The right and left coronary arteries arise from which of the great vessels?

The aorta just superior to the aortic valve

2

What is the location of the coronary arteries in relationship to the layers of the heart?

Subepicardial (between the epicardium and myocardium)

3

The right coronary artery gives off what branches?

1) Sinuatrial Nodal Artery
2) Right Marginal Artery
3) Posterior interventricular artery

4

What is the condition when a coronary artery dives into the myocardium?

Myocardial Brdges

5

Which of the coronary arteries is shorter?

Left

6

Which branch of the left coronary artery lies within the anterior interventricular sulcus?

Anterior Interventricular artery

7

Which branch of the left coronary artery will cross posterior to anastomose with the right coronary artery?

Circumflex Artery

8

Which artery will branch off of the cricumflex artery?

Left Marginal Artery

9

What does it mean when it is said that a coronary artery is dominant?

Which artery does the posterior interventricular artery branches from

10

In what percent of the population is the right coronary artery dominant?

70%

11

In right coronary dominance, what does the right coronary artery supply?

1) Right Atrium
2) Most of the right ventricle
3) Diaphragmatic surface of the left ventricle
4) Posterior 1/3 of the interventricular septum
5) Conduction system to the proximal parts of the right and left bundle branches

12

In right coronary artery dominance, the left coronary artery supplies what?

1) Left Atrium
2) Most of the left ventricle
3) Part of the Right Ventricle
4) Anterior 2/3 of the interventricular septum

13

What are typicllay considard to be the end arteries of the coronary arteries?

Branches of the coronary arteries

14

Where do anastomoses occur between which arteries?

1) Right Coronary and circumflex arteries

Directly into the right atrium

20

What are the smallest veins of the heart?

Venae Cordis Minimae

21

What is the location of the venae cordis minimae?

Within the walls of the heart and drain primarily into the right atrium

22

The great cardiac vein accompanies what other vessel as it drains the heart?

The anterior Interventricular Artery

23

The middle cardiac vein accompanies which other vessel as it drains the heart?

The Posterior Interventricular Artery

24

The small cardiac vein accompanies what arteries as it drains the heart?

The right coronary artery near the right lower margin of the heart

25

What is the general location of the posterior vein of the left ventricle?

To the left of the middle cardiac vein

26

What is the lymphatic drainage of the heart?

Subepicardial Lymphatic Plexus to the Tracheobronchial Node
