Q

Is through the coronary sinus the only place the heart empty venous blood into the right atrium?

17
Q

The interior of the right ventricle is divided by two muscular ridges. Which?

A

The supraventricular crest and the septomarginal trabeculae

18

19
Q

How many cusps, or leaflets, does the right atrioventricular valve have?

A

Three - tricuspid

20
Q

What is the smooth walled part of the right outflow tract called?

A

A

Sternocostal surface

26
Q

From which surface does the posterior papillary muscles of the left ventricle arise?

A

Diaphragmatic surface

27
Q

How many cusps does the aortic valve have?

A

Three semilunar cusps

28
Q

On the outside of the heart you can find the anterior and posterior interventricular sulcus. What is the structure you can find inside the heart at these sites?

A

The interventricular septum.

29
Q

What is the name of the artery and vein that supply the pericardium?

A

Pericardiophrenic artery and vein.

Artery arises from the internal thoracic artery.
Vein empties into brachiocephalic vein.

Q

What nerve(s) innervate the pericardium?

A

Phrenic nerve, vagus nerve and sympathetic trunk

31
Q

What are the sites of reflection of the pericardium?

A

Reflection lines are sites where the visceral layer becomes parietal.

32
Q

What two sinuses can be found between the reflection lines?

A

Transverse sinus and oblique sinus

33
Q

The pericardium can be divided into an outer fibrous pericardium and an inner serous pericardium. Which two layers can the serous pericardium be divided into?

A

Visceral and parietal layer

34
Q

Which of the visceral and parietal layers lie closest to the heart?

A

The visceral layer (also called epicardium)
