Pylangium in frog is located in :

Options

A. Conus arteriosus
B. Sinus venosus
C. Atrium
D. Ventricle

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the location of the pylangium in frogs. We need to identify where this structure is situated within the frog's circulatory system.

2. **Defining Pylangium**: Pylangium is described as a highly muscular portion of the arterial trunk that connects directly to the ventricle of the heart. This information is crucial for determining its location.

3. **Analyzing the Options**:
- **Option 1: Cornous Arteriosus**: This is the correct option. The pylangium is located in the Cornous Arteriosus, which is adjacent to the ventricle.
- **Option 2: Sinus Venosus**: This is incorrect. The sinus venosus is the first chamber of the heart that empties into the right atrium, not where the pylangium is located.
- **Option 3: Arterium**: This option is also incorrect. The arterium refers to the upper chamber of the heart, which does not contain the pylangium.
- **Option 4: Ventricle**: This option is incorrect as well. The ventricle is the lower chamber of the heart and does not house the pylangium.

4. **Conclusion**: Based on the analysis, the correct answer is that the pylangium is located in the Cornous Arteriosus.

**Final Answer**: The pylangium in a frog is located in the Cornous Arteriosus.
