In frog, the surface of attachment of tongue is

Options

A. Palatine
B. Sphenoid
C. Pterygoid
D. Hyoid apparatus

Answer

To answer the question regarding the surface of attachment of the tongue in frogs, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Anatomy of the Frog's Tongue**:
- The frog's tongue is a specialized structure that plays a crucial role in feeding. It is important to identify where this tongue is anchored within the frog's anatomy.

2. **Identifying the Options**:
- The question provides four options: Palatine, Sphenoid, Pterygoid, and Hyoid Apparatus. We need to analyze each option to determine which one serves as the attachment point for the tongue.

3. **Analyzing Each Option**:
- **Palatine**: This bone connects the anterior side of the cranium with the middle of the maxilla, but it is not the primary attachment point for the tongue.
- **Sphenoid**: This bone forms the floor of the cranium, but it does not provide a direct attachment for the tongue.
- **Pterygoid**: This bone contributes to the posterior ventral margin of the orbit, but it is not involved in the attachment of the tongue.
- **Hyoid Apparatus**: This structure is located on the floor of the buccal cavity and provides a surface for the attachment of the tongue muscles and respiratory muscles.

4. **Conclusion**:
- Based on the analysis, the correct answer is the **Hyoid Apparatus**. It serves as the surface for the attachment of the tongue and plays a role in the ingestion of food and breathing.

### Final Answer:
In frogs, the surface of attachment of the tongue is the **Hyoid Apparatus**.
