Q7. Which statement best describes the course of the pericardiacophrenic artery?
- It ascends through the carotid sheath
- It passes through the vertebral canal
- It descends along the pericardium with the phrenic nerve
- It travels inside the esophagus
Q8. What is the proximal arterial pathway to the pericardiacophrenic artery?
