Posterior interventricular sulcus

Question 18

Where does the right coronary artery go?

Answer 18

Right aortic sinus, passes between right auricle and pulmonary trunk, then descends in coronary sulcus between right atrium and ventricle.

Question 19

Where is the atrial branch of the right coronary artery?

Answer 19

The groove between the right auricle and ascending aorta

Question 20

Where does the sinoatrial nodal branch of the right coronary artery go?

Answer 20

Passes posteriorly around superior vena cava to supply sinoatrial node

Question 21

Where is the atrioventricular nodal artery?

Answer 21

Distal end of right coronary artery as it forms the posterior interventricular artery. Supplies AV node.

Question 22

Answer 24

Originates from left sinus and enters left aspect of coronary sulcus. Quickly divides.

Question 25

Where does the anterior interventricular artery go?

Answer 25

Descends in anterior interventricular sulcus and supplies the anterior left ventricular wall, the anterior 2/3s of the interventricular septum, and the Bundle of His.

Question 26

Where does the circumflex artery go?

Answer 26

Courses around left border of the heart.

Question 27

Where does the Great Cardiac vein go?

Answer 27

Begins at apex, ascends in anterior interventricular sulcus. When it reaches the coronary sulcus, it banks left and continues onto the base of the heart.

Question 28

Where does the middle cardiac vein go?

Answer 28

Begins near apex, ascends in posterior interventricular sulcus.

Question 29

Where does the small cardiac vein go?

Answer 29

Begins in lower anterior section of coronary sulcus between the right atrium and ventricle, enters the coronary sinus at the atrial end.

Answer 31

Middle cardiac vein

Question 32

What does the great cardiac vein travel with?

Answer 32

First the anterior interventricular artery, then the circumflex artery.

Question 33

What travels with the small cardiac vein?

Answer 33

The right coronary artery

Question 34

What travels with the middle cardiac vein?

Answer 34

Posterior interventricular artery

Question 35

Where's the transverse sinus?

Answer 35

Behind the pulmonary trunk and the aorta
