Heart Quiz:

 

1. Which of these are the sets of cellular connections that regulate energy flow through the muscle cells of the heart?

Papillary muscles
Trabeculae carnae
Intercalated discs
Chordae tendineae

 

2. Which statement represents the purpose of the heart auricles?

The auricles protect the top of the heart.
The auricles add mass to balance the weight of the heart.
The auricles constrict the pressure in the atria of the heart.
The auricles prevent overfilling of the atria in the heart.

 

3. Which of these represents the location of the sheep’s heart’s apex?

The apex is inside the right atrium.
The apex is at the bottom of the heart.
The apex is at the top of the heart.
The apex is inside the left ventricle of the heart.

 

4. Which of these is a clue for distinguishing between the anterior and posterior sides of the sheep’s heart?

The left auricle is larger on the anterior side than on the posterior side of the sheep’s heart.
The interventricular sulcus appears as a “sash” from the (heart’s) upper left to lower right on the anterior side of the sheep’s heart.
The interventricular septum appears as a vertical line from the (heart’s) top center to bottom center on the anterior side of the sheep’s heart.
The left auricle is smaller on the anterior side than on the posterior side of the sheep’s heart.

 

5. Which of these represents the location of the base of the sheep’s heart?

The base is inside the right atrium.
The base is at the bottom of the heart.
The base is at the top of the heart.
The base is inside the left ventricle of the heart.

 

6. Which of these is a clue that will provide the location of the left auricle of the sheep’s heart?

The left auricle is larger on the anterior side than on the posterior side of the sheep’s heart.
The left auricle is associated with the interventricular sulcus at the base of heart on the anterior side of the sheep’s heart.
The left auricle is associated with the interventricular sulcus at the apex of heart on the posterior side of the sheep’s heart.
The left auricle is smaller on the anterior side than on the posterior side of the sheep’s heart.

 

7. Which of these is a clue to the location of the pulmonary trunk while examining the anterior external surface of the sheep’s heart?

The pulmonary trunk is the first vessel that is visible, starting from the upper left of the anterior side of the sheep’s heart.
The pulmonary trunk is the second vessel that is visible, starting from the upper right of the anterior side of the sheep’s heart.
The pulmonary trunk is the third vessel that is visible, starting from the upper right of the anterior side of the sheep’s heart.
The pulmonary trunk is the fourth vessel that is visible, starting from the upper right of the anterior side of the sheep’s heart.

 

8. Which of these is a clue to the location of the brachiocephalic artery while examining the anterior external surface of the sheep’s heart?

This particular artery is the first that is visible, starting from the upper left of the anterior side of the sheep’s heart.
This particular artery is the second that is visible, starting from the upper left of the anterior side of the sheep’s heart.
This particular artery is the third that is visible, starting from the upper left of the anterior side of the sheep’s heart.
This particular artery is the fourth that is visible, starting from the upper left of the anterior side of the sheep’s heart.

 

9. Which of these is a clue that provides the location of the right atrium inside the heart while examining only the outside of the sheep’s heart?

The position of the interventricular sulcus will allow you locate the external position of the right atrium.
The position of the right semilunar valve will allow you to locate the external position of the right atrium.
The position of the left semilunar valve will allow you to locate the external position of the right atrium.
The position of the right mitral valve will allow you to locate the external position of the right atrium.

 

10. Which of these valves is located between the upper and lower left heart chambers?

Mitral valve
Semilunar valve
Tricuspid valve
Stenotic valve

 

11. Which of these valves is located at the base of both the pulmonary trunk and the aorta?

Mitral valve
Semilunar valve
Tricuspid valve
Stenotic valve

 

12. Which of these valves is located between the upper and lower right heart chambers?

Mitral valve
Semilunar valve
Tricuspid valve
Stenotic valve

 

13. Which of these are the “heart strings”?

Rugae muscles
Trabeculae carnae
Intercalated discs
Chordae tendineae

 

14. Which of these would help you find the location of the pulmonary veins when examining the external sheep’s heart?

Locate the anterior interventricular sulcus and left auricle; look behind the auricle.
Locate the posterior interventricular sulcus and left auricle; look behind the auricle.
Locate the anterior interventricular sulcus and right auricle; look behind the auricle.
Locate the posterior interventricular sulcus and right auricle; look behind the auricle.

 

15. Which of these attach directly to the papillary muscles?

Rugae muscles
Trabeculae carnae
Intercalated discs
Chordae tendineae

 

NOTE: You are responsible for visual identification of the internal and external structures of the sheep’s heart, as indicated in your objectives. Practical applications such as these are an inherent part of each laboratory activity and exam.
