Intermediate Great Cardiac Vein Quiz

Q1. Which sequence correctly describes the course of the great cardiac vein?

• Coronary sinus, anterior interventricular sulcus, apex, pulmonary trunk
• Right atrium, posterior interventricular sulcus, apex, coronary sinus
• Apex, anterior interventricular sulcus, coronary sulcus, coronary sinus
• Apex, posterior interventricular sulcus, superior vena cava, right atrium

Q2. Which arterial branch is the principal companion of the great cardiac vein during its ascent toward the coronary sulcus?

• Right coronary artery
• Anterior interventricular artery
• Right marginal artery
• Posterior interventricular artery

Q3. The great cardiac vein is most closely associated with which coronary artery branch after it turns into the atrioventricular groove?

• Posterior interventricular artery
• Circumflex artery
• Sinoatrial nodal artery
• Right marginal artery

Q4. The great cardiac vein primarily drains regions supplied by branches of which coronary artery?

• Right coronary artery exclusively
• Pulmonary artery
• Internal thoracic artery
• Left coronary artery

Q5. Which region is drained in part by tributaries of the great cardiac vein?

• Anterior ventricular myocardium
• Abdominal wall
• Lung parenchyma
• Diaphragmatic pleura only

Q6. Which vein is the venous companion of the posterior interventricular artery rather than the anterior interventricular artery?

• Middle cardiac vein
• Great cardiac vein
• Anterior cardiac vein
• Oblique vein of the left atrium

Q7. Which feature distinguishes the great cardiac vein from the anterior cardiac veins?

• It drains directly into the left atrium
• It carries oxygenated blood
• It lies entirely inside the interventricular septum
• It drains into the coronary sinus rather than directly into the right atrium

Q8. On which general surface of the heart does the great cardiac vein begin its most recognizable course?

• Interior of the right atrium
• Interior of the pulmonary trunk
• Posterior surface only
• Anterior surface

Q9. At approximately which landmark does the great cardiac vein change from an interventricular course to an atrioventricular course?

• Fossa ovalis
• Opening of the inferior vena cava
• Pulmonary valve
• Junction of the anterior interventricular and coronary sulci

Q10. Which statement correctly relates the great cardiac vein to the coronary sinus?

• It drains the coronary sinus into the left ventricle
• It becomes continuous with the coronary sinus
• It begins at the opening of the coronary sinus in the right atrium
• It has no anatomical relationship with the coronary sinus
