Is the coronary sinus the great cardiac vein?

Is the coronary sinus the great cardiac vein?

The coronary sinus is the major venous tributary of the greater cardiac venous system; it is responsible for draining most of the deoxygenated blood leaving the myocardium.

Where are the coronary sinus and the great cardiac vein located?

The coronary sinus is formed by several smaller veins that feed into it. It is located in the posterior (back) surface of the heart, in the groove between the left atrium and left ventricle. The coronary veins that feed the coronary sinus are located in the thick layer of muscle in the heart, called the myocardium.

What is the difference between cardiac veins and cardiac sinus?

The coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the heart muscle (myocardium)….

Coronary sinus
Source Great cardiac vein
Drains to Right atrium
Latin Sinus coronarius

What veins drain into coronary sinus?

The coronary sinus receives drainage from most epicardial ventricular veins, including the oblique vein of the left atrium (and other left and right atrial veins), the great cardiac vein, the posterior vein of the left ventricle, the left marginal vein, and the posterior interventricular vein.

What is a cardiac sinus?

The coronary sinus is a collection of smaller veins that merge together to form the sinus (or large vessel), which is located along the heart’s posterior (rear) surface between the left ventricle and left atrium.

What is the difference between coronary sulcus and coronary sinus?

The structure contains the trunks of the nutrient vessels of the heart, and is deficient in front, where it is crossed by the root of the pulmonary trunk. On the posterior surface of the heart, the coronary sulcus contains the coronary sinus….

Coronary sulcus
Latin sulcus coronarius
TA98 A12.1.00.011
TA2 3945
FMA 7174

What is the function of the coronary sinus and where is it located?

The coronary sinus collects the majority of the cardiac venous blood. It receives the blood from the myocardium, a thick layer of muscle within the heart, and facilitates the movement of the blood into the right atrium. The coronary sinus often serves as a landmark for surgeons who are performing cardiac surgery.

What is the cardiac sinus?

What does the great cardiac vein drain into?

Gross anatomy Blood in each vessel flows in the same direction at this site. The great cardiac vein then drains into the left end (origin) of the coronary sinus, at the same end as the oblique vein of Marshall which together marks the origin of the coronary sinus.

Is the coronary sinus located in the coronary sulcus?

The coronary sinus, the length of which varies from 15 to 65 mm, is found at the posterior part of the coronary sulcus on the diaphragmatic or posterior surface of the heart and is the principal collector of the venous blood of the heart.
