16. Right Ventricle

Question 1

Identify 1 -> 4

Answer 1

1. Right atrioventricular (tricuspid) valve (Anterior, Septal, and Posterior cusps)
2. Chordae tendineae
3. Superoposterior (anterior) papillary muscle
4. Apical trabeculations (trabeculae carneae)

Question 2

Identify 5

Answer 2

5. Septomarginal trabecula (Septal limb and Moderator band)

Question 3

Identify 6 -> 8

Answer 3

6. Interventricular septum (muscular part)
7. Conus arteriosus
8. Pulmonary valve (Anterior, Right, and Left semilunar cusps)

Question 4

The role of Chordae tendineae?

Answer 4

Chordae tendineae connect papillary muscles to the cusps of the tricuspid, or right atrioventricular, valve.
-> prevent the valve cusps from everting into the right atrium during contraction

Question 5

The ___ of the trabeculae carneae connects the interventricular septum to the base of the anterior papillary muscle.

Answer 5

septomarginal trabecula (moderator band)

Question 6

The role of septomarginal trabecula (moderator band)?

Answer 6

The septomarginal trabecula (moderator band) of the trabeculae carneae connects the interventricular septum to the base of the anterior papillary muscle.

Question 7

The septomarginal trabecula (moderator band) of the trabeculae carneae connects the interventricular septum to the base of the anterior papillary muscle.

→ This band of muscle conveys a portion of (1)____ bundle branch conduction system to the (2)__

Answer 7

1. the atrioventricular right
2. anterior papillary muscle.
