A typical vertebra of rabbit is

Options

A. Opisthocoelous
B. Procoelous
C. Amphicoelous
D. Amphiplatyan

Answer

To answer the question regarding the type of vertebra typical of a rabbit, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Vertebra Types**:
- Vertebrae can be classified based on the shape of their anterior and posterior surfaces. The types include Ophistosceles, Procelus, Amphiceles, and Amphiplatin.

2. **Defining Each Type**:
- **Ophistosceles**: The posterior surface is concave, and the anterior surface is convex. This type is common in the neck region.
- **Procelus**: The anterior surface is concave, and the posterior surface is convex. This type is often found in reptiles and anura.
- **Amphiceles**: Both the anterior and posterior surfaces are concave. This type is typically found in fishes.
- **Amphiplatin**: Both surfaces are flat (absence of concavity). This type is common in mammals, including rabbits.

3. **Identifying the Correct Type for Rabbits**:
- Since rabbits are mammals, we need to identify the vertebral type that is characteristic of mammals. The amphiplatin type, where both surfaces are flat, is typical for mammals.

4. **Conclusion**:
- Therefore, the typical vertebra of a rabbit is **Amphiplatin** (also known as Acoelus).

### Final Answer:
The typical vertebra of a rabbit is **Amphiplatin**.
