The tongue of Frog is

Options

A. Short protrusible and attached at distal end
B. Short protrusible and attached at front end
C. Long nonprotrusible attached at front end
D. Long protrusible attached at front end

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of the Frog's Tongue**:
- The frog's tongue is described as long and fleshy, indicating that it has a considerable length and is made up of soft tissue.

2. **Protrusibility**:
- The tongue of the frog is highly protrusible, meaning it can extend outward. This ability is crucial for the frog's feeding mechanism, allowing it to catch prey effectively.

3. **Attachment Point**:
- The tongue is attached at the front end to the inner border of the lower jaw. This positioning allows the tongue to be thrust forward when capturing prey.

4. **Functionality**:
- The upper part of the tongue contains mucous glands and small papillae. The mucous glands help make the tongue sticky, which is advantageous for holding onto slippery prey.

5. **Evaluating the Options**:
- The options provided in the question are:
- Short, protrusible, and attached at distal end
- Short, protrusible, and attached at front end
- Long, non-protrusible, attached at front end
- Long, protrusible, attached at front end
- Based on the characteristics discussed, the correct option is "Long, protrusible, attached at front end".

6. **Conclusion**:
- Therefore, the correct answer to the question about the tongue of the frog is that it is "long, protrusible, and attached at the front end".
