Transverse canal that joins longitudinal Haversian canals is known as Volkmann's canal. It is a characteristic feature of the bone of

Options

A. Frog
B. Fish
C. Toad
D. Rabbit

Answer

To solve the question regarding the transverse canal that joins longitudinal Haversian canals, known as Volkmann's canal, we need to identify the type of bone in which this feature is characteristic. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Haversian and Volkmann's Canals**:
- Haversian canals are longitudinal channels in bone that contain blood vessels and nerves.
- Volkmann's canals are transverse channels that connect Haversian canals.

2. **Identifying the Options**:
- The options provided are:
1. Frog
2. Fish
3. Toad
4. Rabbit

3. **Analyzing the Options**:
- **Frog**: Frogs are amphibians and do not have a bone structure that includes Haversian systems.
- **Fish**: Fish are part of the class Pisces and typically have a different skeletal structure, lacking Haversian systems.
- **Toad**: Like frogs, toads are also amphibians and do not possess the characteristic bone structure with Haversian canals.
- **Rabbit**: Rabbits are mammals, and mammalian bones are characterized by the presence of Haversian systems, including both Haversian and Volkmann's canals.

4. **Conclusion**:
- Since Volkmann's canals are a characteristic feature of mammalian bone structure, the correct answer is **Rabbit** (Option 4).

### Final Answer:
The transverse canal that joins longitudinal Haversian canals, known as Volkmann's canal, is a characteristic feature of the bone of **Rabbit** (Option 4).
