The valves of the heart are attached to papillary muscles by `:-`

Options

A. Columnae camae
B. Chordae tendinae
C. Tendinae
D. Pectinati muscles

Answer

To solve the question regarding the attachment of heart valves to papillary muscles, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Heart Structure**:
- The heart consists of four chambers: the right atrium, left atrium, right ventricle, and left ventricle.
- Each ventricle has valves that regulate blood flow.

2. **Identifying the Valves**:
- The left side of the heart contains the mitral valve (between the left atrium and left ventricle).
- The right side has the tricuspid valve (between the right atrium and right ventricle).

3. **Role of Papillary Muscles**:
- Papillary muscles are located within the ventricles and play a crucial role in the function of the heart valves.
- They contract to prevent the inversion or prolapse of the valves during ventricular contraction.

4. **Connection Between Valves and Papillary Muscles**:
- The valves are connected to the papillary muscles through fibrous cords known as chordae tendineae.
- These chordae tendineae ensure that the valves close properly and do not allow backflow of blood.

5. **Conclusion**:
- Therefore, the valves of the heart are attached to the papillary muscles by **chordae tendineae**.

### Final Answer:
The valves of the heart are attached to the papillary muscles by **chordae tendineae**.
