Intermediate Small Cardiac Vein Quiz

Q1. Which sequence best describes the typical course of the small cardiac vein?

• Anterior interventricular sulcus, apex, left atrium
• Left coronary sulcus, aortic root, right ventricle
• Right margin, coronary sulcus, coronary sinus
• Posterior interventricular sulcus, pulmonary trunk, superior vena cava

Q2. Which two arterial relationships characterize the typical course of the small cardiac vein?

• Anterior interventricular artery and circumflex artery
• Pulmonary artery and ascending aorta
• Right marginal artery and right coronary artery
• Posterior interventricular artery and left marginal artery

Q3. Which myocardial territories contribute to the small cardiac vein?

• Left ventricular myocardium exclusively
• Pulmonary parenchyma
• Interventricular septum exclusively
• Right atrial and right ventricular myocardium

Q4. Which feature distinguishes the small cardiac vein from the great cardiac vein?

• It normally empties into the left ventricle
• It carries oxygenated rather than deoxygenated blood
• It follows the right margin and right coronary sulcus rather than the anterior interventricular sulcus
• It is an artery rather than a vein

Q5. Which feature distinguishes the small cardiac vein from the middle cardiac vein?

• The small cardiac vein is located entirely within the interventricular septum
• The middle cardiac vein drains into the pulmonary trunk
• The small cardiac vein contains arterial blood
• The small cardiac vein follows the right coronary sulcus rather than the posterior interventricular sulcus

Q6. Which statement about the small cardiac vein is anatomically important when identifying it in a specimen?

• It travels through the interatrial septum
• It always accompanies the anterior interventricular artery
• It passes through the aortic valve
• Its course is closely related to branches of the right coronary artery

Q7. Which statement about the presence of the small cardiac vein is correct?

• It is absent from all normal hearts
• It is present only in left-dominant hearts
• It is invariably the largest cardiac vein
• It may be small or absent in some individuals

Q8. If the small cardiac vein is poorly developed or absent, which veins can still drain portions of the anterior right ventricle directly into the right atrium?

• Bronchial veins
• Anterior cardiac veins
• Superior phrenic veins
• Pulmonary veins

Q9. How does the usual termination of the small cardiac vein differ from that of the anterior cardiac veins?

• The small cardiac vein usually joins the coronary sinus, while anterior cardiac veins drain directly into the right atrium
• Both are arterial vessels
• Both normally terminate in the pulmonary veins
• The small cardiac vein drains into the left atrium, while anterior cardiac veins drain into the coronary sinus

Q10. Which statement correctly describes the small cardiac vein in relation to the coronary sinus?

• It has no connection with the coronary venous system
• It forms the left end of the coronary sinus with the great cardiac vein
• It usually joins the coronary sinus near its right end
• It drains the coronary sinus into the superior vena cava
