Cardiac Veins and Their Functions

The video tutorial focuses on the cardiac veins, particularly the greater system. It begins with an overview of the cardiac veins, then delves into the great cardiac vein, its path, and its relationship with the anterior interventricular branch. The coronary sinus and middle cardiac vein are explored, followed by a discussion on the small and anterior cardiac veins. The tutorial concludes with a summary of the veins discussed and offers dissection tips to preserve the anterior cardiac veins.

What is the primary focus of the video on cardiac veins?

• The febsion veins

• The greater system

• The coronary arteries

• The pulmonary veins

Where is the great cardiac vein typically located in relation to the anterior interventricular branch?

• Not related

• At the same level

• Deeper

• More superficial

Which surface of the heart is associated with the coronary sulcus?

• Apex

• Anterior surface

• Diaphragmatic surface

• Lateral surface

What is the function of the coronary sinus?

• To connect the left and right ventricles

• To drain blood into the left atrium

• To collect blood from the greater system

• To supply oxygenated blood to the heart

What is the relationship between the great cardiac vein and the coronary sinus?

• The great cardiac vein supplies the coronary sinus

• They are not related

• The great cardiac vein drains into the coronary sinus

• The coronary sinus drains into the great cardiac vein

Which vein is associated with the right marginal branch?

• Great cardiac vein

• Small cardiac vein

• Anterior cardiac vein

• Middle cardiac vein

How do anterior cardiac veins differ from most greater system veins?

• They do not drain blood

• They drain into the left atrium

• They independently enter the right atrium

• They drain into the coronary sinus

What is the primary role of cardiac veins?

• To regulate heart rate

• To pump blood into the ventricles

• To drain the myocardium of blood

• To supply oxygen to the heart

How many anterior cardiac veins are typically found?

• Six to eight

• Nine to ten

• One to two

• Three to five

What is the recommended direction for dissecting the epicardium to preserve anterior cardiac veins?

• Towards the apex

• Away from the coronary sulcus

• In the direction of vasculature

• Towards the left atrium
