…
Which of the following veins runs adjacent to the anterior interventricular artery?
The great cardiac vein, the longest venous vessel of the heart, consists of the anterior interventricular vein and its continuation along the atrioventricular groove [4,7].
What runs with the posterior interventricular artery?
The great cardiac vein accompanies the anterior interventricular artery; the middle cardiac vein accompanies the posterior interventricular artery and the small cardiac vein accompanies the marginal artery.
What runs in posterior interventricular sulcus?
Base and diaphragmatic surface of heart. (Posterior interventricular sulcus visible at lower left, where the middle cardiac vein is labeled.) In it runs the posterior interventricular artery and middle cardiac vein. …
