Chordae tendinae in the heart are found in

Options

A. Ventricle
B. Left auricle
C. Right auricle
D. S A Node

Answer

### Step-by-Step Solution:

1. **Understanding Chordae Tendineae**: The chordae tendineae are fibrous cords that connect the papillary muscles to the tricuspid and mitral valves in the heart. They play a crucial role in preventing the valves from inverting during ventricular contraction.

2. **Identifying the Location**: Chordae tendineae are specifically found in the ventricles of the heart. They are associated with the valves that separate the atria from the ventricles.

3. **Analyzing the Options**:
- **Option 1: Ventricle**: This is the correct answer because chordae tendineae are indeed located in the ventricles, connecting to the mitral and tricuspid valves.
- **Option 2: Left Auricle**: This option is incorrect. The left auricle is part of the atrium and does not contain chordae tendineae.
- **Option 3: Right Auricle**: This option is also incorrect. The right auricle is part of the atrium and does not have chordae tendineae.
- **Option 4: SA Node**: This option is incorrect as well. The SA node is the natural pacemaker of the heart, located in the right atrium, and does not contain chordae tendineae.

4. **Conclusion**: Based on the analysis, the correct answer is **Option 1: Ventricle**.
